Okay, good to know.
So, in theory, I could create a new projectile that only affects the player and allies, yeah? And then make that projectile heal instead of do damage. It'd actually be kinda neat to kill an enemy and have a soulstone-like projectile make its way back to the player in order to heal them. Almost like snatching up that enemy's lifeforce or something. Which actually would be much cooler than what I had planned... IF it is doable anyway.
