[@Lugubrious] If she does a little bit of damage to enemies, she gets a little bit of healing back. It's relative to her own health, not the health of her enemies. So if she steps on a bug or something and totally kills it, she won't get anything back. But in the game if you walk up to a bad guy and he's hitting her with bullets and she's shooting him with bullets, she can kind of match that DPS with her healing per second. And the crystals drop on the ground where the bad guy gets hit, so she has to walk over and get within a few feet in order to get the healing benefits. 

Okay let me try to sum it up instead of being dumb. If she shoots a dude with a bullet, the amount of healing dropped will be a little less than the damage of the bullet she fired.
