Tier Set Adjustments Unveiled in 10.2 PTR Build 51425 - Numerous Alterations

Key Takeaways

• PTR Build 51425 for Patch 10.2 Guardians of the Dream was a numeric tuning pass — it adjusted ability values, not the fundamental mechanics of each set.
• Notable number shifts in this build: Frost DK 4pc proc chance dropped from 40% to 30%; Resto Shaman Tidal Reservoir healing share dropped from 20% to 15%; Prot Paladin Fire-damage chance increased from 20% to 40%; Guardian Druid Blazing Thorns reflection increased from 10% to 100%.
• The "106 seconds" Empower Rune Weapon cooldown value that appeared in datamine strings was a raw placeholder — the intended live value was 10 seconds.
• All bonuses below reflect the Build 51425 PTR state, which served as the base for final tuning before the November 7, 2023 launch.
• This is historical Dragonflight content. The Amirdrassil sets have since been superseded by later expansions.

Here is the full class-by-class breakdown of what the Amirdrassil tier set bonuses looked like in PTR Build 51425, with each spec's correct 2pc and 4pc described.

What Was PTR Build 51425?

PTR Build 51425 landed in September 2023, roughly six weeks before Patch 10.2 went live. The build represented a tuning sweep across nearly every Amirdrassil tier set — Blizzard adjusted the numeric values on existing mechanics without changing which abilities the sets interacted with. The datamined diff was substantial enough that Wowhead and MMO-Champion covered it as a dedicated news item, giving players a look at where the power levels were landing before class tuning moved on to live adjustments.

The raw datamine strings in this build also contained a placeholder value of "106 seconds" for the Frost Death Knight 4pc's Empower Rune Weapon cooldown reduction. That figure was an internal spell-data artifact; the intended value was 10 seconds, which is what went to live.

Death Knight Tier Set

Blood Death Knight

2pc: Consuming Runic Power has a chance to cause your next Heart Strike to apply Ashen Decay, reducing damage dealt to you by 10% and increasing your damage dealt to afflicted targets by 20% for 8 seconds.

4pc: Soul Reaper's execute damage and Abomination Limb's damage applies Ashen Decay to enemy targets. Heart Strike and Blood Boil's direct damage extends Ashen Decay's duration by 1 second.

Frost Death Knight

2pc: Chill Streak's range is increased by 4 yards and it can bounce off of you. Each time Chill Streak bounces, your damage is increased by 4% for 10 seconds, stacking up to 5 times.

4pc: Chill Streak can bounce 2 additional times. Each time it bounces, you have a 30% chance to gain a Rune, reduce Chill Streak's cooldown by 5 seconds, or reduce the cooldown of Empower Rune Weapon by 10 seconds. (Build 51425 lowered this proc chance from 40% to 30%.)

Demon Hunter Tier Set

Vengeance Demon Hunter

2pc: When you attack a target afflicted by Sigil of Flame, your damage and healing are increased by 2% and your Stamina is increased by 2% for 8 seconds, stacking up to 5 times.

4pc: Sigil of Flame's periodic damage has a chance to flare up, shattering an additional Soul Fragment from a target and dealing additional damage. Each 40 Fury you spend reduces Sigil of Flame's cooldown by 1.0 second.

Druid Tier Set

Guardian Druid

2pc: Rage you spend during Rage of the Sleeper fuels the growth of Dream Thorns, absorbing 25% of damage dealt to you.

4pc: Each 40 Rage spent while Rage of the Sleeper is active extends its duration by 1.0 second (up to a maximum of 5.0 seconds). Dream Thorns become Blazing Thorns that reflect 100% of absorbed damage back at the attacker. (Build 51425 increased this reflection from 10% to 100%.)

Mage Tier Set

Arcane Mage

2pc: Consuming Clearcasting grants 2% increased spell damage for 20 seconds, stacking up to 10 times. (Build 51425 extended the duration from 15 seconds to 20 seconds.)

4pc: After consuming Clearcasting 3 times, your next Arcane Missiles becomes Arcane Battery, dealing 150% increased damage to your primary target and firing at up to 4 nearby enemies for 100% increased damage.

Fire Mage

2pc: When Pyroblast and Flamestrike critically strike, you gain Searing Rage, increasing your critical strike damage by 4% for 12 seconds, stacking up to 20 times. (Build 51425 raised the per-stack bonus from 3% to 4%.)

4pc: Activating Combustion increases the critical strike damage bonus of Searing Rage by 150% for 12 seconds. (Build 51425 raised this from 100% to 150%.)

Monk Tier Set

Windwalker Monk

2pc: Melee attacks have a chance to make your next Spinning Crane Kick free. Free Spinning Crane Kicks grant Blackout Reinforcement, increasing the damage of your next Blackout Kick by 150%. (Build 51425 raised this from 100% to 150%.)

4pc: Blackout Reinforcement-empowered Blackout Kicks reduce the cooldown of Fists of Fury, Rising Sun Kick, and Strike of the Windlord by 2.0 seconds. (Build 51425 raised this from 1.0 second to 2.0 seconds.)

Paladin Tier Set

Protection Paladin

2pc: Judgment grants a stack of Sanctification, reducing your damage taken by 2.0% per stack. Upon reaching 5 stacks, your Consecration becomes empowered.

4pc: While within an empowered Consecration, your abilities have a 40% chance to deal bonus damage or healing as Fire. (Build 51425 raised this chance from 20% to 40%.)

Retribution Paladin

2pc: Expurgation lasts 3 additional seconds and deals 30% increased damage. Casting Judgment or Divine Toll triggers Wrathful Sanction, dealing Holy damage to the target and resonating additional Holy damage to nearby enemies.

4pc: Wrathful Sanction grants Echoes of Wrath, causing your next Templar's Verdict or Divine Storm to strike twice, with the second hit dealing 25% effectiveness. (Build 51425 lowered the second hit from 50% to 25%.)

Rogue Tier Set

Assassination Rogue

2pc: Each 10 Energy you spend grants Natureblight, increasing your attack speed by 1% and your Nature damage dealt by 1% for 6 seconds, stacking up to 5 times.

4pc: Envenom additionally triggers an Envenomous Explosion, dealing Nature damage to all enemies within 8 yards.

Shaman Tier Set

Elemental Shaman

2pc: Primordial Wave also casts an Elemental Blast at the target at 70% effectiveness and grants you all three Elemental Blast bonus effects for 10 seconds.

4pc: Lava Burst burns the target for 10% additional damage over 4 seconds. After consuming Primordial Wave, your next 3 Lava Bursts also strike up to 3 additional targets affected by Flame Shock for 100% of normal damage.

Restoration Shaman

2pc: Chain Heal, Healing Surge, and Healing Wave mark their initial target with Tidal Reservoir, causing that target to receive 15% of all Riptide healing you deal for 15 seconds. (Build 51425 reduced the healing share from 20% to 15% and extended the duration from 10 to 15 seconds.)

4pc: Riptide's healing is increased by 20%. If Riptide is active on the same target as Tidal Reservoir, its heal-over-time has a 5% chance to create a new Riptide on a nearby ally. (Build 51425 reduced this proc chance from 10% to 5%.)

Warlock Tier Set

Affliction Warlock

2pc: Soul Rot deals 15% increased damage and lasts 4 additional seconds.

4pc: Soul Rot grants 3 Umbrafire Kindling, enhancing your next Malefic Rapture to deal 50% increased damage or your next Seed of Corruption to deal 60% increased damage.

Warrior Tier Set

Protection Warrior

2pc: Spending Rage has a chance to cause your next Shield Slam to consume your bleeds on a target, instantly dealing 40% of their remaining damage and reducing your damage taken by 10% for 5 seconds.

4pc: For each bleed effect consumed, your damage taken is further reduced by 2%. Shield Slam bleed consumption also reduces the cooldown of Thunderous Roar by 3.0 seconds.

Frequently Asked Questions

What did PTR Build 51425 change about the Amirdrassil tier sets?

Build 51425 was a numeric tuning pass. It adjusted values such as proc chances, damage percentages, and cooldown reductions, but did not change which abilities each tier set interacted with. The most significant changes were the Frost DK proc chance reduction, the Guardian Druid reflection increase from 10% to 100%, and the Fire Mage crit damage bonus increase.

Why did the Frost DK 4pc show "106 seconds" in datamine tools?

That figure was a raw internal spell-data placeholder string in Build 51425, not an intended game value. The actual cooldown reduction for Empower Rune Weapon was 10 seconds, which is what shipped to live.

Are the Amirdrassil tier sets still relevant in 2026?

No. The Amirdrassil sets were Dragonflight Season 3 content (November 2023). They were superseded by The War Within tier sets and are now historical content. The raid can still be cleared for transmog purposes in Patch 12.0.5 (WoW Midnight).

Were the PTR values the same as what launched on live?

Mostly, but not exactly. Some specs saw additional adjustments between Build 51425 and the November 7, 2023 live launch. The Windwalker Monk 4pc cooldown reduction, for example, was further tuned during the PTR period. Build 51425 represented a meaningful snapshot, not the final shipped state.

Which class saw the biggest change in Build 51425?

Guardian Druid arguably saw the most dramatic single-value change: the Blazing Thorns damage reflection went from 10% to 100%, effectively making the 4pc a full reflect of all absorbed damage. Prot Paladin's Fire-damage chance doubling from 20% to 40% was also impactful for the spec's throughput.
