The dice number refers to the number of dice to roll within an entry. Dice entries are provided in the format XdY, where X is the dice number and Y is the number of sides of the dice (corresponding to the dice level).
The dice number cannot normally be reduced to less than 1. An effect that overrides this rule and reduces the dice number to less than 1 eliminates the entry entirely. Negative dice numbers are not allowed. If an opposed roll entry is removed as a result of dice number reductions, it automatically fails rather than automatically taking effect.
If at any time a loop, recursion, or similar endlessly-repeatable play is made that affects dice number, it can only modify the dice number to a maximum of +/- 3 regardless of the text on the cards or entries.
