1) Exp Caps - there are none. Need to cap exp off on a yellow so you don't get insta-dings. 1 level 8 shouldn't give 20 times the amount of exp as an even con level 5 mob does.
2) Mana Pool - Don't know what's up, but the Base mana pool is really small :(
(I am working on Leveling a SK now, he's level 9, wrote spells down that I need to scribe
