Represents the immutable result of a completed roll of dice. This is only ever used to represent a single type of die. Rolling a d20 and a d10 is two rolls while 2d10+3 is a single roll.

Fields

• :count - The number of times the die was rolled
• :sides - The number of sides on the die
• :modifier - A flat modifier applied to the die roll value after calculation
• :dice - A list containing the raw value for each die roll. Occasionally needed for criticals, etc
• :reduce - Indicates what function to run on the die rolls, e.g. sum (default), max, min, drop-lowest, etc
• :total - The final result of the role. In most cases, this is the value used for rule resolution
