Spells
Spells can be used by all classes except the barbarian if you have that “cheat” on. For some spells, you can only get to a certain level because of your class. If you are playing as a Sorcer you can get higher-level books.
You can buy books or you can find them in the dungeons. A good tip here would be if you find an item that has high + Magic as a prefix, save it in town for when you find that book you need to get to the next level. But you don’t necessarily want to run around with that weapon, it is a stat stick waiting in town. If you find a book but you cant read it yet, I recommend you save it in town or inventory until you get an item that can give you more + Magic, or if you just need to gain a level or two.
I will try to make information for each level, so you can see how much you gain from each level. plus how much Magic is required.
Prices below are for the books, at Adrian, some you can buy, and others you have to find. But the sell price is not always good.
