Vampire
Feeding restores Coen. Animals can provide blood, and feeding on people carries consequences. The walkthrough fills in the economics. Human blood is the most effective source; animals work and are less efficient, which makes a no-kill run viable but slower. Feeding also raises Corruption — so every drink is simultaneously a heal, a moral position, and progress toward the deeper Vampirism nodes. And the bar itself is doing double duty. At night Coen's health bar is also his hunger, and he begins every night already thirsting. The first item on a night's agenda is therefore always the same one, whether or not you planned for it.
