The above works brill for a sorc, to put 20 into a few skills cant always go brill, but if u go heavy in one tree, like ice, ensure u have very high masteries for that tree too. Warmth is a must, Mana shield. Maybe static field if you want the extra defense. Chliing armour is probably the best at around lvl 5. utility skills like telekinesis and teleport are only worth one point each, nothing more.
