ok, easiest way this is explained is in a power leveling thread on Gamefaqs...
http://boards.gamefa...27088945&page=1kinda hard to grasp at first, but in short...
when you level up, your multiplier for that stat, will be the number of times you leveled a skill divided by 2, with a max of +5.

you say?
ok... basically you want to get that plus 5, or as close as possible... so what you do, is level up a specific skill or several that have the same STAT (ie strength, etc) from your MINOR skills, 10 times, giving you a +5 when you do level up (minors dont go towards leveling up) then after you get the 10 levels in your minor, go for 10 skill levels of a similar STAT in your major, once you level up, pick the two +5 stats, and luck.
try to do as best you can to follow that if you want a beast character, im already level 16 and just found this out... and have been getting +2 multipliers which are crap... but im still having fun.. maybe if i start a new character i might do this "power leveling" but not now.
hope that helps
