Since Zeus was only a half formed idea I can't say they were exactly the same but there similarities are such that it is probably best I think up something else.

The backstory I had for the weapons was that Sapphire's main weapon which I have yet to design was created specifically for her by her father who is a famous hunter. Sapphire is very skilled with the weapon but she can't stand to actually use it and only does so in desperate situations. Instead she uses the daggers that belonged to her mother which are intended as side weapons. She might have a third melee weapon that she uses in place if the one her father designed but it would be something pretty simple, likely no dust capabilities and only one form.
