Corrupted Items Guide in Patch 8.3: Vision of N'Zoth. (BfA 8.3)

Individual Corruption effects are sold directly by MOTHER in the Chamber of the Heart in Silithus for Echoes of Ny'alotha as items called Preserved Contaminants.

These allow for specific Corruption effects (and the associated Corruption penalty) to be applied to a selected item. The inventory of available Preserved Contaminants will change twice a week with Assault resets to cycle through all available Corruption effects at various levels of potency. You can use Preserved Contaminants to apply the Corruption you purchased to any uncorrupted item that can be Corrupted, just like enchants.

Items touched by N'Zoth's influence grant great power, but expose bearers to dangers of increasing severity.

Gear from all sources in Patch 8.3 except for Azerite Armor and Trinkets slots has a chance to drop as Corrupted and each Corrupted item comes with:

• A purple primary Corruption stat, which activates negative effects at certain thresholds based on the character's Total Corruption level;
• A desirable on-equip effect;

Gear from Horrific Visions always corrupts as of March 17, 2020.

Individual pieces of Corrupted Gear add some Corruption toward your character's Total Corruption count. On top of that, Corrupted Items also come with desirable on-equip effects and negative effects that activate at various thresholds based on your Total Corruption level.

You can build up Corruption Resistance through various means in Visions of N'Zoth, preventing the negative effects from activating.

With Corrupted Items, your main goal is to reduce your Total Corruption level while maintaining the beneficial on-equip effect on your Corrupted Gear.

Below, we explain the most important terms related to Corrupted Items in more detail.

Corrupted Items in Patch 8.3 come with a purple Corruption stat which indicates that an item is Corrupted.

Items with the Corruption stat roll in three tiers, with corresponding on-equip effects, except for a few outliers. The higher the tier, the more Corruption an item will have and the more powerful the on-equip effect will be. We distinguish between three types of on-equip effects: passives, procs, and unique effects.

• Type 1: Passives — Roll with +10, +15, or +20 Corruption
  • Passive on-equip effects that increase your secondary and tertiary stats by a percentage belong here;
• Type 2: Procs — Roll with +15, +20, or +35 Corruption (except for a few outliers)
  • Various procs that increase your Critical Strike / Haste / Mastery / Versatility are included in this category;
• Type 3: Unique Effects — The effects have variable Corruption ranges;
  • Comprised of diverse and very powerful unique procs.

You can find a list of the effects in our on-equip effects section below.

Base Corruption is the sum total of your Corruption on all your currently equipped gear.

There are various ways to build up resistance against Corruption in Visions of N'Zoth, mainly through Wrathion's Legendary Cloak and Patch 8.3 Essences.

Your Total Corruption is simply your Base Corruption minus your Corruption Resistance. At various Total Corruption thresholds, negative effects will activate and bad things will happen to you. See our negative effects section below.

Corrupted Items roll with one random beneficial on-equip effect which can come in three tiers. The higher the tier, the stronger the on-equip effect, and the more Corruption the item will have. You can cleanse Corrupted Items (including weapons), but note that they will lose both the desirable on-equip effect, as well as Corruption. Corruption effects do stack if you have the same effect on more than one item, but the duration of procs does not increase. On-equip effects include passives, procs, and unique effects.

The first type of on-equip effects passively increase your secondary and tertiary stats by a flat percentage. These effects come in three tiers that roll with 10, 15, or 20 Corruption respectively, whereas the tier of the effect depends on the Corruption value rolled. If you have an item with +20 Corruption and the Severe effect for example, it is of Tier 3 and the amount of Critical Strike you gain from all sources will be increased by 12%.

• Avoidant (10 / 15 / 20 Corruption) — Your Avoidance is increased by 5 / 8 / 10% of your Haste.
• Masterful (10 / 15 / 20 Corruption) — Increases the amount of Mastery you gain from all sources by 8 / 12 / 16%.
• Severe (10 / 15 / 20 Corruption) — Increases the amount of Critical Strike you gain from all sources by 6 / 9 / 12%.
• Expedient (10 / 15 / 20 Corruption) — Increases the amount of Haste you gain from all sources by 6 / 9 / 12%.
• Siphoner (17 / 28 / 45 Corruption) — Increases your Leech by 2 / 5 / 8%.
• Strikethrough (10 / 15 / 20 Corruption) — Increases the damage and healing you deal with Critical Strikes by 2 / 3 / 4%.
• Versatile (10 / 15 / 20 Corruption) — Increases the amount of Versatility you gain from all sources by 6 / 9 / 12%.

The second type of on-equip effects comes in the form of various procs. The vast majority of the effects rolls with 15, 20, or 35 Corruption depending on the tier with a few exceptions.

• Deadly Momentum (15 / 20 / 35 Corruption) — Your Critical hits have a chance to increase your Critical Strike by 31 / 41 / 72 for 30 sec, stacking up to 5 times.
• Honed Mind (15 / 20 / 35 Corruption) — Your spells and abilities have a chance to increase your Mastery by 392 / 523 / 915 for 10 sec.

• Surging Vitality (15 / 20 / 35 Corruption) — Taking damage has a chance to increase your Versatility by 312 / 416 / 728 for 20 sec.

Glimpse of Clarity and Gushing Wound always roll with 15 Corruption and the effects have just one tier, instead of the usual three tiers. The Ineffable Truth effect rolls in two tiers with either 12 or 30 Corruption.

• Glimpse of Clarity (15 Corruption) — Your spells and abilities have a chance to grant you a Glimpse of Clarity, reducing the cooldown of your next 1 spell cast by 3 sec.
• Gushing Wound (15 Corruption) — Your damaging spells and abilities have a chance to cause your target to ooze blood, dealing [70% of Attack Power or 70% of Spell Power] damage over 7 sec.
• Ineffable Truth (12 / 30 Corruption) — Your spells and abilities have a chance to show you the Ineffable Truth, increasing the rate your cooldowns recover by 30 / 50% for 10 sec.

The third and final type of Corruption effects comes in the form of unique effects. These have various Corruption ranges, depending on the power of the effect and can roll in three tiers as highlighted below.

• Echoing Void (25 / 35 / 60 Corruption) — Your damaging abilities build the Echoing Void. Each time it builds, Echoing Void has a chance to collapse, dealing 0.4 / 0.6 / 1% of your Health as Shadow damage to all nearby enemies every 1 sec until no stacks remain.
• Infinite Stars (20 / 50 / 75 Corruption) — Your spells and abilities have a chance to strike a nearby enemy with an Infinite Star, dealing 111 / 276 / 415 [Attack Power or Spell Power] Arcane damage and increasing their damage taken from your Infinite Stars by 25%, stacking up to 10 times.
• Twilight Devastation (25 / 50 / 75 Corruption) — Your attacks have a chance to trigger a beam of Twilight Devastation, dealing damage equal to 6 / 12 / 18% of your Health to all enemies in front of you.
• Twisted Appendage (10 / 35 / 66 Corruption) — Your attacks have a chance to spawn a tentacle which Mind Flays your target for [ 25 / 45 / 65% of Attack Power or 25 / 45 / 65% of Spell Power ] Shadow damage every second for 10 sec.
• Void Ritual (15 / 35 / 66 Corruption) — Gain Void Ritual, giving your spells and abilities a chance to increase all secondary stats by 14 / 33 / 63 every sec for 20 sec. This chance is increased if at least 2 nearby allies also have Void Ritual.

On top of having positive on-equip effects, Corrupted Items come with negative side effects and your goal is to reduce your Total Corruption by building up Corruption Resistance to reduce the amount of negative side effects active at any given time. It is important to note, however, that cleansing Corrupted Items removes both the Corruption stat and the On Equip effect (see our cleansing corrupted items section).

Here is a list of all the side effects with a description of what exactly they will do to your character and how much Total Corruption is required to trigger them.

• Grasping Tendrils (1 Corruption) — Taking damage has a chance to reduce your movement speed by 5 sec. The magnitude of the snare increases with further Corruption.
• Eye of Corruption (20 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.
• Grand Delusions (40 Corruption) — Taking damage has a chance to summon a Thing from Beyond, which pursues you for 8 sec. Its speed increases with further Corruption.
• Cascading Disaster (60 Corruption) — If you are struck by the Thing from Beyond, you will be immediately afflicted by Grasping Tendrils and Eye of Corruption.
• Inevitable Doom (80+ Corruption) — All damage taken is magnified and healing received is reduced, increasing with further Corruption.
• Inescapable Consequences (200+ Corruption) — Taking 25% of maximum Health as damage every second while in combat.

Here we have the Corrupted Items user interface as portrayed in the game. It contains all important information including Base Corruption, Corruption Resistance, Total Corruption, and the currently active negative effects with the next inactive effect greyed out.

From the moment you obtain your first Corrupted Item, you will receive the Curious Corruption instruction quest and must visit MOTHER who teaches you how to purify Corrupted Items.

Cleansing a Corrupted Item costs 5 Corrupted Mementos and removes the On Equip and Corruption from a Corrupted item.

There are various ways to increase your Corruption Resistance in Visions of N'Zoth.

• Ashjra'kamas, Shroud of Resolve (Wrathion's Legendary Cloak) comes with a baseline +Corruption Resistance stat which increases with each rank. At Rank 15, it has 50 Corruption Resistance and you can start collecting Malefic Cores to further increase your Corruption Resistance by 3 each time up to a maximum of 125 Corruption Resistance.
• Minor Powers of the new Patch 8.3 Essences decrease your Corruption by 10. The effect does not stack, so if you have two Minor Powers of the new Essences equipped, your Corruption Resistance will still be 10, not 20.

All weapons acquired in Visions of N'Zoth have a chance to roll with Corruption and on-equip effects. Certain weapons from Ny'alotha come with fixed on-equip effects. You can cleanse them just like Corrupted Items.
