What in the world...?!?
When you’re downed and use vapor form, when it wears off it “reapplies” whatever health you were missing while downed.
So if you’re a tick away from dying or something and mist, then it wears off, you’ll see it “hit” you for big damage in the log. It’s just putting you back at the hps you were before you misted though.
14k damage from vapor form?!?
It will almost always be the highest damage in your death log if you mist formed while downed.
