I recently made a character with the Atronach sign and obviously I picked alchemy as a major skill too. I want to MAKE restore magicka potions instead of buy them because they are so expensive and I want to level up. So, does anyone know where I can get a lot of restore magicka ingredients fairly easily?

I'll be a bit coy here to avoid spoiling things for anyone who likes to discover alchemical magic on their own. . .

Here are links to two ingredients that combine at the novice level to make restore magicka potions. Both ingredients are commonly available and the links show where they grow in concentrations:

Happy potion making!
