Is there a breakdown of what each skill point should go into at each level up for an optimal setup?
We normally have 26 points to put till end of the game (considering that you will most likely finish the game lvl 19, with "liked" as your fame lvl). It usually goes 1 Prismatic Bolt and 2 Charge mastery after the skill reset (assuming you got lvl 3 after turning the first quest, which is pretty likely), then putting Charge Mastery to lvl 5 will help with the early game, since we didn't buy potions yet. After you reach lvl 7, grab Shocking Burst (SB) and Elemental Attunement. Then we only put points while we wait for Eldrain's animation to end. Just put all in SB, and 1 more point in Elemental Attunement. When you get lvl 14, grab Frost Phase and all the Brands you can. From now on, just keep upgrading SB and the Brands whenever you can (focusing on SB).
