+# Crookfinger's Bestiary
+

+
+> *Ah, master, you want to know who lives in your dungeon? Sit down. Mind the bones. I have written everything down -
+> lovingly about our own, and with a peg on my nose about the others.*
+> *- Crookfinger, imp, advisor, keeper of the tea*
+
+Every creature gains experience by fighting, training, studying and sparring. With every level it grows tougher
+(+15% health, +12% attack per level), its badge changes (bronze chevrons, silver bars, golden stars) and its gear grows
+(shoulder pieces, helmet, cape, golden armour with a crown and a halo). Its attacks look bigger, too.

+### Pit Imp
+
+<img src="docs/img/units/worker_1.png" width="72" alt="Pit Imp, level 1"> <img src="docs/img/units/worker_5.png" width="72" alt="Pit Imp, level 5"> <img src="docs/img/units/worker_10.png" width="72" alt="Pit Imp, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 45 | 3 every 1.0 s (3/s) | close combat | 3.2 tiles/s | 0 gold |
+
+**Comes for:** the dungeon itself; the summon spell brings more  
+**Loves:** Treasury  
+**From level 3:** Old hand - digs a quarter faster.
+
+My little cousins. They dig, they claim, they carry gold, they repair towers and they never complain - well, they complain, but in a language nobody understands.
+
+Up to five imps help each other with one task. Treat them well: without imps there is no dungeon.
+
+### Kobold
+
+<img src="docs/img/units/kobold_1.png" width="72" alt="Kobold, level 1"> <img src="docs/img/units/kobold_5.png" width="72" alt="Kobold, level 5"> <img src="docs/img/units/kobold_10.png" width="72" alt="Kobold, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 75 | 8 every 0.9 s (9/s) | close combat | 2.6 tiles/s | 40 gold |
+
+**Comes for:** any lair: always the first through the portal  
+**Loves:** Training Hall  
+**Cannot stand:** Shadow Mage  
+**From level 5:** Dash - leaps at enemies a few tiles away with a heavy blow.
+
+Small, scaly, sharp-toothed and endlessly enthusiastic. A kobold will fight anything, including things ten times its size, and lose with a happy face.
+
+Cheap to keep, quick on its feet. I keep a jar of their shed scales on my shelf.
+
+### Cave Spider
+
+<img src="docs/img/units/spider_1.png" width="72" alt="Cave Spider, level 1"> <img src="docs/img/units/spider_5.png" width="72" alt="Cave Spider, level 5"> <img src="docs/img/units/spider_10.png" width="72" alt="Cave Spider, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 95 | 10 every 1.0 s (10/s) | close combat | 2.9 tiles/s | 60 gold |
+
+**Comes for:** a mushroom garden of 6+ tiles  
+**Loves:** Mushroom Garden  
+**Cannot stand:** Giant Bat  
+**From level 4:** Web - its bites often leave enemies stuck and slow.
+
+Eight legs, eight eyes and a heart of pure velvet. Cave spiders love the damp warmth of a mushroom garden and the crunchy sound of armour.
+
+Quick and tough. Do not let the knights see them first: knights scream in a very high voice.
+
+### Shadow Mage
+
+<img src="docs/img/units/mage_1.png" width="72" alt="Shadow Mage, level 1"> <img src="docs/img/units/mage_5.png" width="72" alt="Shadow Mage, level 5"> <img src="docs/img/units/mage_10.png" width="72" alt="Shadow Mage, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 60 | 13 every 1.4 s (9/s) | 4.5 tiles | 2.0 tiles/s | 110 gold |
+
+**Comes for:** a library of 6+ tiles  
+**Loves:** Library  
+**Cannot stand:** Kobold, Stone Ogre  
+**From level 6:** Shadow step - badly hurt in a fight, it vanishes back to its bed.
+
+Shadow mages read everything, forget nothing and hurl dark bolts from a safe distance. They are polite, quiet and slightly terrifying.
+
+Fragile, so keep them behind the ogres. They pay you back in burnt paladins.
+
+### Stone Ogre
+
+<img src="docs/img/units/ogre_1.png" width="72" alt="Stone Ogre, level 1"> <img src="docs/img/units/ogre_5.png" width="72" alt="Stone Ogre, level 5"> <img src="docs/img/units/ogre_10.png" width="72" alt="Stone Ogre, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 230 | 20 every 1.4 s (14/s) | close combat | 1.8 tiles/s | 150 gold |
+
+**Comes for:** a training hall of 9+ tiles  
+**Loves:** Training Hall  
+**Cannot stand:** Shadow Mage, Cogling  
+**From level 4:** Stomp - shakes the ground: enemies around it are hurt and stunned.
+
+A stone ogre is a wall that walks and hugs. Mostly it hugs enemies, and they do not get up again.
+
+Slow, stubborn and wonderfully sturdy. Feed it well, pay it on time and it will stand in front of your core until the end of the world.
+
+### Jailer
+
+<img src="docs/img/units/jailer_1.png" width="72" alt="Jailer, level 1"> <img src="docs/img/units/jailer_5.png" width="72" alt="Jailer, level 5"> <img src="docs/img/units/jailer_10.png" width="72" alt="Jailer, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 260 | 16 every 1.3 s (12/s) | close combat | 1.6 tiles/s | 140 gold |
+
+**Comes for:** a torture chamber of 6+ tiles  
+**Loves:** Torture Chamber  
+**Cannot stand:** Flame Priestess  
+**From level 7:** Shackle - its blows sometimes chain enemies in place.
+
+The jailer pulls enemies close with his chain and has a gift for persuasion: prisoners he looks after change sides much more often.
+
+Big, quiet, hums while he works. Children love him. Well, ours do.
+
+### Flame Priestess
+
+<img src="docs/img/units/priestess_1.png" width="72" alt="Flame Priestess, level 1"> <img src="docs/img/units/priestess_5.png" width="72" alt="Flame Priestess, level 5"> <img src="docs/img/units/priestess_10.png" width="72" alt="Flame Priestess, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 70 | 14 every 1.6 s (9/s) | 5.0 tiles | 2.0 tiles/s | 120 gold |
+
+**Comes for:** a temple of 6+ tiles  
+**Loves:** Temple  
+**Cannot stand:** Jailer  
+**From level 5:** Healing pulse - heals all hurt creatures around her at once.
+
+The flame priestess throws fireballs that splash onto everyone around the target, and she heals the soul core with her prayers.
+
+She sleeps on glowing embers and smells of cinnamon. Do not ask her about the knights who burned her temple. Just let her work.
+
+### Chainbreaker
+
+<img src="docs/img/units/chainbreaker_1.png" width="72" alt="Chainbreaker, level 1"> <img src="docs/img/units/chainbreaker_5.png" width="72" alt="Chainbreaker, level 5"> <img src="docs/img/units/chainbreaker_10.png" width="72" alt="Chainbreaker, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 600 | 36 every 1.1 s (33/s) | close combat | 2.3 tiles/s | 400 gold |
+
+**Comes for:** a big dungeon: 40+ room tiles, a Lv 5 veteran and 4000 gold  
+**Loves:** Training Hall  
+**From level 6:** Whirlwind - spins its axes through every enemy around it.
+
+A legend. Twin axes, broken chains, and a temper that has flattened whole fortresses. Only one at a time, and only for a master who is worth it.
+
+Every swing also hits a second enemy. He gets restless when the dungeon is small - give him space and enemies, and he is yours.
+
+### Cogling
+
+<img src="docs/img/units/cogling_1.png" width="72" alt="Cogling, level 1"> <img src="docs/img/units/cogling_5.png" width="72" alt="Cogling, level 5"> <img src="docs/img/units/cogling_10.png" width="72" alt="Cogling, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 90 | 9 every 0.9 s (10/s) | close combat | 2.4 tiles/s | 70 gold |
+
+**Comes for:** a forge of 6+ tiles  
+**Loves:** Forge  
+**Cannot stand:** Stone Ogre  
+**From level 4:** Bomb - throws a home-made bomb that explodes among the enemies.
+
+A cogling is soot, brass goggles and pure enthusiasm. It builds traps two and a half times as fast as anyone else and hums while it hammers.
+
+It cannot fight much, but every corridor it touches becomes a terrible place to walk. I adore them.
+
+### Revenant
+
+<img src="docs/img/units/revenant_1.png" width="72" alt="Revenant, level 1"> <img src="docs/img/units/revenant_5.png" width="72" alt="Revenant, level 5"> <img src="docs/img/units/revenant_10.png" width="72" alt="Revenant, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 160 | 14 every 1.2 s (12/s) | close combat | 1.9 tiles/s | 30 gold |
+
+**Comes for:** rises from the graveyard  
+**Loves:** Graveyard  
+**Cannot stand:** Flame Priestess  
+**From level 5:** Life drain - heals itself by a third of the damage it deals.
+
+A revenant does not eat, does not sleep and does not complain - the perfect employee, if you can stand the smell.
+
+It drinks the strength of those it strikes once it has some experience. The priestess and it do not get along, for obvious reasons.
+
+### Giant Bat
+
+<img src="docs/img/units/bat_1.png" width="72" alt="Giant Bat, level 1"> <img src="docs/img/units/bat_5.png" width="72" alt="Giant Bat, level 5"> <img src="docs/img/units/bat_10.png" width="72" alt="Giant Bat, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 55 | 6 every 0.7 s (9/s) | close combat | 3.6 tiles/s | 30 gold |
+
+**Comes for:** an aerie of 4+ tiles  
+**Loves:** Aerie  
+**Cannot stand:** Cave Spider  
+**From level 5:** Shriek - a piercing cry that stuns enemies nearby.
+
+Giant bats! Fast, cheeky, and they fly over water and lava. They patrol the edges of your realm and dive at lonely enemies.
+
+Weak alone, a plague in swarms. They flee when badly hurt and come back once they have rested.
+
+### Chain Gargoyle
+
+<img src="docs/img/units/gargoyle_1.png" width="72" alt="Chain Gargoyle, level 1"> <img src="docs/img/units/gargoyle_5.png" width="72" alt="Chain Gargoyle, level 5"> <img src="docs/img/units/gargoyle_10.png" width="72" alt="Chain Gargoyle, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 260 | 15 every 1.2 s (12/s) | close combat | 2.2 tiles/s | 120 gold |
+
+**Comes for:** an aerie of 6+ tiles and a torture chamber of 4+  
+**Loves:** Torture Chamber  
+**Cannot stand:** Arcane Owl  
+**From level 5:** Stone form - badly hurt, it turns to stone and takes half damage for a while.
+
+A chain gargoyle is carved stone with bad manners and a soft spot for dungeons with a proper torture chamber.
+
+Tough as a castle wall, flies over rivers and does not mind arrows at all. It sits very still in the aerie - that is how it relaxes.
+
+### Arcane Owl
+
+<img src="docs/img/units/owl_1.png" width="72" alt="Arcane Owl, level 1"> <img src="docs/img/units/owl_5.png" width="72" alt="Arcane Owl, level 5"> <img src="docs/img/units/owl_10.png" width="72" alt="Arcane Owl, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 70 | 12 every 1.3 s (9/s) | 4.5 tiles | 2.8 tiles/s | 100 gold |
+
+**Comes for:** an aerie of 6+ tiles and a library of 6+  
+**Loves:** Library  
+**Cannot stand:** Chain Gargoyle  
+**From level 5:** Volley - every bolt is followed by a second one at another enemy.
+
+The arcane owl has read every book in your library twice and now shoots glowing bolts at heroes from the air.
+
+Clever, fragile and terribly judgemental. It hoots when you build crooked rooms.
+
+### Ember Wyrm
+
+<img src="docs/img/units/wyrm_1.png" width="72" alt="Ember Wyrm, level 1"> <img src="docs/img/units/wyrm_5.png" width="72" alt="Ember Wyrm, level 5"> <img src="docs/img/units/wyrm_10.png" width="72" alt="Ember Wyrm, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Wage |
+|---|---|---|---|---|
+| 650 | 30 every 1.4 s (21/s) | 3.0 tiles | 2.5 tiles/s | 380 gold |
+
+**Comes for:** an aerie of 16+ tiles and a treasury of 16+ (only one)  
+**Loves:** Treasury  
+**Cannot stand:** Giant Bat  
+**From level 7:** Inferno - its fire breath spreads much wider.
+
+An ember wyrm. In your dungeon. Breathing fire on knights. Master, I may cry.
+
+Very rare, very strong, burns everything around its target. It wants a huge aerie and a rich treasury, and it will not share the sky with another wyrm.
+
+## The humans
+
+> *Hold your nose, master. Here come the heroes.*
+
+### Knight
+
+<img src="docs/img/units/knight_1.png" width="72" alt="Knight, level 1"> <img src="docs/img/units/knight_5.png" width="72" alt="Knight, level 5"> <img src="docs/img/units/knight_10.png" width="72" alt="Knight, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Bounty |
+|---|---|---|---|---|
+| 140 | 11 every 1.1 s (10/s) | close combat | 1.9 tiles/s | 120 gold |
+
+The backbone of the Order: polished, punctual and utterly devoid of imagination. Knights march in circles, sing about the sun and smell of boot wax.
+
+They hit hard and hold the line. Disgusting. Capture them if you can - some of them can be persuaded in the torture chamber.
+
+### Archer
+
+<img src="docs/img/units/archer_1.png" width="72" alt="Archer, level 1"> <img src="docs/img/units/archer_5.png" width="72" alt="Archer, level 5"> <img src="docs/img/units/archer_10.png" width="72" alt="Archer, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Bounty |
+|---|---|---|---|---|
+| 75 | 9 every 1.3 s (7/s) | 4.5 tiles | 2.1 tiles/s | 100 gold |
+
+Archers stand far away, shoot from behind walls and call it bravery. They wear little green hats. Little green hats, master.
+
+Weak up close. Send the bats, they hate it.
+
+### Priest
+
+<img src="docs/img/units/priest_1.png" width="72" alt="Priest, level 1"> <img src="docs/img/units/priest_5.png" width="72" alt="Priest, level 5"> <img src="docs/img/units/priest_10.png" width="72" alt="Priest, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Bounty |
+|---|---|---|---|---|
+| 80 | 5 every 1.5 s (3/s) | 3.5 tiles | 1.9 tiles/s | 120 gold |
+
+Priests heal other heroes from afar and pray loudly enough to curdle milk. Every one of them has a sermon about us, and none of them is short.
+
+Kill them first, or the fight never ends.
+
+### Dwarf Miner
+
+<img src="docs/img/units/dwarf_1.png" width="72" alt="Dwarf Miner, level 1"> <img src="docs/img/units/dwarf_5.png" width="72" alt="Dwarf Miner, level 5"> <img src="docs/img/units/dwarf_10.png" width="72" alt="Dwarf Miner, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Bounty |
+|---|---|---|---|---|
+| 110 | 9 every 1.0 s (9/s) | close combat | 2.0 tiles/s | 100 gold |
+
+The dwarf miners of the Order dig their way through earth three times as fast as anyone else, straight towards your treasury. They have no respect for walls - your walls in particular.
+
+Reinforce your walls. Steel walls make them weep.
+
+### Fairy Spy
+
+<img src="docs/img/units/fairy_1.png" width="72" alt="Fairy Spy, level 1"> <img src="docs/img/units/fairy_5.png" width="72" alt="Fairy Spy, level 5"> <img src="docs/img/units/fairy_10.png" width="72" alt="Fairy Spy, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Bounty |
+|---|---|---|---|---|
+| 70 | 5 every 1.2 s (4/s) | 3.5 tiles | 3.2 tiles/s | 150 gold |
+
+The Order's little informer: a glowing gnat with wings, sent ahead to find your traps and tell everybody. Once it has seen a trap, the heroes smash it.
+
+It also sprinkles healing dust on the heroes. Swat it first. Twice, to be sure.
+
+### Battle Mage
+
+<img src="docs/img/units/battlemage_1.png" width="72" alt="Battle Mage, level 1"> <img src="docs/img/units/battlemage_5.png" width="72" alt="Battle Mage, level 5"> <img src="docs/img/units/battlemage_10.png" width="72" alt="Battle Mage, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Bounty |
+|---|---|---|---|---|
+| 120 | 18 every 1.8 s (10/s) | 5.0 tiles | 1.8 tiles/s | 250 gold |
+
+A mage in the Order's robes who thinks walls are a personal insult. Reinforced walls burst under his fireballs, and he never stops talking about it.
+
+Fragile up close. Steel walls annoy him most - good.
+
+### Giant
+
+<img src="docs/img/units/giant_1.png" width="72" alt="Giant, level 1"> <img src="docs/img/units/giant_5.png" width="72" alt="Giant, level 5"> <img src="docs/img/units/giant_10.png" width="72" alt="Giant, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Bounty |
+|---|---|---|---|---|
+| 900 | 34 every 1.6 s (21/s) | close combat | 1.3 tiles/s | 600 gold |
+
+A giant is what happens when a knight eats his vegetables for three hundred years. Slow, enormous, and it treats doors as a suggestion.
+
+It wrecks traps simply by standing next to them. Revolting manners. Hit it with everything, preferably from afar.
+
+### Paladin of Light
+
+<img src="docs/img/units/paladin_1.png" width="72" alt="Paladin of Light, level 1"> <img src="docs/img/units/paladin_5.png" width="72" alt="Paladin of Light, level 5"> <img src="docs/img/units/paladin_10.png" width="72" alt="Paladin of Light, level 10">
+
+*Level 1, 5 and 10 - the gear grows with the rank.*
+
+| Health | Attack | Range | Speed | Bounty |
+|---|---|---|---|---|
+| 700 | 26 every 1.2 s (22/s) | close combat | 1.7 tiles/s | 1000 gold |
+
+Paladins of light: glowing, enormous and absolutely convinced of themselves. They are the Order's heroes and have the bounty to prove it.
+
+Tough as an ogre, twice as smug. Bring everything you have, and maybe a bucket for the glare.
+
+## The neutrals
+
+### Cave dwarf
+
+<img src="docs/img/units/dwarf_5.png" width="72" alt="cave dwarf">
+
+Not all dwarves serve the Order. The cave dwarves keep to themselves in caves full of gold and gems and want nothing but to be left alone.
+
+They fight whoever comes close and never leave their cave. The more your army grows, the tougher they get - they have heard of you. Some of their chests hold the plans of the rune forge tower.
+
+## Rooms of the dungeon
+
+| | Room | |
+|---|---|---|
+| <img src="docs/img/icons/treasury.png" width="40"> | **Treasury** | Stores gold: +500 capacity per tile. *Where the gold sleeps. The richer the treasury, the happier everyone is. Imps bring their loads to the nearest treasury, and payday is paid from here. | Each tile holds 500 gold; the core keeps a reserve when it is full.* |
+| <img src="docs/img/icons/lair.png" width="40"> | **Lair** | One bed per tile. Determines how many creatures come. *Every creature wants its own bed, and only arrives when one is free. A big lair also brings new creatures faster.* |
+| <img src="docs/img/icons/farm.png" width="40"> | **Mushroom Garden** | Food for creatures. With 6 tiles or more, cave spiders come. *Mushrooms! Juicy, pale, slightly glowing. Hungry creatures are grumpy creatures, and spiders love a big garden.* |
+| <img src="docs/img/icons/training.png" width="40"> | **Training Hall** | Creatures gain levels (costs gold). With 9 tiles or more, stone ogres come. *Creatures train here and gain levels. Training is billed on payday. Ogres come for a big hall.* |
+| <img src="docs/img/icons/library.png" width="40"> | **Library** | Creatures generate mana. With 6 tiles or more, shadow mages come. *Research, quiet reading and the occasional explosion. Mages and owls come for a library.* |
+| <img src="docs/img/icons/torture.png" width="40"> | **Torture Chamber** | Holds one prisoner per 2 tiles. Defeated heroes are carried here and tortured until they die or defect. From 6 tiles on, Jailers come. *Captured heroes end up here. With time and a jailer, some of them change sides. Gargoyles feel at home with one.* |
+| <img src="docs/img/icons/prison.png" width="40"> | **Prison** | Captured heroes sit in cells here - apart from the torture chamber. Without torture they do not change sides, and hunger wears them down. Pick a prisoner up with the hand to move it to the torture chamber. *Rows of cells. Heroes rot here quietly until somebody decides what to do with them.* |
+| <img src="docs/img/icons/temple.png" width="40"> | **Temple** | Creatures pray here: more mana than studying, and it lifts their mood. From 6 tiles on, Flame Priestesses come. *Prayers heal the soul core and keep spirits high. The flame priestess comes for a temple.* |
+| <img src="docs/img/icons/aerie.png" width="40"> | **Aerie** | Perches and nests for flying creatures. 4+ tiles attract giant bats; with a torture chamber chain gargoyles, with a library arcane owls; a big aerie (16+) and treasury (16+) may lure an ember wyrm. Flyers cross water and lava. *Perches and nests for flying creatures. Bats, gargoyles, owls and even the ember wyrm need room here.* |
+| <img src="docs/img/icons/forge.png" width="40"> | **Forge** | Creatures manufacture traps and doors here - work, no gold. Finished pieces wait in crates until an imp installs them. Coglings come for a forge of 6+ tiles. *The clang of hammers, the smell of hot iron. Every trap and door is made here first - the more creatures work, the faster.* |
+| <img src="docs/img/icons/graveyard.png" width="40"> | **Graveyard** | The fallen - heroes and creatures - are buried here. After a while some of them rise as revenants and serve you. *Moss, stones and fresh earth. Nobody stays dead for long down here.* |
+| <img src="docs/img/icons/guardpost.png" width="40"> | **Guard Post** | Creatures hold the position here for a while and watch far: they attack every enemy that comes into view. *A brazier, a banner and a bored creature with sharp eyes.* |
+| <img src="docs/img/icons/arena.png" width="40"> | **Arena** | Creatures spar in pairs: twice as much experience as training and free of charge, but they get bruised. *Sand, sweat and the occasional tooth. Experience comes fast here.* |
+| <img src="docs/img/icons/altar.png" width="40"> | **Sacrifice Altar** | Drop a creature on the altar to sacrifice it. Certain pairs of sacrifices bring a rare creature, otherwise the dungeon is blessed: better mood and mana. *Black marble that drinks. Some say it listens to pairs. Ogre and spider, mage and bat, jailer and priestess, kobold and cogling...* |
+
+## Towers, traps and doors
+
+| | | |
+|---|---|---|
+| <img src="docs/img/icons/arrow.png" width="40"> | **Arrow Tower** | Cheap and fast. Arrows pierce up to two more heroes behind the target. Click your tower with this tool to upgrade it. *The arrow pierces up to two more enemies behind the target. Cheap and reliable.* |
+| <img src="docs/img/icons/cannon.png" width="40"> | **Cannon Tower** | Slow, long range, splash damage that knocks heroes back. Cannot hit targets right next to it. *Splash damage and knockback - push the knights into the lava.* |
+| <img src="docs/img/icons/magic.png" width="40"> | **Magic Tower** | Uses mana per shot. Never misses, slows the target and jumps to a second hero. *Never misses, slows the target and jumps on to a second enemy. Uses mana.* |
+| <img src="docs/img/icons/rune.png" width="40"> | **Rune Forge Tower** | Plans from a dwarven chest: built for free, one tower per chest. Huge range, rune bolts jump on to three more enemies. Sell it and the base tower comes back once, in the next mission. *The masterpiece of the cave dwarves: rune bolts that jump on to three more enemies, enormous range and walls of granite. One free build per chest; sell it and it comes back once.* |
+| <img src="docs/img/icons/spikes.png" width="40"> | **Spike Pit** | Spikes shoot up when an enemy steps on it. Strikes again and again. *Simple, honest, reusable. Knights hate it when the floor bites back.* |
+| <img src="docs/img/icons/poison.png" width="40"> | **Poison Vent** | Releases a cloud of poison that hurts every enemy inside for a while. *A puff of green and a lot of coughing. Best in narrow corridors.* |
+| <img src="docs/img/icons/fire.png" width="40"> | **Fire Jet** | A demon head spits a jet of fire at enemies up to three tiles away. *A demon head with a temper. Put it where the heroes queue.* |
+| <img src="docs/img/icons/roller.png" width="40"> | **Stone Roller** | Sends a boulder rolling down the corridor: hits hard and knocks enemies aside. *A boulder and a long corridor - physics does the rest.* |
+| <img src="docs/img/icons/alarm.png" width="40"> | **Alarm Bell** | Rings when enemies come near: your creatures nearby rush to fight them. *Not dangerous itself, but it calls everybody who is.* |
+| <img src="docs/img/icons/mine.png" width="40"> | **Rune Mine** | Explodes once with great force when an enemy steps close. *One step too many and the corridor gets redecorated.* |
+| <img src="docs/img/icons/frost.png" width="40"> | **Frost Glow** | An ice crystal: enemies around it are slowed and chilled, always. *Cold makes heroes slow, and slow heroes make easy targets.* |
+| <img src="docs/img/icons/door_wood.png" width="40"> | **Wooden Door** | Your creatures walk through, enemies have to smash it. Click a door again to lock it. *Keeps the draught and the knights out - for a while.* |
+| <img src="docs/img/icons/door_iron.png" width="40"> | **Iron Door** | A heavy door that takes a long time to break. Click a door again to lock it. *Heavy, riveted, stubborn. Bring a battering ram, heroes.* |
+| <img src="docs/img/icons/door_magic.png" width="40"> | **Magic Door** | The strongest door: it hurls back whoever beats on it. Click a door again to lock it. *Strike it and it strikes back. Locked, it is the end of every corridor.* |
+
+## Spells
+
+| | Spell | Mana | |
+|---|---|---|---|
+| <img src="docs/img/icons/lightning.png" width="40"> | **Lightning** | 50 | 55 damage to heroes in the area. |

+| <img src="docs/img/icons/cavein.png" width="40"> | **Cave-in** | 70 | The ceiling comes down: open floor turns back into earth (3x3), whoever stands there is hurt and pushed out. Blocks corridors. |
+| <img src="docs/img/icons/haste.png" width="40"> | **Haste** | 30 | Your creatures around the spot move and act much faster for 30 seconds. |
+| <img src="docs/img/icons/stoneskin.png" width="40"> | **Stoneskin** | 40 | Your creatures around the spot take only half damage for 30 seconds. |

+| <img src="docs/img/icons/invisible.png" width="40"> | **Invisibility** | 50 | One creature becomes invisible for 25 seconds: enemies and towers ignore it until it attacks. |
+| <img src="docs/img/icons/plague.png" width="40"> | **Plague** | 80 | A sickness that eats at the enemies around the spot and jumps from one to the next. |

+# Installing and running DungeonCraft
+
+> *Technical matters, master. Crookfinger does not understand half of it, but the imps say it works.*
+
+**Just want to play?** Download [`play/DungeonCraft.html`](play/DungeonCraft.html) and open it in a browser -
+no server, no installation, no login. Savegames are downloaded as `.dcsave` files and loaded again with
+*Load Game* (or dropped onto the game window).
+
+Everything below is for running your own server (with user accounts and savegames on the server),
+building the game yourself or working on it.
+
+## Running a server
+
+The easiest way is Docker; the image builds the WASM file and serves it with nginx. A second container runs the savegame service (see below):
+
+```sh
+docker compose up -d --build
+# open http://localhost:18093
+```
+
+### Install as an app (PWA)
+
+DungeonCraft is a progressive web app: browsers offer to install it (Chrome/Edge: install icon in the address bar or "Install app" in the menu; Android: "Add to home screen"; iOS Safari: Share → "Add to Home Screen"). The installed game starts in full screen and also works offline (the savegame list on the server then falls back to savegame files).
+
+Browsers only allow the installation over **HTTPS** (or on `localhost`), so a public installation needs a reverse proxy with a certificate in front of port 18093.
+
+### Building without Docker
+
+Requirements: Rust with the `wasm32-unknown-unknown` target.
+
+```sh
+rustup target add wasm32-unknown-unknown
+cargo build --release --target wasm32-unknown-unknown
+cp target/wasm32-unknown-unknown/release/dungeoncraft.wasm www/
+cp ~/.cargo/registry/src/*/macroquad-*/js/mq_js_bundle.js www/
+python3 -m http.server 8080 -d www   # open http://localhost:8080
+```
+
+### Testing the game logic
+
+The tests run natively: a headless simulation of whole games, a savegame round trip, rendering of all music modules and the audio engine:
+
+```sh
+cargo test --release
+```
+
+## Music
+
+The soundtrack consists of FastTracker 2 modules in `assets/music/`, generated by `tools/compose_music.py` (`python3 tools/compose_music.py`). They can be opened and edited in MilkyTracker. The game plays them with its own XM/MOD replayer (`src/xm.rs`); sound effects are synthesised chip sounds (`src/sfx.rs`). Both are mixed in `src/audio.rs` and streamed to the browser by `www/dc_plugin.js`.
+
+## Controls
+
+| Input | Action |
+|---|---|
+| Esc | Pause menu (save, load, settings) |
+| Left click / drag | Use the active tool (dig and rooms: drag a rectangle) |
+| Right click | Drop a unit from your hand (prisoners anywhere on your ground; onto a free torture place = locked up) |
+| Shift + left click (hand) | Backhand own units (15 s faster, costs a little HP and mood) / punch heroes on your ground (15 damage, 1 s stun) |
+| Right drag, WASD, arrows, screen edge | Move the camera |
+| Middle drag, Q/E, R/F | Rotate / tilt the camera |
+| Mouse wheel | Zoom |
+| 1–9, 0, X, V, K, J, B, C, T, U, Y, O, N | Select a tool or spell (more can be bound in the settings) |
+| P / Space | Pause |
+| M, +/- | Sound on/off, volume |
+| G | Tile outlines on/off |
+| H | Help |
+
+All keys except Esc and the arrow keys can be changed in Settings → Keys.
+
+The toolbar groups the tools into categories (Dig, Hand, Rooms, Towers, Traps, Spells, Orders) plus a menu button; categories with several tools open a row above the toolbar. The keys select tools directly.
+
+### Touch (phones and tablets)
+
+The touch interface switches on automatically on touch devices or after the first touch (Settings → Game → Touch interface: Auto / On / Off). It uses a larger interface and these gestures:
+
+| Gesture | Action |
+|---|---|
+| Tap | Use the tool (hand: pick up a unit; spells, flag, towers: at that spot) |
+| Drag | Dig, rooms and sell: mark a rectangle; other tools: move the map |
+| Two fingers | Move the map, pinch to zoom, twist to rotate the camera |
+| Long press | Information about the spot; hand: drop the units there |
+| Double tap (hand) | Backhand own units / punch heroes on your ground |
+
+The savegame name is entered with the browser's text dialog when the name field is tapped.
+
+## Savegames
+
+When the game is served together with the service (`server/`, started by `docker compose`), it starts with a **login**:
+
+- The very first login creates the **admin account** with the entered name and password - do this right after installing.
+- The admin creates further users (title screen -> *Account*); every user can change the password there and log out.
+- Every user only sees the **own savegames** on the server: *Save Game* and *Load Game* open the list (save under a new name, overwrite, load, delete).
+- *Download Standalone* (title screen) downloads `DungeonCraft.html`: the whole game in one file, without login and without server. Savegame files (*Download as file*) open there as well.
+
+If the service cannot be reached (for example the standalone file, `www/` opened as local files or a plain web server), there is no login and the game uses savegame files: *Save Game* downloads a `.dcsave` file (JSON), *Load Game* opens the file picker; dropping the file onto the game window works too.
+
+The game also autosaves into the browser every two minutes and when the tab is closed; *Continue* on the title screen resumes from there.
+
+### Savegame service
+
+A small Rust service (axum) in `server/` keeps the user accounts (Argon2 password hashes) and the savegames as files in the Docker volume `savegames` (one folder per user). nginx forwards `/api/` to it; the service itself is not published. The standalone file is served under `/standalone/` only for logged-in users (nginx `auth_request`).
+
+| Request | Meaning |
+|---|---|
+| `GET /api/health` | `ok` when the service runs (`ok setup` while there is no account yet) |
+| `POST /api/login` | `{name, password}` -> `{token, name, admin}`; the first login creates the admin |
+| `POST /api/logout`, `GET /api/me`, `POST /api/password` | session, own account, change password |
+| `GET/POST /api/users`, `DELETE /api/users/{name}` | admin: list, create, delete users |
+| `GET /api/saves` | own savegames (id, name, date, map size, wave, play time), newest first |
+| `POST /api/saves?name=...` | store a new savegame (body: savegame JSON) |
+| `PUT /api/saves/{id}?name=...` | overwrite a savegame |
+| `GET /api/saves/{id}` | savegame JSON |
+| `DELETE /api/saves/{id}` | delete a savegame |
+
+A forgotten password is set again on the server with `docker compose stop saves && docker compose run --rm --no-deps saves dungeoncraft-saves set-password <name> '<password>' && docker compose up -d saves` (ends the user's sessions). To start over with no accounts at all, delete `users.json` and `sessions.json` in the `savegames` volume.
+
+All requests except health and login need `Authorization: Bearer <token>`. Limits: 1 MB per savegame, 500 MB in total, 30 write requests and 20 login attempts per minute. Settings: `SAVE_DIR` (default `/data`), `LISTEN` (default `0.0.0.0:8080`).
+
+## Adding a language
+
+1. Copy `lang/en.lang` to `lang/<code>.lang` and translate the texts (placeholders `{0}`, `{1}` stay as they are).
+2. Add the file to `SOURCES` in `src/i18n.rs`.
+3. Note: the DINOBYTE font only covers the CP437 character set.
+
+## Refreshing the generated files
+
+| File | How |
+|---|---|
+| `play/DungeonCraft.html` | build the WASM file, then `python3 tools/make_standalone.py <www dir with dungeoncraft.wasm and mq_js_bundle.js> play/DungeonCraft.html` (the Docker image builds the same file under `/standalone/`) |
+| `docs/img/units`, `docs/img/icons` | `cargo test --release export_doc_images -- --ignored` |
+| `BESTIARY.md` | `python3 tools/make_bestiary.py` |

-## Running
+---
 
-The easiest way is Docker; the image builds the WASM file and serves it with nginx. A second container runs the savegame service (see below):
+## Wake up, master.
 
-```sh
-docker compose up -d --build
-# open http://localhost:18093
-```
+Yes, you. Don't look around, there's nobody else down here - just you, four imps and me, old **Crookfinger**.
 
-### Install as an app (PWA)
+A hundred years ago the Order of the Lightwatch smashed your soul core into shards and carried them off like trophies.
+They polished their boots, sang songs about the sun and forgot about you. **Big mistake.**
 
-DungeonCraft is a progressive web app: browsers offer to install it (Chrome/Edge: install icon in the address bar or "Install app" in the menu; Android: "Add to home screen"; iOS Safari: Share → "Add to Home Screen"). The installed game starts in full screen and also works offline (the savegame list on the server then falls back to savegame files).
+Your heart still beats. Hear that? *Lub-dub. Lub-dub.* That's the sound of a grudge.
 
-Browsers only allow the installation over **HTTPS** (or on `localhost`), so a public installation needs a reverse proxy with a certificate in front of port 18093.
+So pick up the pickaxe - well, point at the rock, the imps carry the pickaxes - and let's dig ourselves a realm.
+Gold is in the walls, creatures are waiting behind the portal, and the knights... the knights are about to have
+a very bad century.
 
-### Building without Docker
+<p align="center">
+  <img src="docs/screenshots/dungeon-heart.png" width="820" alt="The beating crystal heart, the demon gate and the dark towers">
+  <br><i>Your heart, master, held in chains on its obsidian throne. And the demon gate. I polished it myself.</i>
+</p>
 
-Requirements: Rust with the `wasm32-unknown-unknown` target.
+## What awaits you down here
 
-```sh
-rustup target add wasm32-unknown-unknown
-cargo build --release --target wasm32-unknown-unknown
-cp target/wasm32-unknown-unknown/release/dungeoncraft.wasm www/
-cp ~/.cargo/registry/src/*/macroquad-*/js/mq_js_bundle.js www/
-python3 -m http.server 8080 -d www   # open http://localhost:8080
-```
+**🕳 Dig your realm.** Mark the rock and your imps dig, claim the ground, carry gold, gems and diamonds to the
+treasury and hang torches on the walls. Up to five imps help each other with one job. Every tile you claim is *yours*.
 
-### Testing the game logic
+**🏰 Build rooms that bring the right guests.** A lair and a mushroom garden open the portal. A library brings
+shadow mages, a training hall stone ogres, a temple the flame priestess, an aerie giant bats, gargoyles, arcane
+owls - and maybe, one day, an **ember wyrm**. Fourteen rooms in total, from the forge to the sacrifice altar.
 
-The tests run natively: a headless simulation of whole games, a savegame round trip, rendering of all music modules and the audio engine:
+**👹 Keep them happy, or they leave.** Every creature wants a bed, food and its wage on payday - and it walks to the
+treasury to fetch it. Each has a favourite room, and some of them simply cannot stand each other.
+Put a mage next to an ogre and watch the fur fly. (Nobody dies. Probably.)
 
-```sh
-cargo test --release
-```
+**⚔ Train them into legends.** Ten ranks from Recruit to Warlord, with chevrons, bars and stars - and gear that grows
+with them, up to golden armour, a crown and a halo. With the level come abilities: the ogre learns to *stomp*, the mage
+to *step through shadows*, the chainbreaker to spin like a *whirlwind*.
 
-## Music
+<p align="center">
+  <img src="docs/screenshots/bridge-battle.png" width="820" alt="A battle at a bridge over an underground river">
+  <br><i>The knights brought a bridge. How thoughtful. Now they're bringing it back, one piece at a time.</i>

Both are mixed in `src/audio.rs` and streamed to the browser by `www/dc_plugin.js`.
+**🔥 Defend with towers, traps and doors.** Arrow spires, hellmouth cannons and dark spires on the walls. In the
+**forge** your creatures build spike pits, poison vents, fire jets, stone rollers, alarm bells, rune mines and
+frost glows - and doors of wood, iron and magic. Lock them, and nobody gets through. Not even the giant. Well. Not for a while.
 
-## Controls
+**✨ Cast nasty spells.** Lightning, healing, seer's eye, cave-in, haste, stoneskin, gold rain, invisibility,
+plague and quake. Your scholars **research** them in the library - one discovery after another.
 
-| Input | Action |
+**🌫 Explore the dark.** Everything beyond your walls is black until your creatures go there.
+Somewhere out there: a cave of neutral **dwarves** guarding gold and gems - and sometimes a chest with the plans
+of a dwarven **rune forge tower**. Islands in lava rivers. Mana springs. Creatures in chains, waiting to be freed.

+</p>
+
+**👑 Other masters want your realm, too.** Mossgrim the Mouldy (green, smells like a wet cellar) and Lady Nightwell
+(blue, writes threatening letters on scented paper) dig their own dungeons in free play and in the campaign.
+And the humans attack *everybody*. Let them bite each other first.
+
+**📜 A campaign of thirty missions.** Take back the shards of your soul core - from the first little outpost by the

+## How to play
+
+1. **Download [`play/DungeonCraft.html`](play/DungeonCraft.html)** and open it in your browser. That's all.
+   It runs offline, on desktop and on phones (touch controls switch on by themselves).
+2. Or **run your own server** with Docker - with user accounts, savegames on the server and the game as an
+   installable app: see **[INSTALL.md](INSTALL.md)**.

+| Right drag, WASD, screen edge | move the camera · middle drag, Q/E, R/F: rotate and tilt · wheel: zoom |
+| Esc | pause menu: save, load, settings, bestiary |
 
-All keys except Esc and the arrow keys can be changed in Settings → Keys.
+On phones: tap to use a tool, drag to mark or move, two fingers to zoom and turn, long press for information.
 
-The toolbar groups the tools into categories (Dig, Hand, Rooms, Towers, Spells, Orders) plus a menu button; categories with several tools open a row above the toolbar. The keys select tools directly.
+## Under the hood
 
-### Touch (phones and tablets)
+- **Rust**, compiled to **WebAssembly**, with [macroquad](https://github.com/not-fl3/macroquad) - one small module, no engine, no plugins.
+- A real 3D isometric world in pixel art: chunked meshes, flickering point lights, a glow pass, particles,
+  billboard sprites with eight viewing directions, every frame of it drawn by code - **no image files** except the font.
+- Procedural chiptune soundtrack as FastTracker 2 modules with its own XM replayer and synthesised sound effects.
+- A tiny Rust savegame server (axum, Argon2 passwords) - optional; without it the game uses savegame files.
+- English and German, more languages are one text file away.
 
-The touch interface switches on automatically on touch devices or after the first touch (Settings → Game → Touch interface: Auto / On / Off). It uses a larger interface and these gestures:
+## Made with Claude Code
 
-| Gesture | Action |
-|---|---|
-| Tap | Use the tool (hand: pick up a unit; spells, flag, towers: at that spot) |
-| Drag | Dig, rooms and sell: mark a rectangle; other tools: move the map |
-| Two fingers | Move the map, pinch to zoom, twist to rotate the camera |
-| Long press | Information about the spot; hand: drop the units there |
-| Double tap (hand) | Backhand own units / punch heroes on your ground |
-
-The savegame name is entered with the browser's text dialog when the name field is tapped.
-
-## Savegames
-
-When the game is served together with the service (`server/`, started by `docker compose`), it starts with a **login**:
-
-- The very first login creates the **admin account** with the entered name and password - do this right after installing.
-- The admin creates further users (title screen -> *Account*); every user can change the password there and log out.
-- Every user only sees the **own savegames** on the server: *Save Game* and *Load Game* open the list (save under a new name, overwrite, load, delete).
-- *Download Standalone* (title screen) downloads `DungeonCraft.html`: the whole game in one file, without login and without server. Savegame files (*Download as file*) open there as well.
-
-If the service cannot be reached (for example the standalone file, `www/` opened as local files or a plain web server), there is no login and the game uses savegame files: *Save Game* downloads a `.dcsave` file (JSON), *Load Game* opens the file picker; dropping the file onto the game window works too.
-
-The game also autosaves into the browser every two minutes and when the tab is closed; *Continue* on the title screen resumes from there.
-
-### Savegame service
-
-A small Rust service (axum) in `server/` keeps the user accounts (Argon2 password hashes) and the savegames as files in the Docker volume `savegames` (one folder per user). nginx forwards `/api/` to it; the service itself is not published. The standalone file is served under `/standalone/` only for logged-in users (nginx `auth_request`).
-
-| Request | Meaning |
-|---|---|
-| `GET /api/health` | `ok` when the service runs (`ok setup` while there is no account yet) |
-| `POST /api/login` | `{name, password}` -> `{token, name, admin}`; the first login creates the admin |
-| `POST /api/logout`, `GET /api/me`, `POST /api/password` | session, own account, change password |
-| `GET/POST /api/users`, `DELETE /api/users/{name}` | admin: list, create, delete users |
-| `GET /api/saves` | own savegames (id, name, date, map size, wave, play time), newest first |
-| `POST /api/saves?name=...` | store a new savegame (body: savegame JSON) |
-| `PUT /api/saves/{id}?name=...` | overwrite a savegame |
-| `GET /api/saves/{id}` | savegame JSON |
-| `DELETE /api/saves/{id}` | delete a savegame |
-
-A forgotten password is set again on the server with `docker compose stop saves && docker compose run --rm --no-deps saves dungeoncraft-saves set-password <name> '<password>' && docker compose up -d saves` (ends the user's sessions). To start over with no accounts at all, delete `users.json` and `sessions.json` in the `savegames` volume.
-
-All requests except health and login need `Authorization: Bearer <token>`. Limits: 1 MB per savegame, 500 MB in total, 30 write requests and 20 login attempts per minute. Settings: `SAVE_DIR` (default `/data`), `LISTEN` (default `0.0.0.0:8080`).
-
-## Adding a language
-
-1. Copy `lang/en.lang` to `lang/<code>.lang` and translate the texts (placeholders `{0}`, `{1}` stay as they are).
-2. Add the file to `SOURCES` in `src/i18n.rs`.
-3. Note: the DINOBYTE font only covers the CP437 character set.
