 "Hard Dice" are considered to always have a value of 10, while "Wiggle Dice" have a value assigned by the player "after" the rest of the pool is rolled.The shorthand notation for Hard Dice is "hd" and Wiggle Dice is "wd", so a Dice pool of six regular dice, two Hard Dice and one Wiggle Die would be noted 6d+2hd+1wd.Nemesis introduces "Expert Dice", which may be used as normal dice, or the player can select their value "before" the roll, but no two Expert Dice can be selected to have the same value.
