It’s a poor mans ammo regen
Edit: On another note, since Moze is really proficient with grenades. I’ve been looking at some of these artifacts recently and i can see a lot of synergies with the Fish Slap. Cut Purse is the obvious one but there’s also the elemental Stones (+80% bonus damage), Planetoid (+75% bonus Damage after melee), and then White Elephant (Stickies). Anyone mess around with these?
