Hi everyone, I recommend you add a lot of points to strength, like every point.
Skills I recommend max "holy light," "increase all attributes", "blade storm (requires hurricane 1 and 2)," then possibly "berserk" or "speed up" and you may use the remaining points on "big bang (requires energy wave and magic wave)" for another big damage item, or use the points on proficiency of ____ (I recommend you use the sword for it's medium speed and medium damage) and in the end you want your armor to be enchanted with "magic resistance, block rate, attack bonus, critical hit" and have your weapon with poison or shock (I prefer shock personally, because poison tends to do a low amount of damage for a short time on higher level monsters then you); I choose this set up because the final boss (two-headed ogre) requires large amount of damage, tip kill the end with "blade storm" and use "berserk, attack, defense potions" (bring 5 of each about), dodge his attacks until he stuns himself otherwise you'll take damage and do nearly no damage to him, when he's lower then half hp, he'll summon ghost and you want to use "blade storm with those 3 potions to kill them in one shot, or it's extremely annoying is much more difficult and his speed, attack damage or moves powers will "triple" so watch out.
PS. I feel like a nerd :P
