Obtaining a corrupted item.

Corrupted items are gear that has been corrupted by N'Zoth. During Battle for Azeroth Season 4, many items have a chance to be corrupted when they're received, which grants them a bonus effect and a certain amount of the corruption stat. As a character's total corruption increases, they suffer increasingly detrimental effects. Corruption also affects a character's appearance, gradually covering their body in a shimmering purple miasma. At a corruption level above 80, the miasma will turn red.

Corruption effects

Every corrupted item will have one of the following properties. The corruption effect on an item, along with its power level and associated corruption, is determined at random. MOTHER in the Chamber of Heart sells Preserved Contaminants on a rotating basis that can be used to give items specific corruption effects.

Certain weapons from Ny'alotha, the Waking City always "roll" the same corruption effect every time they drop. Some of them have a unique effect that cannot be obtained on any other item; these are listed at the bottom of the table below.

The Eye of Corruption.

The Thing From Beyond. Its appearance is a reflection of the player's.

Wearing corrupted items raises the level of base corruption, which can be offset by the resistance provided by equipping and upgrading  [Ashjra'kamas, Shroud of Resolve]. The resulting net total corruption causes harmful effects described in the table below.

Name Begins at Effect
Spell priest voidtendrils.png Grasping Tendrils
Taking damage has a chance to reduce your movement speed for 5 sec. The magnitude of the snare increases with further Corruption.
Inv eyeofnzothpet.png Eye of Corruption
Your spells and abilities have a chance to summon an Eye of Corruption for 8 sec. The Eye inflicts increasing Shadow damage to you every 2 sec while you remain in range.

Range and damage increase with further Corruption.

Ability deathwing assualtaspects.png Grand Delusions
Taking damage has a chance to summon a Thing From Beyond, which pursues you for 8 sec. Its speed increases with further Corruption.
Inv eyeofnzothpet.png Cascading Disaster
If you are struck by the Thing From Beyond, you will be immediately afflicted by Grasping Tendrils and Eye of Corruption.
Inv eyeofnzothpet.png Inevitable Doom
All damage taken is magnified and healing received is reduced, increasing with further Corruption.
Achievement nzothraid nzoth.png Inescapable Consequences
N'Zoth lays claim to your very essence, dealing 25% of your maximum health every 1 sec while you are in combat. The end is nigh.


MOTHER's purification UI.

Corrupted items can be purified by MOTHER, removing both benefit and corruption. Purification costs 5 Corrupted Mementos and requires completion of N [120] Curious Corruption, which starts automatically upon obtaining a corrupted item for the first time. A corrupted item that has been purified can be re-corrupted by using a Preserved Contaminant purchased from MOTHER.

On the PTR

Removed from game The subject of this section did not make it out of the PTR stages of patch 8.3.0.

On the patch 8.3.0 PTR, "corruptions" were found on rings sold by the Heartzertauren, perhaps as an alternate concept for the system or simply a way to test the effects. While Thing From Beyond made it to live as a consequence with minor changes and Last Grasp may have inspired Grasping Tendrils, all of the others were scrapped. These include:

Name Effect
Ability creature cursed 03.png Face the Truth An eldritch scroll spawns near you that you and others with this corruption can see. Each second you don't face it, it deals damage to you. If it deals damage to you 5 times, you are feared for 6 sec.
Ability creature cursed 03.png Masochistic When you fall below 25% health, taunt all nearby enemies for 5 sec.
Ability warlock soulswap.png Mesmerizing Your damaging spells and abilities against a repeated target reduce your movement speed by 5% for 6 sec, stacking up to 10 times.
Ability creature cursed 03.png Overconfident When you receive overhealing, you refuse the next (Total health*1/4) Healing within 10 sec.
Warrior disruptingshout.png Revel in Violence Your killing blows cause you to revel in violence, rooting you for 6 sec.
Ability creature cursed 03.png Spontaneous Fury Periodically marks a random enemy, making them the target of your fury. While your fury persists, your damage against all other foes is reduced by 10%.

Notes and trivia

  • Inescapable Consequences was added after a player named Rextroy won several 2v2 arena battles despite wearing 675 corruption. He completed this feat as a protection paladin, using immunities while waiting for 27 ranks of Infinite Stars to one shot most opponents.[1][2]
  • The Eye of Corruption can be obtained as a companion pet.
  • The [Heart of Darkness] Azerite trait will only function if you have 25 or more corruption (prior to patch 9.0.1).

Patch changes

  • Shadowlands Patch 9.0.1 (2020-10-13): Effects disabled.
  • Battle for Azeroth Hotfix (2020-07-09): Players with a Corruption level of 200 or higher will now receive an additional negative effect, Inescapable Consequences, which deals 25% of your maximum health in damage every second while you are in combat.
Developers' note: While Corruption's damage taken and healing received debuffs are substantial at high Corruption amounts, players possessed of particular ingenuity have constructed strategies allowing them to deal nearly infinite damage during brief windows when they themselves are immune to damage. It's important to us that players feel like they can play around with how much Corruption they can afford to wear, but we're setting a hard limit at 200 Corruption – going beyond that, N'Zoth's dark power will defeat you.
