[Adept]

He doesn't have gift of health cast, and the player in question is absolutely convinced something like this happens when he hits dominion 10.

It may be he's confusing it with something, but it sounds like something one should check out. It's early age T'ien Ch'i. I don't remember if their mages are sacred.

/edit
Easy enough to check in solo play, but I've been too busy to check it out.
