It's not just a toolbox and an ammo pouch, it's an aetherotransformer, a magitecknical gizmo that makes your bullets from your body's aether, so without that, you have no bullets (basically you're firing 'magic bullets' of aether and not real ones made of metal and propelled by gunpowder or a similar explosive), and that lore is still current even with certain abilities that also drew on it's lore being removed.
