This is a good guide too, but i prefer to use special abilities during fight instead of physical attacks only.
Now I've decied to unlearn all the abilities because I realized that i never use Battle Rage, so i gained 2 points and gave them to Thousand Strike and Whirlwind, taking them to level 7
Now I'm level 32 with 3/4 parts of Ulthring Set (i'm about to get the Helmet) and a melee damage around 280-300...a single shot of Thousand Strikes is letal for everyone

I think i'll bring all my abilities arond level 10...
It's a shame the fact that when you get all the Sets and all the abilities to high level, the game ends -.-"
