Good chance to add this
Was playing again and of course I have find something new called more skill books so I have taken fireball
So here is my conclusion
After 6 playtroughts with ultimate mage I have find out that my build is powerful to finish game
I have also understand that at the end I always end up with many unused skill ponts
If you have them
put them to fireball
It won"t hurt to have more firepower
NOTE:Use fireball after battletower
early is uselees and you need your points for better skills
