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 Holy 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.
Best Holy Priest Corruption Bonuses
One of the top Corruption effects to prioritize seems to be the boost to Critical Strike damage and healing Strikethrough for progression healing. Eternal Palace demonstrated how important healer damage can be and while Holy does not have amazing passive damage, it can further increase it while increasing their healing with this effect. While Strikethrough seems to be the ideal corruption effect at present, others on this tab are also quite good.Passive Effects
- Strikethrough — As mentioned above, healer damage is always very important during progression and Holy Priests will likely have sufficient Mastery to start moving towrds more Crit in Ny'alotha.
- Siphoner — Increased Leech is always incredibly beneficial for healers, especially in progression and especially when encounters favor heavy "rot" ticking damage. Expect this to be a very high throughput increase.
- Masterful — Mastery is often the best secondary for early progression healing and if you have heavy levels of it on your gear, you will get strong value from the secondary increase.
- Severe — Holy already moves more towards Crit in the latter part of the expansion so increasing your secondaries naturally can also help your synergy with Strikethrough.
The 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.
- 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. All the same, it is still incredibly good damage that can benefit your raid or M+ runs massively.
- Ineffable Truth — This corruption effect is a weapon effect that can be applied to many different pieces. This effect could be exceedingly powerful for the spec if the damage is consistent enough to make constant use of low-cooldown Holy Words.
- Deadly Momentum — Increased Crit strike proc.
- Surging Vitality — Increased Versatility proc. Some potential of issue if there isn't sufficient damage to proc this.
- Honed Mind — Increased Mastery proc.
- Versatile — 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. Value will be determined by the quantity of Versatility on the player's gear.
- Glimpse of Clarity — Cooldown reduction for Holy seems very interesting since the only abilities we use with cooldowns we are heavily incentivized to reduce (Holy Words/Circle). This may be stronger than just the "moderate" rank that it falls in at the moment but needs more testing to truly gauge the value.[
- Avoidant — Avoidance seems incredibly situational but could have specific areas where it shines for surviving a particularly challenging boss encounter in raids or Mythic+.
- Expedient — Haste is less than ideal for Holy Priests so if the player isn't having much Haste on their gear as is, they won't gain many secondaries from this effect.
- Racing Pulse — Increased Haste proc again isn't ideal for the spec so this proc is on the low end of a priority.
Holy 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 Holy 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.
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.
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.

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:
- Grasping Tendrils — Unlocked with 1 Corruption
- Eye of Corruption — Unlocked with 20 Corruption
- Grand Delusions — Unlocked with 40 Corruption
- Cascading Disaster — Unlocked with 60 Corruption
- Inevitable Doom — Unlocked with 80 Corruption
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.
Holy 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 Holy 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.
