Encountered this a couple of weeks ago. I didn't see it posted in the bugs forum. As alluded to in the Battle Log within the image attached, the Priest plays [Consuming Touch] on a Goblin Berserker that held [Raging Strike], and the goblin received the extra damage from rage, but the Priest (Melcarcan) didn't receive any return HP.
He was at full health already. After the attack he takes 3 damage from a clumsy chop, leaving him at 17/20.
