Debuffs are a feature first introduced in patch 1.0.6. Debuffs bestow negative effects upon their bearers, and unlike Buffs, cannot be removed by right-clicking on their icons. There are several accessories which provide immunity to a single Debuff, which build into the Ankh Charm, giving immunity to many debuffs. Some Monsters can be infected with certain debuffs, including Confused, Cursed Inferno, On Fire! and Poisoned.

Debuffs will naturally wear off after a short period of time, though some may last up to a few minutes. The Nurse can cure debuffs at the cost of 7 SilverCoin Small 50 CopperCoin Small per debuff.

In 1.2, many new accessories were added which prevent one specific debuff each, and can be combined at a Tinkerer's Workshop to create versions that give immunity to all the debuffs of their components.

  1. 1.0 1.1 Debuff nullified by running
  2. This debuff works identically to the Oozed Debuff, therefore it is possible that Dazed was planned to be added in the place of Oozed, but was cut by unknown reasons.
  3. The following monsters can inflict the On Fire! debuff: Fire Imp (Burning Sphere), Lava Slime, Meteor Head, Skeleton Archer (Flaming Arrows)
  4. The following weapons can inflict the On Fire! debuff: Fiery Greatsword, Flamarang, Flamelash, Flamethrower, Flaming Arrow, Flower of Fire, Molten Fury, Molten Hamaxe, Molten Pickaxe, Sunfury
  5. These items will only give protection against the On Fire! debuff inflicted by Lava, as well as lava damage. They will not protect against the debuff from other sources.
  6. The following weapons can inflict the Poisoned debuff: Blade of Grass, Poisoned Knife, Thorn Chakram, Tonbogiri.
  7. The following healing items will inflict the Potion Sickness debuff: Bottled Water, Glowing Mushroom, Goldfish, Greater Healing Potion, Healing Potion, Lesser Healing Potion, Lesser Restoration Potion, Mushroom, Restoration Potion
  8. Apparently, the Sugar Rush Debuff was planned to be inflicted by the cut Slice of Cake item.
  9. Withered armor can stack with Broken Armor. However, instead of completely removing the player's defense (50+50=100% Armor reduction) it will instead lower the defense by 75%. This is because they won't trigger on the same time, so first it will inflict a 50% armor reduction, then another 50% on the remaining defense value. (i.e: 50 Defense - 50% = 25 - 50% = 12.5 (Rounded down to 12)).

Bugs

  • When curing the Potion Sickness debuff via the Nurse, the icon disappears but the actual effects of the debuff are not removed.
  • The Bleeding effect can be overridden by the Campfire effect and various accessories.
  • On the 3DS version, the Mana Sickness Debuff does not occur when the player drinks a mana potion, allowing for unlimited mana.
  • On the 3DS version, the Broken Armor Debuff can last to over 10 minutes.
