Diablo 4’s Warlock is built around forcing demons to fight other demons.
Aspect of Reanimation is supposed to make summons stronger the longer they remain alive.
There is only one problem.
Player testing suggests the Aspect currently does absolutely nothing for Warlock Demon summons.
The demons appear. They attack. The damage remains exactly the same.
Apparently even Hell has discovered unpaid labour.
Aspect Of Reanimation Shows No Damage Increase
The original bug report appeared in May 2026 and focused on Fiend of Abaddon.
The player reported that Aspect of Reanimation had zero visible effect on the summon’s damage.
The report became active again on July 24 after another player performed a more controlled test.
They removed their normal equipment and replaced it with plain Level 70 items.
The only meaningful item was a two-handed weapon carrying Aspect of Reanimation.
They then compared multiple casts with the Aspect equipped against casts using an ordinary grey weapon.
The reported damage was identical.
Not slightly lower than expected.
Not inconsistent.
The same.
The Test Included Two Different Demon Skills
The latest test did not rely on one summon.
The player used both Fiend of Abaddon and Command Fallen.
Fiend of Abaddon summons a massive demon that remains active for a duration and attacks nearby enemies.
Command Fallen summons a Fallen Lunatic that charges a target and explodes.
The tester specifically used the longer-lasting Fallen Rush version, allowing the summon to remain active long enough for Reanimation’s scaling effect to become visible.
Both abilities lasted approximately 30 seconds during the test.
Neither showed a noticeable damage increase from Aspect of Reanimation.
The Aspect had enough time to wake up.
It simply chose not to attend.
Hellbent Commander Worked As A Control
The strongest part of the report is the control test.
After testing Reanimation, the player equipped another two-handed weapon carrying Hellbent Commander.
That Aspect correctly increased the damage of both tested Demon summons.
This matters because it suggests Warlock summons are capable of receiving external summon-related bonuses.
The skills themselves are not completely isolated from Legendary Aspects.
One summon Aspect works.
Reanimation apparently does not.
That makes the problem look less like inaccurate observation and more like one specific effect failing to recognise Warlock demons.
Reanimation Was Originally A Necromancer Aspect
Aspect of Reanimation has historically been associated with Necromancer Minions.
Its effect rewards summons for remaining alive by gradually increasing their damage.
Blizzard previously expanded the Aspect to affect Necromancer Golems as well as Skeletons.
With the arrival of the Warlock, the game now contains another class built heavily around summoned creatures.
The likely issue is that Warlock Demon summons may not carry the exact internal tags the Aspect expects.
That has not been confirmed by Blizzard.
But Diablo 4 has a long history of effects working only when the correct Skill, Minion or Summon tags are inherited properly.
If the Aspect still checks specifically for Necromancer-style Minions, Warlock demons may be standing directly outside the definition.
Warlock Demons Are Central To The Class
This is not a minor interaction involving one novelty skill.
The Warlock’s entire class identity revolves around summoning and controlling demons.
Blizzard describes the class as a visceral caster that uses demons as weapons while managing Wrath and Dominance.
Warlock skills summon Fallen, tortured creatures, massive fiends, demonic hands, floating eyes and other deeply unhealthy workplace relationships.
The class mechanic also binds specific Greater Demons through Soul Shards.
Summon damage is therefore not a niche stat.
For several Warlock archetypes, it is the build.
The Aspect Sounds Perfect For Long-Duration Summons
Aspect of Reanimation should naturally fit summons that remain active for an extended period.
Fiend of Abaddon is an obvious example.
The demon stays on the battlefield and repeatedly attacks enemies.
An effect that increases summon damage over time should reward the player for keeping that demon active.
Command Fallen variants with longer durations should benefit for the same reason.
Instead, current testing suggests the Aspect occupies an equipment slot without contributing damage.
The tooltip promises a scaling summon bonus.
The demon receives a motivational poster.
A Dead Aspect Can Ruin An Entire Build Test
Legendary Aspect slots are expensive.
Equipping Reanimation means not using another offensive effect.
On a two-handed weapon, the opportunity cost becomes even larger because offensive Aspect values are normally amplified.
A player may sacrifice a powerful working multiplier because Reanimation appears perfect for a summon build.
If the effect contributes nothing, the build can perform dramatically worse than expected.
The player may then blame the summon, the skill tree or the class itself.
In reality, one equipped Aspect may simply be decorative.
This is why silent damage bugs are particularly damaging.
The game does not display an error.
It lets the player continue building around a number that never arrives.
Tooltips Do Not Reveal Which Summons Qualify
The issue also exposes a larger clarity problem.
Diablo 4 uses several overlapping terms:
- Minions
- Summons
- Demon summons
- Lesser Demons
- Greater Demons
- Temporary summoned creatures
Those categories may look similar to players while functioning very differently inside the game.
An Aspect that says it affects summons may not necessarily affect every creature created by a skill.
If Reanimation is intentionally restricted to Necromancer Minions, the tooltip and Codex should say so clearly.
If it is intended to work for Warlock demons, the current behaviour needs fixing.
Either way, players should not need grey gear and repeated training tests to discover which definition Blizzard selected.
Other Warlock Summon Effects Already Work
The successful Hellbent Commander test is important because it demonstrates that Blizzard has already connected at least some summon effects to Warlock demons.
Frenzied Onslaught has also been reported to increase summon attack speed correctly.
That means the class is not universally broken when interacting with external summon bonuses.
The inconsistency is narrower.
Some effects recognise the demons.
Aspect of Reanimation apparently looks directly at them and sees office furniture.
The Bug May Affect More Than Two Skills
The controlled test focused on Fiend of Abaddon and Command Fallen.
The Warlock has many other Demonology skills that could potentially be affected.
These include Tortured Wretch, Wall of Agony, Rampage, Profane Sentinel and several Soul Shard summons.
There is not enough public testing to confirm that Reanimation fails on every Warlock demon.
The current evidence proves only that the tested skills showed no visible benefit.
Still, if the underlying problem is a missing tag or class restriction, other Demon summons may fail for the same reason.
Warlock players using Reanimation should test their specific setup rather than assuming the Aspect works because the tooltip appears compatible.
Players Can Test The Aspect With Basic Gear
The cleanest community test is similar to the one already reported.
- Remove equipment containing unrelated damage bonuses.
- Equip basic items with consistent stats.
- Use a plain weapon and record summon damage.
- Equip an equivalent weapon carrying Aspect of Reanimation.
- Allow the same summon to remain active for the full duration.
- Compare repeated attacks against the same enemy or training target.
A summon should deal more damage after remaining active long enough to build the Reanimation bonus.
If the numbers remain identical across repeated casts, the Aspect is probably not contributing.
Players should avoid testing during crowded Helltides or large events.
Too many buffs, enemy modifiers and other players can make the results impossible to read.
For once, the demons need a quiet laboratory.
Warlock Players Should Use A Different Aspect For Now
Until Blizzard confirms or fixes the interaction, Warlock summon builds may be better served by an Aspect with a visibly working effect.
Hellbent Commander is the clearest alternative mentioned in player testing.
Frenzied Onslaught may also provide a measurable summon benefit depending on the build.
The correct replacement will depend on the specific Demon skills and equipment slots available.
The important part is not continuing to sacrifice a major offensive slot for an effect that may provide zero damage.
Reanimation can return when it remembers the Warlock exists.
Blizzard Has Fixed Reanimation Before
Aspect of Reanimation has required corrections in previous Diablo 4 patches.
Blizzard previously fixed interactions where the Aspect failed to increase damage from effects connected to Necromancer Minions.
That history shows the Aspect’s damage application has been fragile before.
The Warlock adds an entirely new summon ecosystem with different skills, resources and internal creature types.
It would not be surprising if the old Aspect did not automatically recognise every new demon.
That does not make the bug acceptable.
It does make it believable.
The Current Patch Notes Do Not Include A Fix
Blizzard’s July 14 patch includes several Warlock fixes.
The update corrected problems involving Brutal Aspect, Fulcrum of Mefis and Flesh of Abaddon.
It does not mention Aspect of Reanimation failing on Demon summons.
The July 24 player test suggests the problem remains active after that patch.
Blizzard has not publicly confirmed the bug, its scope or an expected fix date.
Until that happens, the community evidence remains the best available warning.
This Needs More Than A Tooltip Change
If Reanimation is intended to work with Warlock demons, Blizzard needs to repair the actual damage calculation.
Adding the correct summon tags may be enough.
The developers should then test short-duration and long-duration demons separately.
Temporary summons, Soul Shard demons and persistent Greater Demons may all use different internal systems.
The fix should also confirm that the bonus ramps correctly over time rather than applying its maximum value immediately or failing after a recast.
Warlock summon builds have enough moving parts already.
The damage bonus should not become another demon requiring exorcism.
Summon Builds Need Reliable Rules
Warlock players need to know which effects strengthen their demons.
That sounds obvious.
It becomes surprisingly complicated when the game treats Minions, Summons and Demonology creatures as different categories without clearly explaining the borders.
Aspect of Reanimation should either work for compatible Warlock demons or clearly state that it does not.
The current situation does neither.
The Aspect appears usable.
The damage stays unchanged.
The player loses an equipment slot and spends an evening wondering why the build feels weak.

The Warlock can summon Hell’s most violent creatures and bend them to their will.
Making Aspect of Reanimation acknowledge them is apparently the harder ritual.
