There are 7 different dice in Descent: Journeys in the Dark (Second Edition) grouped into three types.
- The Blue die is called the Attack Die, and is used for almost every attack. Please note that not every damage-dealing ability is an attack.
- The Yellow, Red, and Green dice are called the Power Dice, and are usually used in conjunction with the Blue die to roll "an attack." Only the Yellow and Red power dice were included in the Base Game; the Green power dice were added in later expansions.
- The Brown, Gray, and Black dice are called the Defense Dice, and are usually used to defend against an attack, while the Gray and Black dice are used together for , , , and tests.
The table above assumes the attack is not a miss (excludes this as a possible result). The probabilities including the possibility of a miss is 0.83 multiplied by the values listed.
The Lucky column assumes a hero will use Lucky Charm to reroll in case of failure. The Fortune column assumes an Overlord will use Dark Fortune or a hero will use Fortuna's Dice to reroll one of the dice in case of initial failure. The Wicked column assumes an Overlord will use Wicked Laughter if a hero initially passes their attribute test. The Wicked column also applies to Befuddle, except that for the Attribute 0 row, the probability of success is exactly 0.
