You get 4 stat points each level. I've been using a warrior with mage and ranger abilities, so for each level I'd put 2pts in strength, 1 in dex, and 1 in intel. Once I got to about 25 and wanted more intelligence, I switched it to 2 intel, 1 str and 1 dex. Because of that, as of right now (at lvl 27) My melee resistance is over 30 while ranged and magic resistance are both at 28. Conditioned, heightened, and indom are all well over 50. Just keep it even and consistent and you'll have an all-around good guy.
