When rolling for a percentage and rolling a D10 and a percentage dice when you roll a 0 on the D10 is it a 0 or a 10. Also what would the dice look like for it to be rolled a 100, what would it look like for a 10? Oh man, the relic of a time when putting two numbers on a die side… when rolling 1d10, 0 is 10. When rolling percentile dice, its 0, unless you roll 00, then it’s 100.
