it seems like both the normal one and pump-charge projectiles don't count as you actually killing a mob meaning they don't drop exp on death and also meaning the bloodshed enchant doesn't do anything when they kill something

I was able to get shotgun-fist to aggro mobs, so this issue is sort of half-fixed now. I'll still need to implement kill-credit itself

this is because the projectile's damage does not credit it to the player, doing so causes the bullet to deal knockback which is bad lol, I have no clue why the game behaves this way but I will look into finding alternative ways of giving kill-credit
