## Why does a d10 have a 0?

It’s a 10. The die is a d10, and when such a die is rolled, the 0 is usually read as a 10. Some RPGs use it as a 0-9, but that’s more of the exception rather than the rule. The only time a 0 on a d10 is read as a 0 is when it’s rolled as a pair of d10s to get a d100, or percentile dice, where a “00” is 100.
