it cant go completely empty (exept after use perhaps) since the reveal states that it will drain to a cap of something like perhaps 5% of his max hp when he is out of battle. It will definitly have a cd, it could have been one of the most op passives in the game otherwise.

but we dont actually know anything yet, so both our assumptions coulc be wrong.
