Incomplete List

This is not a comprehensive list and may be missing some changes, for example, undocumented hotfixes, PvP changes or uninteresting bug fixes.

Patch 12.1.5 was released on Oct 13, 2026.

Spell Changes

Change Holy Celerity and Ultimate Serenity have swapped positions on the specialization tree. Blizzard's Developers' notes:

Ultimate Serenity is a powerful tool for Holy priests, specifically in M+. We are moving it up in the talent tree to reduce the amount of investment required for Holy priests to take it so that it enables more choice amongst talents beyond the second gate.

Below is a list of things that are suspected to be bugs or unintended behaviour.

Tested 12.1.5.70783 Twist of Fate does not always trigger from healing events. This happens most often if the person healed below 30% is healed well beyond 35% very quickly.
Tested 12.1.0.69111 Twins of the Sun Priestess does not trigger during Spirit of Redemption.
Prayer of Healing casts consuming Surge of Light when talented into Spiritwell and Ultimate Serenity reduces the cooldown of Holy Word: Serenity by 12 seconds, not 10.
Tested 12.1.0.69497 Divine Hymn sometimes ticks for 5-10x more than it should.
Tested 12.1.5.70783 Divine Image can be bugged so it only despawns if you cast an empowered Naaru, or move 100 yards away.
Requires Testing Casting Flash Heal or Prayer of Healing and then mid-cast if you gain Surge of Light from Halo, when the cast completes you do not consume Surge of Light, but do get a mana discount.
Tested 12.1.5.70783 Halo will miss targets that are too close to you on the return from Divine Halos. See this github issue.

Tested 12.1.5.70783 Ultimate Serenity can't be talented into while any charges of Holy Word: Sanctify are on cooldown.

Tested 12.1.0.69497 2-set bonus 2pc does not grant any visible bonus. This is intended, as it functions off a whitelist and isn't a global crit increase.
Tested 12.1.0.69497 Binding Heals also triggers Protective Light on yourself regardless of your Flash Heal target.
Tested 12.1.0.69497 Evoker's Blessing of the Bronze which affects a movement enhancing ability for all classes, affects Leap of Faith for Priest.
Tested 12.1.0.69497 Evoker's Time Spiral which affects a movement enhancing ability for all classes, affects Leap of Faith for Priest.
Tested 12.1.0.69497 Light of the Naaru CDR increase is not reflected in any ability tooltips.
The following spells no longer trigger Echo of Light:
- Tested 12.1.0.69497 Dispersing Light
- Tested 12.1.0.69497 Trail of Light
- Tested 12.1.0.69497 Binding Heals
- Tested 12.1.0.69497 Desperate Prayer
