Makatak: There are alot of races/classes/skills/feats to choose from so I just clicked the 'recommended' button for everything to play as a Chaotic good human fighter with standard kit. I do the same thing whenever I level up. I'm using the maps at gamebanshee.com as a guide so I don't miss side quests. And I've hit a roadblock at the prison. The spellcasting prisoner I had to attempt over and over until I got lucky and interrupted his casting 2 or 3 times in a row with myself and my henchmen Sharwyn. Then I got to the Orc and had the same problem. Is this a bad build? Or am I missing something?
This is NWN diamond I'm talking about.
Never ever use the recommend button. You'll always get the worst decisions from it. BW was trying to push the RP aspect of the game, hiding all the really good choices.
The best fighter in a low magic scenario is a str based cleric because it's basically a walking magic item shop. Buffs and heals are the real power of this build. But the Harm spell is devastating even in high magic settings and Heals are always welcome.
Human
str 16
dex 10
con 10
wis 15
int 14 (plenty of skill points, get Tumble, Concentration, Spellcraft, and something else)
cha 10
As far as ability increases, first get your wis to 19 so you can cast 9th level spells, then the rest goes to str. For feats, you want martial weapon proficiency, combat casting, KD, imp kd, the rest would be metamagic feats, Extend most importantly, and Empower.
There are a number of good domains to choose but you can only have 2:
Earth
Plant
Magic
Strength
Travel
War
For weapons, use the best you can find. Shields add a lot to your defense especially when you consider magic.
