Blasphemy Bug

Hi,POE2 Support Team,

First I need to apology for my english grammar and phrasing. I try to use AI to fix grammar and phrasing so I can report this bug properly. I hope you notice this bug, which is causing bad experiences for some players.

Bug Summary:
The Blasphemy Support gem frequently deactivates on its own. When this happens, the aura effect vanishes, the reserved spirit is returned, and the skill slot shows a "Missing socketed skill" error. The skill also becomes deselected from its assigned weapon sets in the skill bar configuration.

Character Information:
Character Name: DekNevermore
Class / Ascendancy: Witch / Lich
Date First Encountered: September 3, 2025
Relevant Skill Information:
Primary Gem: Blasphemy (Level 14)
Linked Gems: Any curse skill gem (e.g., Despair, Temporal Chains, etc.)

Steps to Reproduce (Inconsistent):
The bug does not have a single, reliable trigger but occurs under the

following conditions:
- Socket a curse gem linked with Blasphemy Support.
- Activate the aura. It will function correctly for an indeterminate amount of time.
- The bug can occur spontaneously during gameplay or after specific actions like weapon swapping or changing areas.

Expected Result:
The Blasphemy aura should remain active, reserve Spirit, and apply its linked curse to nearby enemies as long as it is enabled and the character has sufficient Spirit.

Actual Result:
The Blasphemy aura visual effect disappears, and the reserved Spirit is refunded.

The skill slot for the aura displays the error message "Missing socketed skill."

In the skill assignment UI, the checkboxes for Weapon Set I and Weapon Set II for the Blasphemy skill become unchecked.

Attempting to reactivate the skill by re-checking the boxes causes the visual to appear for a few seconds without reserving Spirit or applying the curse before disappearing again.

Additional Observations & Troubleshooting:

Weapon Swapping: Sometimes triggers a 1-2 second window where the aura functions correctly before failing again.

Replacing Gem: Using a completely new Blasphemy gem provides a temporary fix, but the new gem will eventually fail in the same manner.

Leveling Gem: Leveling up the Blasphemy gem does not resolve the issue.

Weapon Set for socketed gem: Set Curse Gem to Weapon Set I and Weapon Set II does not resolve the issue.

Thank you for making amazing game
Looking forward to support and enjoy POE2

hope this helps demonstrate the same issue a lot of us are having with the gem

I experienced the same issue yesterday. After the problem occurred, I realized it might be because I added Clarity I Support to Blasphemy, even though I already had Clarity II on my Bloodmage's Ascension Spirit skill. Or maybe it's due to the latest update.

I can't do more tests — I don't want to risk bricking my last spirit gem

same

Thats fking unplayable now without curses...

it's harsh if you don't have an extra uncut spirit gem lying around =/

after some testing, this is caused by putting Heightened Curse into the blasphemy gem. A blasphemy gem that has ever had this support is then bricked.

Very harsh if you've put quality on the blasphemy gem, please fix

Same here.
