Representation of dice for parameters scaled with current level depth.

Frequency distribution for casting dice scaled with level depth

data Dice

Dice for parameters scaled with current level depth. To the result of rolling the first set of dice we add the second, scaled in proportion to current depth divided by maximal dungeon depth. The result if then multiplied by the scale --- to be used to ensure that dice results are multiples of, e.g., 10. The scale is set with |*|.

Mean value of dice. The scaled part taken assuming average level. Assumes the frequencies are not null.

reduceDice :: Dice -> Maybe Int

Dice for rolling a pair of integer parameters representing coordinates.

data DiceXY

Dice for rolling a pair of integer parameters pertaining to, respectively, the X and Y cartesian 2D coordinates.
