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.
Rank 4: Spells
Heal
Healing differs depending on the class you choose. Warriors have less effect from casting a heal, whereas Rogues do a little bit better job. The best class to heal is a Wizard.
Mana used for healing depends on how much health you lost. The higher rank Heal you have, the less mana per 1:1 , again Wizards can get the highest rank because of its max amount of Wisdom.
This spell will heal you and restore lost health. The higher level the more health. Sorcerers have a significantly greater effect than healing potions. And the higher spell level you have the less mana it uses.

Fireball
Fireball is one of the first spells you can shoot at your enemy, but it is less effective. The enemy has to be on a straight line; if the enemy moves, you will miss your shot, and that’s mana lost.
Will throw a Firebolt towards your enemy at a low cost to mana. No splash damage.

Charged Bolt
With a lot of enemies around you, you can shoot a few charges off, and you will properly kill most of them, but it is a bit random if you hit or miss. But if they are close to you, they will most likely hit your enemy.
Many small lightning bolts will crawl toward your enemy, it will run in the direction you are shooting it.
