A dice roll (U.K.) or die roll (U.S.) is a roll of one or more dice to provide the random element of a game. This is used extensively in pencil-and-paper games, while in Neverwinter Nights, these rolls are simulated with the pseudo-random generation of a number. Example: If a saving throw is being rolled at +7 against a DC of 5, rolling a natural one results in a failed save (unless saving throw auto-failure is disabled) even though 1 + 7 is more than the DC.
