Yes. And because I don't pretend to believe that I am in any way equal to a god.
It is a rather advanced spell. Not the most difficult, but certainly up there. I often keep in close contact with at least one mage capable of casting it, largely because it can duplicate nearly any other spell, which is what makes it particularly useful in this case. There is a malleability to the spells duplicated in this manner. Restrictions can be nudged just a bit. And it has limitations, as well. But if you wanted to cast this item into a tiny little demiplane that no one would ever find, it would be able to do that.
It is a bit ironic, though, that I have only ever needed to have it cast for genies.
