Shadow Flare needs a new effect.

[Edellis]

Shadow flare has a nice animation and it covers a wide range, but it's near useless when it comes to battle. To the normal enemies it's fine the damage is barely noticeable, but at least the slow effect works until you get to the boss, then it becomes a unless ability. I haven't ran pass T5, so I don't know if it works in SCoB or FCoB. Would it be broke if Shadow flare had a weak version of vulnerability up?

any amount of passive damage is better than none. Especially if it's a long duration DOT that requires no real input from you after casting. This is why most off-GCD abilities do low damage, they add alot more damage overall than you think.
