The Coming Calamity Support Gem Issue

The Coming Calamity Support Gem Issue
Summary of the Problem

Players are experiencing significant issues when trying to use support gems with the herald skills granted by The Coming Calamity Heroic Armour in Path of Exile 2. The main problems reported include:

Inability to socket support gems into the heralds provided by the armour, with the game stating "support gem does not work with this skill".

Attribute requirements may prevent support gems from being socketed or functioning correctly, even if the herald skill is active.

Attempting to socket certain support gems (e.g., into Herald of Ice) can cause the game to crash instantly.

Support gems may disappear or duplicate, and sometimes the entire armour piece vanishes temporarily when entering a map or portal.

Logging out and back in may restore the armour, but missing support gems are often permanently lost.

Possible Causes
Attribute Requirements: Not meeting the attribute requirements for a support gem can prevent it from being used, even if the herald skill appears active.

Game Bugs: There are widespread bugs affecting both the herald skills and support gems, leading to crashes, item disappearance, and gem loss.

Developer Status
As of April 2025, these issues appear to be unresolved and are causing significant frustration in the community. Players are advised to exercise caution when using The Coming Calamity with support gems, and to report any bugs to the official forums.

Workarounds
Ensure all attribute requirements for support gems are met before socketing them.

If items or gems disappear, try restarting the game to recover missing items, though lost support gems may not return.

Avoid socketing support gems into heralds if you encounter crashes or item loss, until a fix is released.

Additional Notes
The Coming Calamity is intended to allow heralds to be linked to support gems without increasing their reservation cost, but current bugs are preventing this from functioning as intended in Path of Exile 2

Any updates on this?

Hi there at around 2am GMT I was playing poe2 and in my hide out and i have been trading to get gear to make a build using the coming calamity along with triple heralds.
i just finished the set up put all my support gems in the build and i had a sale come up on the right hand side for stash tabs so went to look at that and brought the 10 coin prem tab update.
Came off and went im going to go for a run so looked for a map put it in and went to the map and the build wasnt working well thats when I cam back and find its not on my person the support gems are in my storage and i no longer have the chest piece in my possession as if it was removed from game.


Following this I done the usual IT thing and turned it off and on again and my chest was back on yet my gems were not socketed and i was missing support gems that i had just brought and found i had a double ambush when i know i only had the one.

i have done my build again and ran the dungeon with this build but for some reason when I go to do some skills such as wind serpent it comes up on screen with a notification saying failed to parse item if the problem persists please report it.

so i can confirm that a lot of this is still happening at this point of time and that i have logged in this morning with once again items missing and chest not there and sup gems slotted back into the chest but having deleted ones that i have socketed.

Addtionally, the bug can be replicated by adding two curse reduction runes into the chest piece. It causes the chest to disappear on entering a map and to reappear on login without the socketed runes.
