conclusion: INT Increases base dmg output for conjurer, when adding points to Ice it also increases dmg output when using Ice spells, however not as much as INT.
This time, the experiment consisted of 3 phases. For all 3 phases, I was Physical level 18 and Conjurer level 9. I did not level either during the experiment. I fought puk hatchlings all "green" difficulty located SE of Camp Skull Valley. Each phase I only cast the blizzard spell. Nothing else was used to damage the puks. Each phase consists of 50 casts.
