It would be nice to enhance builds by using something like d1 artifact for extra mods we can't fit, no ammo or flinch mods, more like some combat mods and the elemental mods from the gauntlet helmet and class items, plus orb mods. Should have maybe have 4 or 3 slots and have mix element affinity, maybe limited to 2 affinity and more cost on the slots for the mods
