Poisoned is a debuff which prevents health regeneration and causes the afflicted NPC or player to lose 2 health per second. A player is immune if they have a Bezoar or its upgrades equipped. Debuffed entities will also gain a green tint, and players will squint for the debuff's duration.
Enemies immune to Poisoned are also immune to Venom.

Poisoned as inflicted by a dart trap.
