Im like four hours into the game, and I have more than enough level three magic. You can buy them in magic shops, and even find Thundara in the Vikings Cove, as well as Blizzara. You missed alot man, I suggest restarting the game, or go back through all of the dungeons, and search again.

I have a stratagy guide, so I know these things, even though I just started the game, and im only four hours into it.
