Patch 12.1 “Curse of Ula’tek” · PTR build 68569

Datamined changes Numbers pulled straight from the game files of the next PTR build, cross-checked against Blizzard’s official notes.

Datamined, not confirmed. Everything on this page comes from PTR build 68569 game files, not from Blizzard’s Development Notes. Datamined tooltip values are real data, but they are work-in-progress: some are placeholders, some get reverted, and bug-fix / description-only edits are easy to misread. The official, higher-confidence numbers live on the main breakdown and tier sets pages. This page is kept separate on purpose. Every percentage below is computed in code from the datamined old→new values, never hand-typed.

1. The datamining checks out

datamined vs official

The strongest reason to trust this build: where it overlaps the official Week 3 notes, the datamined tooltip coefficients reproduce Blizzard’s stated percentages exactly. Frost Death Knight is the clearest case - the raw attack-power coefficients in the files compute to the same numbers Blizzard published.

SpecAbilityDatamined coefficientComputed changeOfficial Week 3
Frost DKIcy Death Torrent215.424% → 140.026% AP-35%-35%
Frost DKRemorseless Winter18.066% → 12.6462% AP-30%-30%
Frost DKObliterate88.8308% → 79.9477% AP-10%-10%

When the files and the notes agree to three decimal places, the datamining method is sound - so the datamined-only findings below are worth reading, with the caveat that they have not been written into official notes.

2. Headline datamined findings

not yet in official notes

The biggest structural changes in build 68569 are design edits, not just number tweaks:

Datamined Evoker

Scalecommander Wingleader reworked

The hero talent that reduces Breath-spell cooldowns was heavily cut. Devastation’s Bombardments now reduce Deep Breath by 0.5 sec per target struck, capped at 1.5 sec; Preservation / Augmentation’s Mass Eruption reduces Breath of Eons by 1.0 sec per target, capped at 3.0 sec. Previously uncapped - a large nerf to Breath uptime.

Datamined Paladin

Protection talent tree reorganized

The Protection Paladin talent tree layout was rearranged in this build. A structural change to talent positioning rather than a raw damage number, so no single percentage - but it changes what builds are reachable.

Datamined All classes

A big wave of tier-set tuning

This build touched many Season 2 class sets - values, redesigns, and a fully rebuilt Blood DK set. The confirmed designs are on the tier sets page; the datamined numeric tuning is in section 4 below.

3. Datamined spec-wide damage tuning

class aura old → new

Several specs have a single “Modifies Damage/Healing Done” class aura that scales all their damage. Build 68569 shifts these. The effective change is the ratio of the new multiplier to the old one - e.g. a +41% aura going to +46% is 1.46 / 1.41 = +3.5% to everything the aura touches. These are datamined and may not match the final official notes.

SpecClass-aura valueEffective all-damage change
Devourer Demon Hunter+10% → +21%+10%
Balance Druid+41% → +46%+3.5%
Havoc Demon Hunter+22% → +16%-4.9%
Unholy Death Knight-20% → -26%-7.5%
Frost Death Knight-2% → -12%-10.2%

Two single-ability buffs sit outside the table because they hit one spell, not the whole kit: Marksmanship Hunter’s Black Arrow (direct damage +20% → +50%, +25% effective; damage-over-time +50% → +87%, +24.7% effective), and Mistweaver Monk’s Spinning Crane Kick aura (+166% → +193%, +10.2% effective - a small change in practice, since Mistweaver is a healer and SCK is a minor part of its output).

4. Datamined tier-set tuning

5. Why datamined is not final

read before quoting these

Datamined values are a snapshot of a build in progress: internal test values, placeholders, and numbers that get re-tuned before release. Unholy Death Knight shows exactly how much a number can move - and it is a change Blizzard has already documented, so we can compare directly:

Unholy DK. Unholy is nerfed hard in Blizzard’s official Week 3 notes - a spec-wide “all damage” cut plus a stack of individual ability nerfs. Blizzard first posted that spec-wide cut at -8%, then hotfixed it to -3% after a bug had skewed the tuning. This datamined build shows its own spec-wide damage aura (the -20% → -26% line in section 3) and a new -25% Death Coil modifier - values that do not line up with that final -3%. Same direction (Unholy is getting nerfed), very different magnitude.

That is the whole point: even Blizzard’s official number moved five points via hotfix, so a raw datamined value is a work-in-progress reading, not final tuning. Rule of thumb: trust this page most where it agrees with the official notes (section 1), treat datamined-only numbers (sections 2-4) as strong signal, not gospel, and expect specifics to move before 12.1 ships.
