I don't know how to build, since I am still new. I just tossed all my points into maelstorm and lightning ball with the icy wind skill. I've seen some builds that say it's pointless to go into all the synergies, but then again, makes no sense to me, being a D2 player, Synergies = GG.. :/ Game kind of confusing, if it's worth or not to max.
