Can you raise it to 100 by casting that spell 100 times? Also, I'm not familiar with the skill settings yet. Does it matter *which* conjuration spell is cast? Does it simply require X number of conjuration spell casts per skill level, regardless of which spell it is?
Didn't try to get 100, but im at 47 on conjuration, and yes every single time I cast Raise zombie (sorry it's the only conjuration spell that I have) I raise the skill by 1.
But as I said, with another character, Conjuration will work just fine, I will need to cast a very good amount of Raise Zombie's spell in order to increase the skill.
