[@Akayaofthemoon] Hey, I hate to be the guy that ruins everyone's character but Nightmare technically has two weapons, dual-wielding is still two and the only gem to dual wield so far is Garnet and we both know about her. 

Note: The only reason I bring this up is because I was going to make fusions of everyone and I realized that it is very hard to fuse two swords with someone's one weapon into one bigger weapon
