Etorphine

Etorphine is a type of painkiller in Pathologic. Ingesting it greatly increases the player's fatigue, meaning it is most effective if the player intends to sleep after ingesting it. Doing so will massively increase health regeneration while the player sleeps.

"A powerful narcotic painkiller. It's very good at reducing pain and has a similarly strong sedative effect (35s, -35e). Restores strength when sleeping (3e/ph, 3s/ph). It should be remembered that an overdose can lead to a severely weakened state and even death. Effective for ten hours."
