Hrm. I am a bit conflicted.. Have at the moment narrowed it down to two builds, and can't choose which one to take..
1) Stunning blast, Winter's Blast, Deep Freeze, Horror, Paralyzing Prison -> that's 9 points (including the one at lvl1), leaving at least 11 to specializations.. or
2) Stunning Blast, Golem's Fist, Dessicate, Chain Reaction, Strikes Twice, Galvanism -> that's 11 pts (including the lvl1 pre-set), with about 9 left for specializations.
And I'm not sure which one is better. On the one hand, I have 3 damage spells (winter, cone and prison), 3 dedicated stuns (winter, horror and mindblast) with other two situational (prison and cone).. But nothing really AoE. But, enough points to maximize a specialization and grab something else too.
On the other hand, I could have 3 damage spells, two of them being AoEs (fist, chain lightning and tempest), I have two stuns (mindblast and petrify), and a passive boost. But, that leaves less points for specializations.
This way, it is a choice of focusing on wide-range damage first versus focusing on targeted-control first. And I'm not sure which one is better. I guess with the specializations, it would be better to have extra control spells rather than damage spells later on - but then again,most battles have enemies coming in waves of 4-5, and getting rid of them fast would not be bad at all.. Urgh, decisions, decisions.
