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: Poisoned, Confused, Cursed Inferno, Venom, Frostburn and On Fire!. Players can also inflict Bleeding on enemies via the console/mobile-exclusive Tizona.
The Nurse can cancel debuffs at a cost of 7 50 per active debuff.
