# Die Results / D Effects

#### General Rules

1. Some cards may list a "D" calculation as part of the effect. The D refers to die or dice where a number following the D refers to the sides present on the die. E.g., a D6 is a six-sided die.
2. Effects that specify a die-based calculation or result will have the player roll the appropriate die during resolution of the effect.
3. Only the use of fair dice is approved for these results — See [Randomization](/game-mechanics/game-mechanics-miscellaneous-topics/randomization.md)
