In case anyone didn't see, I decided to do away with the "crystals forged into weapons" bit. At least, it won't count against your Elemental total.

You could still forge some of yours into a weapon, but the elements used will still count toward your elemental ratio. For instance, a Monk might make a staff, but it will count as part of their raiment. It's purely an aesthetic choice, what shape your Raiment takes.
