So reading the patch notes today:
Was wondering if Signet of Undeath was on the list of possible tuning?
I cannot tell you how many times I have gone to cast this and the target either teleports out of it or is finished before it completes casting. That said, whether it "actually" works or not, it takes your health regardless.
Would be amazing if, when there was no target available to resurrect, it would just fizzle/cancel the skill.
Thanks!
