D# (Glossary)

The “d” indicates “die” or “dice”, and the number following is the number of sides on the die required.  For instance, “roll a d100” means “roll one 100-sided die”.  Often, there will be a number before the “d”.  This indicates the number of these dice to roll.  For instance, “roll 2d10” means “roll 2 ten-sided dice and add the results together”.
