Once you've made a character in 'Neverwinter Nights 2,' there's no standard way in-game to change lifelong traits. However, you can use a saved game editor to make your character born of another race. Whether you'd like to be a poetic Elf or a guarded Dwarf, consider choosing a race that fits with your class; for example, Gnomes make better bards, but Deep Gnomes favor the rogue class.

I've recently finished mapping out the save game format for my own purposes with a hex editor.
Changing Character Race
The only way to change your character's race after creating him is to use a game save character editor. One example is NWN2 Character Editor, available on Neverwinter Vault. There's also NWN2 Editor from Nexus Mods. These editors use Java and allow you to modify various aspects of your character and game save file. Sorcerer's Place lists several character editors and other utilities for the game as well (see Resources).
