- every kind loves one room (working there lifts the mood) and cannot stand certain other kinds; close by they sour each other's mood and now and then brawl (they stop at 30% health)
- learned abilities: imps dig faster, kobold dash, spider web, mage shadow step, ogre stomp, jailer shackle, priestess healing pulse, chainbreaker whirlwind, bat shriek, gargoyle stone form, owl volley, wyrm inferno, cogling bomb
- bestiary lists likes, hatreds and the ability (highlighted from its level on)
