The quest [Disruption - Forge Camp: Mageddon] has you kill 10 Gan’arg Servants, who cast Power Burn (https://www.wowhead.com/spell=32003/power-burn#comments), this spell is currently bugged and instead of dealing 10% mana drain and damage, it is dealing 922% which one shots my level 58 character every time.
In the wowhead comments there is another player facing the same issue, so it is not just me.
confirmed to still be an issue in 10.2. The named forgefiend mob in the Honor Hold Mine uses it to, and he hit me for over 20k at level 57 with it today
This is still bugged, but it seems like a pretty simple bug.
It’s supposed to take 10% of your mana, and hit you for that amount as damage, according to Wowhead.
My feral has 30,850 mana, which means 3,085 damage, right? Nope.
The in game tooltip says “consumes up to 3,085% mana.” Percent! And then returns that as damage… which comes up to an insane amount.
So it should be 10% mana consumed, OR 3,085 mana consumed, but not 3,085% mana consumed. An extra percentage got thrown into the formula.
