roll about 10 6d dice instead of 3 when you make your rolls

strength and constitution...then maybe dexterity
concentrate on a weapon path, and stick to it....you may want to specialize in both a long and short range weapon...or just one with a shield....
i'm sure the rules changed a ton as i haven't played the original game since 1985 probably....neverwinter nights rocks though....haven't played that in over a year....might have to reinstall...was a magicuser/thief....
personally i always like magic users more....much harder to play at beginning levels, but way more potent at higher levels....
i used to play diablo, and i built a spell caster all the way up and just owned the last few levels....
there was a secret level called 'the mad cow' level....where 1000's of minotuar looking monsters came at you....i wasted them all....my buddy with the fighter didn't last 15 seconds....the monk, slightly longer...
