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 #956DD1 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.

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.

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.

Corrupted items can be purified by MOTHER, removing both benefit and corruption. Purification costs and requires completion of 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 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:

• 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.
• The Eye of Corruption can be obtained as a companion pet.
• The Heart of Darkness (Azerite trait) Azerite trait will only function if you have 25 or more corruption (prior to patch 9.0.1).
