Spells
 

I think there should be a skill for all sorcerers they start out with... its the skill Concentration.
The higher your magic level or wisdom level is, the less you fail to cast spells , for instance when someone hits you and interupts your spell.
You were hit and lost your spell! The rate of that should be lowered if you concentration, MAGIC level or WISDOM level is higher.

I sudgested this a few times before so I support this as well...

*support* It makes sense, and also, on top of that, as you level up magic/wisdom, your spells/prayers should do more damage, not double damage off the bat.
