I'm starting to love this Enhancement. Tried it out in several places, but am really noticing it in Shroud. As the Cleric, I've got my eyes glues to health bars during 4-5, and the HP of the person I was targeting for HC didn't move. And it wasn't lag- he saw the same thing. I think it was the increase in saves, but can't be sure until I go through a few more Shrouds.

Tested also- Non-dispellable by Beholders.
