Earthen Beads, Rak'shor's cunning ghoul

[Chattius]

I turned my adventurer from dwarf to ghoul with the Rak'shor cunning prodigy. I was curious if the healing from Earthen Beads would be working. I can heal others but not me. The bug is that the cooldown is reset but no fizzle or not working message given.

The talent specifically says that the heal doesn't work on undead.
