You can use the same console cheats that were used in the original NeverWinter Nights
First, you will need to hit the tilde (~) key and type in "DebugMode 1" (case sensitive). Then hit the ~ key again and press TAB. This should show you a list of the different functions available. Hit TAB again to scroll down the list.
Cheats: (case sensitive)(X is a number)
SetCHA X - Sets your Charisma
SetSTR X - Sets your Strength
SetINT X - Sets your Intelligence
SetWIS X - Sets your Wisdom
SetCON X - Sets your Constitution
dm_givegold X - Gives the X amount of gold to you
GetLevel X - Raises you an additional X amount of levels
dm_god - Makes you invulneralble (does not require you to click on the player character)
On some of the cheats, it will simply give you a message saying "success" after you enter the code and press ENTER. Other ones, such as the SetCHA will say "Entered Target Mode". You must click on your character to enable the changes on your character.
