For a brief period of time (or maybe a toggle?), conjured weapons will allow any stamina based weapon you are carrying and its associated skills to scale off magicka. To balance things a little, any physical damage in these skills will be converted to magical.
This could open up a world of customization options for magicka builds (True magical archer anyone?). More importantly, a pure magicka build will no longer complain about carrying a two handed sword.
What do you guys think? Too OP?
