There’s a bug for Diabolist speced Destruction Warlocks that affects incinerate (if it’s macroed). When you summon a Maiden of Pain with Demonic Art, it transforms your incinerate into Fel Bolt. However, it prevents you from casting incinerate if you have it on a macro.
This is clearly not intentional since no other modifier in the game does this. Whether a spell modifier buffs or changes the nature of said spell, this shouldn’t happen and does not happen with other spell.
Please fix.
