Neverwinter Nights Easter Egg - Cheats for Neverwinter Nights

Before you use the cheats you may need to go to the file nwn.ini in the game folder and add the line: "Debug Mode=1" (without the quotes) to the section under "Game Options". This can be done with Notepad or a similar text editor.
Now while playing press ~ and type DebugMode 1 (case sensitive), and press enter.
Now press ~ again and type:
(# always being a number of your choice)
Getlevel # = Get Level #
dm_givegold # = Get # GP
SetCON # = Set Constitution to #
SetWIS # = Set Wisdom to #
SetINT # = Set Intelligence to #
SetSTR # = Set Strenght to #
SetCHA # = Set Charisma to #
dm_levelup = Level up Character
dm_god = Invincibility
dm_heal = Heal Hit Points
dm_givelevel # = Get Character level #
dm_mylittlepony = Get a hobby horse (cool!!!)
dm_cowsfromhell = Flying cows that kill
GiveXP # = Get # Experience Points
GetLevel # = Go up # Levels
ModSaveFort # = Set Characters Reflex
ModSaveWill # = Set Characters Will
ModSpellResistance # = Sat Chars. Spell Resistance
SetAge # = Make Age #
SetAttackBase # = Set base attack #
SetAppearance <race> = Make race (human, elf etc.)

Press Enter after every cheat and to type in the next cheat press ~ again. All cheats are Case Sensitive.
When you use these cheats, and you try to change chapters (e.g. from the Prelude out the stables into Chapter 1) the game tells you that your character is invalid and the login is refused. to avoid this problem, find your nwnplayer.ine file in the base NWN directory. Then find the line saying "Single Player Enforce Legal Characters=1".
Change that 1 to a 0, and your troubles are over.

(NOTE): If you actually like to play fair in games and you like the challenge of the game, don't use these cheats because it gets way too easy...
