I have just started playing again and have been mulling around a build that would eliminate many of the synergy needs while allowing a sorc to build into at minimum a maxed skill in each tree. I do this for solo games so I can't get tripped up by a dual Immune mob. I also like it for farming Countess as she is F/C Immune and the Dark archers that can spawn nearby are always Lightning Immune. After Consideration and some drawing/planning I have worked up a build that uses Fireball, Nova, Frozen Orb, and Enchant. I decided to add Enchant to this build for the +AR for the potential of using a "Might" merc from A2. (Enchant wouldn't need to be maxed, but just boosted somewhat if the testing on it pans out.) This build uses 10 other points to open all of these skills and also allow level 1 Teleport. That leaves 20-30 (Depending on how high you take Enchant) points to be pumped into whichever masteries/synergies you desire to use for your "Main" spell. I normally use Orb as the Cold mastery will lower resist of mobs and leave just the Cold Immune's to cluster around my hireling to be either nova'd or fire-balled down as a group. I like this build also due to the fact that I can teleport and drop a few nova's if I begin to be swarmed to knock most of the group into hit recovery to allow me time to get a teleport escape vector. Would love to hear thoughts and comments on this as I haven't played much in years and I am trying to plan my own builds and not just go get a "Stock" build from somewhere just because its easier.
