Dice

Starfinder requires a set of polyhedral dice. Each die has a different number of sides—four, six, eight, or more. When these dice are mentioned in the text, they're indicated by a “d” followed by the number of sides on the die. Starfinder uses 4-sided dice (or d4), 6-sided dice (d6), 8-sided dice (d8), 10-sided dice (d10), 12-sided dice (d12), and 20-sided dice (d20). If you need to roll multiple dice, a number before the “d” tells you how many. For example, “4d6” means you should roll four dice, all 6-sided. If a rule asks for d%, you generate a number from 1 to 100 by rolling two 10-sided dice, treating one as the tens place and the other as the ones place.
