Debuffs are temporary, negative status effects. Unlike Buffs, they cannot be cancelled by right-clicking their icons.
Most debuffs can only be inflicted by enemies, on players. Players can inflict the following debuffs on enemies: Confused, Cursed Inferno, Ichor, Poisoned, Venom, Frostburn and On Fire!. Players can also inflict Bleeding on enemies via the console/mobile-exclusive Tizona.
In general, damaging debuffs will stack: If you are both Poisoned and On Fire!, you will take damage from both of them. However, Poisoned and Venom do not stack, and Poisoned will take precedence over Venom. Death always cancels any active buffs or debuffs.
The Nurse can cancel debuffs at a cost of 7 50 per active debuff.
