located a bug: after simping for Ethrex twice and becoming a demon, refusing to go for thirds will consistently (though temporarily) render him headless. Also, not sure if it's a bug or not, but Codex's Passion currently reads that it's supposed to give you a percentage of your health back, but I would only get flat numbers returned (i.e. a 2% regen while having 1300 max health only boosting me by exactly 2).
