Yes, I'm aware that the revenants use necrofire to respawn. The bug is in the way necrofire is spread to varying heights on rubble, stairs, etc. Such necrofire will not clear -even if repeatedly targeted - that is "fringes on higher elevations remain even though they were contiguous. Furthermore, subsequent bless casts on the "fringe necrofire" DO NOT CLEAR IT even though the tool tip for the surface clearly displays "necrofire." So Flipping ANNOYING.
I must say that you need to rethink this entire mechanic. Loosen up on what ground effects are contiguous when there are varying elevations involved. I am so annoyed right now.
Love you guys, but you really pissed me off with this revenant necrofire bless fiasco.
