WITCH Demon glitch - Spirit from gear inconsistently calculated, preventing transformation

Hi all,

I discovered a bug, if you have spirit from an amulet or body armor the game is very inconsistent with how it calculates this for your transformation. The matter is made more complicated if you have multiple spirit using passives. I tested it with having undead out and multiple passives and got multiple results based on order, what support gems I had and other factors.

If you have a skill with stages such as undead minions then you will lose all minions on transformation then have an appropriate number respawn.

If you have a spirit with multiple individual allotments such as blasphemy where it takes 60 per curse you have applied then it will shut down completely.

The order of the skills 100% matters because if you have an undead before a passive then it will summon one undead instead of keep the passive up.

Finally, and most game-breakingly if you only have spirit passives and the amount of spirit you would have before calculating chest and amulet slot isn't enough for everything then you are unable to transform period and are locked out of the ability.

The way to replicate this is to have a witch with demonic transformation, equip with a body that has +34 spirit, an amulet with +15 spirit, and I completed the act 1-3 things that give spirit. I have demonic form with herbalism support stone, grim feast with no support stones, and Blasphemy with Despair and Clarity attached. If you attempt to transform you won't be able to. If you move the Herbalism gem from demonic form to grim feast then you can transform but GF will be turned off. If you remove Herbalism from GF it will turn back on, and then you can put herbalism back into GF to gain the benefits of all stones.

Doing this I have 10 spirit left while in demon form with all of these passives active, but due to how the system calculates things I'm unable to transform into this state, only cheat it in by removing a stone and adding it back in after transforming.

This is also the case with all persistent buffs granted by Ascendancies (for example: Temporal Rift)

This bug essentially makes support gems cost double, but the incorrect "extra" cost doesn't show up in tooltips.

It will work correctly if you remove all spirit-costing support gems from Demon Form. Instead, put them in your other persistent buffs granted by gems - this is the only workaround that I know of, and it does use valuable support gem sockets.
