Recently, I've been encountering a problem with critical damage/healing. It isn't doing as much as it should! Using the 400 health pixie spell, getting a critical should give me an 800 health return. With my bonus to incoming healing, it should be healing me for about 940 health. When I got this to happen in-game, however, I only healed for 636 health, less than what it should have. Does anyone know what the cause of this is?
