A player created this homebrew copy spell:
Components: V, S, M (an amount of coins equal in worth to the (unenchanted version of) the copied item)
Casting Time: 1 minute
When cast, the spell analyzes every part of a non-living item that fits in a cube of 5ft. squared and creates a near-perfect replica. The differences are not substantial enough to hinder the item's original function, but are substantial enough to distinguish it from the original (DC 10 perception). Any enchantments the item has are not carried over to the copy. The coins are immediately consumed at the start of the spell, but can be retrieved were the spell to be halted prematurely, in which case the unfinished copy disappears.
I am pretty sure it is not a good idea to allow it as it stands right now and am thinking about restricting it more.
I doubt that I am thinking about every possible repercussion.
With that said - I'd like some input about its viability, how to restrict it more or if it's hopelessly gamebreaking.
