Another of these spells that at first look pointless. However, it is actually useful.
Using it on a simple object (meaning nothing plot relevant) will create a perfect copy of said object. So in a way it is the object equivalent to "Clone". This is downright useful for example to create powder kegs from one single keg in the mage's possession, or create multiple Torches. However, the spell can't copy anything magical or too valuable, not can it copy money (it is no False Coin spell after all).
