Need more support for the mage!!

you can use wizard hats (and the green fremennik hat which gives +3 bonus), not sure about wizard robes, maybe you can kill dark wizards for black robe, there's seers helm and mystic items too i think, ahrims is pretty hard to obtain, never seen infinity in this game. You can use staves and amulet of magic for bonuses.

no need to alter bronze armor lol
