KiNgBrAdLeY7: I have not progressed far, but this is easy. Also wands are nice (you find ice ones early on), but they have charges, unfortunately. They are useful though, especially against a sun-like enemy that hurls firebolts at you!
Wands are only really useful early on because the game doesn't give you enough of a supply later on.
Potions can be quite useful, especially the Ghost Form ones (I believe you need 8 skill to make these). Cast Ghost Form and enemies won't be able to hit you with physical attacks, but you can still use spells. Combine it with the Reflect Projectiles spell (late-game spell that requires 14 in a skill you don't even get until the end) and even the endgame is quite manageable on Hard++ difficulty.
By the way, if you want to go for Reflect Projectiles, I recommend saving the orb that lets you respec until you reach the point where you can buy the spell and are at least level 14. Of note, this doesn't come up until after the last real boss fight.
