Plenty of enemies have been made to use as minion summons, but what about weapons? A couple simple ones came to my mind.
Archer Staff: Summons a magic Platinum-tier bow that floats within your vicinity, firing normal arrows (without gravitational falloff) at enemies. Wielding a bow will give control over the summon(s), allowing them to fire when you fire (as rapidly as a Platinum Bow allows), as well as in the direction you fire, and even use the ammo that your bow is using.
Gunslinger Staff: Same mechanics as the Archer Staff, but with a Handgun and Musket Balls.
