On the text description for Dark Apotheosis it is listen that “Soulshatter becomes Provocation which taunts your target, Twilight Ward becomes Fury Ward which will absorb all schools of damage, Shadow Bolt becomes Demonic Slash, and Fear becomes Sleep.” It is not listed that Fel Flame becomes Void Ray but this is the case.
If it is not listed as one of the abilities that need to change then why does it change? This has to be a bug as during pre-patch when using Dark Apotheosis Fel Flame was still an available spell to use but ever since post pre-patch this has not been the case.
I dont understand why suddenly this move is being changed when entering Dark Apotheosis form and i believe it needs to be fixed ASAP as i love experimenting in MMOs with unique playstyles and builds but this has been a hinderance on the experience.
Without Fel Flame the Dark Apotheosis form loses out on a secondary way to generate demonic fury with only Demonic Slash being a reliable way to generate Demonic Fury (Corruption also generates fury but doesnt add enough to really impact the Demonic Fury Starvation that can happen).
On top of all this the move that Fel Flame turns into becomes absolutely useless towards the Dark Apotheosis form as it doesnt do any more damage because of the form and just becomes a dead move that is literally never uses when in Dark Apotheosis as it does less damage than every other spell and eats Demonic Fury up.
TLDR; Currently when entering Dark Apotheosis form the move Fel Flame turns into Void Ray which it didnt do in pre-patch and is also not listed in the abilities that are suppose to change. This creates resource starvation and gives the form a dead spell that is never used.
How to fix?
Simply just make Fel Flame usable in Dark Apotheosis form like it was in pre-patch.
