The questline to obtain the Green Fire spell effect for your Fire spells was added to the game several expansions ago, yet it is still tied to one single character.
I wouldn’t mind it too much if the questline wasn’t unnecessarily long, and also of practically zero difficulty which makes it nothing but a grind and a chore. I have done it on two different characters so far and I do not feel like running through it a third time.
Isn’t it time to finally make this option account-wide at this point? After making every race being able to be Warlocks and adding a bunch of new customization options for your demons, now seems like a great time to adjust this.
