To start off put 10 points into Charisma. and continue putting points to it until you reach 26 on level 5 on the next level put 3 on Magicka and 1 charisma then from here to level 20 just put all points into Magicka Important things you should do :

1. In the earlier levels just taunt on your enemies
2. Use magic spells when you get access to them
3. DON'T buy unnecessary spells like : teleport;gale;command.... you will just waste money it's better to buy damaging spells such as : Fireball ; Lightning bolt ; Hell Fireball ; Frightening Bolt etc ....
4. Buy armor before facing Marksman Dantus because he has a bow and also on Wizard Sagan because he has Deadly spells if you have seen my run i barely survived his spells even with great armour especially on the PC (downloadable) version because spells are buffed in that version
5. Play on the PC version NOT on the WEB version since the spells don't do alot of damage in this version compared to The PC one (version) and that's basically it if you have any questions Feel free to send me a message
