Putrid Leech

A cursed parasite worn on the head that grants permanent Lifesteal on all attacks and abilities. While equipped, the wearer cannot level up and dies instantly when downed. The Putrid Leech cannot be removed normally and returns to the quest inventory if its holder dies — unless it has been inserted into the Throbbing Artery. Obtained by defeating Guillotina 2's rematch, it is one of three quest items required to unlock and explore The Throbbing Domain.
