He's a maker mage, it should be expected that he is well versed in many weapons. Besides, most of the weapons are just advanced variations of the basic forms of his weapons. I mean look at Gray, he uses many forms of weapons made of ice.

Yes he does use many different weapons made from his magic but a lot of those, conjuring then weapon is the attack itself and then it's gone. He's not wielding most of those like what it seems with your spells. Zeroths idea works to cut down the number of Spells cause I will admit that was what was nagging at me is the redundancy of listing all the different kinds of swords. So it comes down to is he actually wielding this weapon or is it just for one attack? If that makes senee.
