What happened?

When playing around with Mahou Tsukai i put special interest in the "Projection" spell, which makes a copy of "any" tool that is in your offhand / first slot, after testing it out i found that it also copies the enchantments and apotheosis gems.

So if you put a perfect gem(s) / perfect enchantment(s) on any tool and then copied it, you can then use any disenchanter (i used corail tombstone as it was cheapest in books) to get all the enchantments without losing them on the first one (or lose the new tool), additionally you can after that put it in a smithing table with a Vial that removes the gems and you would get copies of the gems for close to nothing. (but losing the tool)
It can also be used to create copies of tools made out of rare materials that can then be smelted to get the materials very easily. (Get a super rare material make a shovel then copy it a few times to be able to make a whole set with minimal work)
Additionally i looked for a way to make / find a tool that could hold items as this would let you dupe any item, however i wasnt able to find any tool that let me do this (however modpacks might have mods in the future that would let you do this).

This dupe isnt super op however it has alot of potential to be able to disrupt the pace of the modpack.

Ways to fix this could be either to change Mahou to not let you copy specific tools / enchants / gems.
Another way could be to let the tools be copyable but giving them a tag that means it cant be used to do specific things (such as smelted or put into disenchanters ect.)
