To access cheats in Neverwinter Nights, press the “~” key (no need to hold down Shift) and you’ll see a “›” appear in the top-left corner of the screen, followed by a blinking cursor. Enter “DebugMode 1” (without the quotes) and you’ll see the word “Success.” To enter codes, simply press the “~” key and type a code. When you see “‹number›” after a code, replace it with a numerical value (if you see a space between the code and “‹number›,” make sure you include it).
All the codes, including the command “DebugMode 1,” are case sensitive, so remember that.
