I'm currently leveling a warlock and I just hit level 20. I'm looking for some kind of build that will allow me to solo effectively, and if at all possible be able to pull my weight if I get a chance to run some dungeons along the way. So far, I put 10 points in the Magi Shield line in the Warlock achievement tree then I started down the Strength line to get the spell crit increase. Am I following the right path? I'm just trying to get an up-to-date build that can tell me where I should be investing points, and at what priority.
