Misc item user is actually pretty harsh, even OP, when using artifacts, or at least it used to be. Not as super as when histfig migrants first became a thing, and came dressed like Mr. T, but still pretty strong.
Adding magic effects could be quite entertaining. That brings up an interesting question though..
Since magic is going to be based on spheres of influence, it can possibly make deities a more active force in the world besides just random curses for vandalism and profanination. Are there any plans for special moods for priest caste dwarves in fortress mode? It would be an obvious mechanic to get sphere aligned artifacts, where type of artifact would not be tied to the dwarf's skill base, but wholly on the alignment axis system, so that eg, a god of music worshiper would produce divinely empowered instruments, if they are completely devoted to worship. Currently, a dwarf selects an object class based on skill set, which determines which kind of workshop they claim. A new kind of mood, say "holy work", for dwarves with severe skill rust, and high experience in temple disciplines (suggesting dedicated priest position) could produce magical artifacts, without training a craft skill to legendary, (similar to " fey" mood), and allow proper object alignment and type based on deity. This could be made a little more interesting by weighing dwarf character traits, and some other features (like current emotional state) to influence and refine object type creation from the short list if sphere aligned objects and possible magical effects. The need for extensive skill rust, and high temple activity would make this a very rare mood type, which limits abuse. Do you have any plans for such a thing, and if not, what do you have in mind there?
