Debuffs

**Debuffs** are temporary, negative status effects, as opposed to buffs, which affect the player positively. Once a debuff has been inflicted, the debuff's icon will display to the  upper right /  upper left of the player's window, along with a  icon shading /  count-down timer, showing how much longer the debuff will be in effect.  The counter will begin at one minute/second less than its listed duration and show zero during the final minute/second.

Most debuffs can only be inflicted by enemies, however it is also possible for traps and Red Potion to inflict some debuffs on players.

Players can inflict various debuffs on most enemies. See Notes for a list of weapons that inflict debuffs on enemies.

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 Venom do not stack, and Poisoned will take precedence over Venom. Death always cancels any active buffs or debuffs.

Unlike buffs, debuffs cannot be canceled by right-clicking their icons. The Nurse can cancel debuffs at a cost of 750 per active debuff. This does not apply to the Potion Sickness debuff, because when trying to cancel the Potion Sickness debuff, the Nurse will not charge for recovery of the debuff and the debuff will not be canceled, but the Potion Sickness icon will disappear.

## Notes

* Players with the Darkness debuff will keep their eyes shut as a cosmetic indicator.
* The duration of the following debuffs, if inflicted on players, is increased by 100% in Expert Mode (i.e. doubled) and by 150% in Master Mode:

* Poisoned
* Darkness
* Cursed
* On Fire!
* Bleeding
* Confused
* Slow
* Weak
* Silenced
* Broken Armor
* Cursed Inferno
* Frostburn
* Chilled
* Frozen
* Ichor
* Acid Venom
* Blackout

* Furthermore, players in Expert worlds are inflicted with the Chilled debuff when they enter water in a Snow biome. The Chilled debuff lasts for as long as the player is in the water and lasts for 5 seconds after getting out.

* The maximum possible damage per second that can be inflicted on an enemy with damaging debuffs is 1331. This can be achieved by consuming a Flask of Cursed Flames, switching between wearing Frost armor and Huntress armor/Red Riding armor and a Magma Stone, and using the Daybreak, Bone Javelin, Shadowflame Knife, Venom Staff, while having a Imp Staff, a Hornet Staff, a Stardust Cell Staff minion , and a Explosive Trap sentry summons active, against a target that has been Oiled (due to the explosive trap) and within the range of Dryad's aura in a world with all bosses defeated.
* The following weapons inflict debuffs on enemies:
