Having wrecked Skyrim on legendary by min/maxing warriors and archers using crafting skills, I am having a hard time playing a mage on adept.

I would appreciate all advice to push my gameplay as far as possible. I'm doing stuff like stocking up on shalidor's insight scrolls, stocking up on fire/frost/void salts, charcoal and rolls of paper to craft atronach scrolls at the forge, and save magicka in fights that way etc. I haven't got the secret of arcana yet but I'm aiming for it. I'm also gonna try to get lots of elsweyr fondues but moon sugar is hard to find.

Basically, I'll need any misc. tip/trick/boost to magic I can get. Even if it's advice for collecting moon sugar or easily leveling certain skills.

Replies are much appreciated.
