Torture chamber with prisoners and defectors, Jailer; temple with prayer, Flame Priestess

- defeated heroes are knocked out if the torture chamber has room; imps carry them in
- torture drains HP over ~100 s; ~40% defect (paladins ~25%) and become own creatures
- Jailer (6+ torture tiles): tanky melee that pulls enemies in with a chain
- temple: creatures pray for mana (more than studying) and mood
- Flame Priestess (6+ temple tiles): fireballs with splash, heals creatures and the Soul Core
- tests: prisoner chain + defect rate, temple prayer + core healing
