Think i found a glitch though (PS3)
So, the spell Muffle seems to just keep giving huge XP gains to Illusion, it has suffered some diminishing returns; initially it leveled me up with each use now it takes two or three, but i am easily able to get it from lvl 15 to lvl 30 in probably 10 - 20 minutes
I haven't experimented with other Apprentice level spells sorry, are they all supposed to give huge gains? it's probably intentional but i really feel it's XP gain should be halved if not more
anyway i rolled back my save since i don't like cheating\boosting but thought it worth mentioning
