While browzing the Bioware forums, I found
this discussion about gaining full experience in the Neverwinter Nights Original Campaign.
Apparently Bioware set the experience level in the OC to only 10% of what you would get in a PnP game. This was done to offset the amount of Hack-and-Slash you get in a computer game vs. PnP.
I tried the simpler method: copy the official Chapters to the /mod directory; backup the official Chapters (just in case [img]tongue.gif[/img] ) ; rename the copied chapters with the .mod suffix; open each copied chapter in the toolbox and set the experience slider to 100% (200% for the Prelude- my fighter was third level leaving the Graduation Hall [img]graemlins/hehe.gif[/img] ) .
The modules scale the encounter for your level: instead of just battling Zombies in the Begger's Nest I am fighting Zombie Warriors and Ghoul Lords.
I hope you have fun with this; I know I am [img]graemlins/biglaugh.gif[/img] .
