This is odd, as I am having the same problem with my SK, but its slowling raising its skill level. I go to PoK and grab a C3, then summon my lowest level pet, then nuke his *** with 'Ward Undead' until mana drains. You should improve a decent ammount of times. When mana runs out, med. Mod rods help very well for raising skills, also. Just curious, whats your Int at? Mines 84, and as a 44 SK, I feel like I lack in the casting department.
