Battle for Azeroth Discipline Priest Guide - Corruption

Corruption is a new system that has been added in Patch 8.3 Visions of N'zoth and replaces Titanforging. In this guide, you will learn everything you need to know about the Discipline Priest Corruptions, which to take advantage of, which to avoid, and how much Corruption is too much to handle.

What is Corruption?

Corruption is a new system of power progression which replaces Titanforging; instead of item level bonuses, they will now have a chance to be Corrupted by the Old Gods, represented by the purple-colored stat which adds both a positive effect and stacking negative attribute which incurs penalties at various thresholds. Although the negative effects can reach a point at which they become debilitating, carefully managing the bonuses and penalties allows for a great deal of customization and individual power gain.

Corrupted gear can be freely cleansed by M.O.T.H.E.R. in order to remove both effects and revert them back into normal items, however, corruption cannot be added to items, so care should be taken before removing potentially useful bonuses. Corruption resistance can also be gained over time, both from new minor essences, and the legendary cloak Ashjra'kamas, Shroud of Resolve, allowing more corrupted effects to be worn. For more information on all potential Corruptions, see Wowhead's Corruption Overview Guide.

Buying Corruptions with Echoes of Ny'alotha for Discipline Priest

What Corruptions should I Buy from MOTHER on a Discipline Priest?

Corruptions now can be purchased from MOTHER using Echoes of Ny'alotha. Every few days, a new set of Corruptions will be accessible.

With that in mind, we present a list of the best corruptions to purchase from MOTHER.

For Raid/Throughput
  • Expedient - Your first on the buy list, general top builds are involving haste in some manner. Some builds focus on pure haste, others mix haste with other stat amplifiers like Severe.
  • Ineffable Truth - Rank 1 is more efficient. There is heavy variance in top performing logs with some opting to run Ineffable and others preferring heavy stat synergy. If you do run ineffable you likely only need a small amount and would not stack it.
  • Severe - Ideally, take a look at what options you already have at your disposal and build a synergistic set around it. You don't want to stack BOTH Severe and Versatile but instead take into account what you already have and build around that. If you choose Severe you can also gem/enchant around it, same with Versatile.
  • Versatile - For stat amps, look to take R3 when possible.

About Siphoner - While Leech is extremely strong raw throughput, now that you can apply corruption to any piece you will want to apply corruption to pieces that already have tertiary leech on them so you can use your corruption budget for other options. Low ranks of Siphoner can be useful for filling out your corruption budget, but again not as efficient compared to applying corruption to pieces with tertiary (natural) leech on them.

For Dungeons/Damage
  • Gushing Wound - Despite the nerf it still is consistent damage that is easy to utilize in a 5man environment.
  • Twilight Devastation - Strongest potential damage corruption but relative proximity to melee requirements has its risks and is not always easy/feasible in dungeons.
  • Twisted Appendage - Not as consistent of damage delivery as Gushing Wound but not range requirements like Twilight Devastation make this more of a middle of the road option.

Best Disc Priest Corruption Bonuses

Top Effects

Discipline Priests look to generally prioritize cooldown reduction or leech effects for maximum healing. While Siphoner seems to be the highest throughput at present, Ineffable Truth is also excellent for greater throughput and access to your cooldowns.

Passive Effects
  • Siphoner — Increased Leech is always incredibly beneficial for Discipline, especially in progression and especially when encounters favor heavy "rot" ticking damage. Expect this to be a very high throughput increase.
Proc Effects

he above corruption effects all passively increase the value of your secondaries. While these corruption effects all give procs of secondary stats. Secondary stats overall aren't far from each other in value and any of these proc effects are quite good.

  • Ineffable Truth — This corruption effect is actually a weapon effect that can be applied to many different pieces. While in early progression many ramp windows are set in stone, this corruption gets better as fights accelerate and you want to have your cooldowns back more rapidly.
  • Void Ritual — A weapon corrupted effect that can corrupt other pieces of gear. This corruption price will often be high but looks to be quite potent, especially if other allies share it as well.
  • Infinite Stars — While recently nerfed they are Infinite so nerfing infinity is still infinity. This is a damage focused corruption that does NOT proc Atonement healing. All the same, it is still incredibly good damage that can benefit your raid or M+ runs massively.
  • Deadly Momentum — Increased Crit strike proc.
  • Racing Pulse — Increased Haste proc.
  • Surging Vitality — Increased Versatility proc.
  • Honed Mind — Increased Mastery proc.
  • Expedient — To assist in Haste reaching a sufficient level (many stick to the mid/high 20s region but there is no specific breakpoint) this corruption piece can work well with providing additional secondaries.
  • Severe — Similarly, if you receive sufficient Haste and want to move more towards Crit to work with Strikethrough, then this corrupted piece can assist as well.
  • Masterful — While Mastery is not a weak stat by any means its value with this passive effect depends entirely on how much of this stat is naturally present on your gear.
  • Versatile — Similar to the Mastery effect, Versatility is not a poor stat by any means and might be even more crucial if encounters require greater damage reduction in order to survive incoming hits.
Passive Effects
  • Avoidant — Avoidance seems incredibly situational but could have specific areas where it shines for surviving a particularly challenging boss encounter in raids or Mythic+.

Discipline Priest Ny'alotha Weapons

Besides random corruption effects, weapons from the new Ny'alotha raid also have exclusive effects on them, which can be quite powerful. Similar to random corruption effects, if you obtain a weapon with a subpar effect, you can always cleanse it. As a Discipline Priest, you can obtain weapons with the following effects:

  • Vorzz Yoq'al: always comes with Void Ritual - It looks to be the ideal weapon for the raw secondary stats that it can provide and relatively lower level of corruption. Both of these effects can also be placed on other weapons or items in or out of the raid so keep that in mind.
    +35 Corruption
  • Eyestalk of Il'gynoth: always comes with Ineffable Truth - which is pretty powerful as well, but can also be rolled on random pieces of gear.
    +50 Corruption

Vorzz Yoq'al looks to be the ideal weapon for the raw secondary stats that it can provide and relatively lower level of corruption. Both of these effects can also be placed on other weapons or items in or out of the raid so keep that in mind.

Corruption Bonuses

While there are a few items with guaranteed specific corrupted effects, the majority are randomly determined when the item drops. Most corruption affix has multiple tiers which scale both the positive effect and the amount of negative corruption stat gained; for example, an item may randomly roll with Tier 1 Strikethrough which adds +10 to the Corruption stat, or Tier 3 Strikethrough and +20 to the Corruption stat, which is twice as strong at the cost of twice as much corruption.

The corruptions listed below are separated into two types - those which give passive bonuses, and those which are proc based.

Passive corruptions, as hinted by its name, are effects that are always active while wearing the corruption piece. Albeit usually weaker than Proc Corruptions, Passive corruption effects have a cheaper Corruption cost to their proc counterparts.

  • Strikethrough — Increases the damage and healing you deal with Critical Strikes by 2%/3%/4%. Adds +10/+15/+20 Corruption.
  • Avoidant — Your Avoidance is increased by an amount equal to 5%/8%/10% of your Haste. Adds +10/+15/+20 Corruption.
  • Severe — Increases the amount of Critical Strike you gain from all sources by 6%/9%/12%. Adds +10/+15/+20 Corruption.
  • Expedient — Increases the amount of Haste you gain from all sources by 6%/9%/12%. Adds +10/+15/+20 Corruption.
  • Masterful — Increases the amount of Mastery you gain from all sources by 6%/9%/12%. Adds +10/+15/+20 Corruption.
  • Versatile — Increases the amount of Versatility you gain from all sources by 6%/9%/12%. Adds +10/+15/+20 Corruption.

Proc based corruptions are more varied than the statistical ones, both in terms of benefit and the amount of corruption gained for each effect at each tier, some of which are not currently known to us. Tuning should be expected for many of these effects.

  • Devour Vitality — Your auto-attacks have a 25% chance to bite into the target's soul, dealing 2% of your health in damage and healing you for that amount. +25 Corruption

  • Ineffable Truth — 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. +25/+50 Corruption

  • Echoing Void — Your damaging abilities build the Echoing Void. Each time it builds, Echoing Void has a chance to collapse, dealing 1%/1.5%/2.5% of your Health as Shadow damage to all nearby enemies every 1 sec until no stacks remain. +15/+25/+50 Corruption
  • Infinite Stars — Your spells and abilities have a chance to strike a nearby enemy with an Infinite Star, dealing 60%/80%/100% Attack power or Spell power Arcane damage and increasing their damage taken from your Infinite Stars by 25%, stacking up to 10 times. +25/+50/+75 Corruption
  • Twisted Appendage — Your attacks have a chance to spawn a tentacle which Mind Flays your target for 25%/45%/65% Attack power or Spell power Shadow damage every second for 10 sec. +15/+35/+66 Corruption
Stat Procs
  • Void Ritual — Gain Void Ritual, giving your spells and abilities a chance to increase all secondary stats by 7/10/13 every sec for 20 sec. This chance is increased if at least 2 nearby allies also have Void Ritual. +15/+35/+66 Corruption
  • Deadly Momentum — Your critical hits have a chance to increase your Critical Strike by 31/41/72 for 15 sec, stacking up to 5 times. +15/+20/+35 Corruption

Dealing With Negative Effects of Corruption

In addition to the bonuses, corrupted items also increase the Corrupted stat by varying amounts based on the tier of the effect. Corruption stat incurs penalties that the player must deal with, and while these effects start out rather benign, they quickly ramp up in both potency and impact, to the point where it can be very hard to deal with during a Dungeon or Raid encounter, and even become outright debilitating at the highest levels.

There are five effects unlocked at different total corruption levels:

At Rank 6, the legendary Cloak Ashjra'kamas, Shroud of Resolve gains an on-use effect which will remove and immune all currently active negative corruption effects.

Discipline Priest Corruption Tips

  • Grasping Tendrils — Dispel :)
  • Eye of Corruption — the range will vary in size depending on your corruption level and it is imperative that you must move out of it as quick as you can. Always work to have at least one Angelic Feather available in case you need to quickly move out of harm's way.
  • Grand Delusions — Thing from Beyond can be knocked back by Shining Force but you must make sure you're not knocking any other enemy mobs mid-boss fight as that can have negative effects on the team during progression.
  • Cascading Disaster — At 60 Corruption the Thing From Beyond moves very quickly and you should either have your Shining Force ready and your head on a swivel or be ready to dispel rapidly. Utilizing the Sanctum trait can be very helpful for an emergency defensive when at high corruption.

How Much Corruption Should a Discipline Priest Take?

Corruption looks to be a difficult mechanic to set one value to for every encounter. Instead, it looks like corruption will fluctuate on progression depending on the potential mechanics or incoming damage that you must deal with. While many of the negative side effects can be dispelled or healed through, encounters can vary heavily in the constraints and a poorly timed negative corruption effect can kill. It is recommended that you bring minimal corruption into a new encounter as you learn your role in the encounter, then steadily add corrupted pieces as comfort dictates.

During progression many wipes will occur to plain mechanical failures, attention or focus loss. Adding a death to corruption is unnecessary and often risky to the team's goal of progression. Staying below 40 corruption to start can be very beneficial to avoid any unexpected burst of damage early on, then deciding if moving up to ~59 corruption is worth dealing with being chased should be made after that. Only on easily rekillable bosses or desperate enrage timers should going over 80 corruption be considered.
