built a little thing last year, im sure there are a billion spins on character builder mods, so heres mine: Click Here
there are areas to test low level to high level characters, iddilicus's level up room modified, pretty much everything you can get in game and some custom noodling stuff, an alignment changer and an xp dropping pixie.
It's a nice quiet litle mod to build your character up a level at a time, gives ya time to think and time to redo stuff in the nwn setting.
