I know THAT, but I read that if you have some damage but still get overhealed you get 0 mana back. So if you're at 9K/10K health, and you get healed for 2K, that would be 1K of heal plus overheal, are you going to get 100 mana or 0 mana?
(Answer I'm looking for is in the form of "100 mana" or "0 mana" in direct response to the question).
