Debuffs

Debuffs are negative status effects inflicted on a player or enemy during combat or through various items or the environment. Active debuffs are shown as icons below the hotbar, along with their remaining duration. Debuffs are almost universally negative or at least malign effects, in contrast with buffs, over which the player has much more control.

In general, damaging debuffs will stack: If a player is both Poisoned and On Fire!, they will take damage from both debuffs. However, Poisoned and Acid Venom do not stack, and Poisoned will take precedence over Acid Venom. Death always cancels any active debuffs.

Unlike buffs, debuffs cannot be canceled by right-clicking their icons. The Nurse can cancel debuffs at a cost of 7 SC50 CC per active debuff. This does not apply to the Potion Sickness debuff, which cannot be canceled.

Trivia

• (Desktop, Console and Mobile versions) The maximum possible DPS that can be inflicted on an enemy with damaging debuffs is 1202. This can be achieved by consuming a Flask of Cursed Flames, wearing Huntress armor/Red Riding armor and a Magma Stone, firing a Venom Dart Trap, and using the Daybreak, Shadowflame Hex Doll, Blood Butcherer, Ice Boomerang, and Bone Javelins while having an Imp Staff and a Stardust Cell Staff minion, and an Explosive Trap and Frost Hydra active, against a target that has been Oiled (due to the Explosive Trap), and within the range of the Dryad's aura in a Master Mode world with all bosses defeated.
