Debuffs are temporary, negative status effects. Unlike Buffs, they cannot be cancelled by right-clicking the icon. Currently, all debuffs apply to players, but only Poisoned, Confused, Cursed Inferno, Venom, Frostburn and On Fire! can be inflicted onto enemy NPCs. (Console only.pngMobile only.pngThe Tizona also has a chance to cause Bleeding.)

Note that damaging debuffs don't stack; if you are both Poisoned and On Fire!, the latter will take precedence.

The Nurse can heal players debuffs, with a cost of 7 silver 50 copper per active debuff, however if the player has the Potion Sickness debuff then the icon will only be removed and not the buff itself until the timer hits 0.
