Question 1

What is a d100?

Accepted Answer

A d100 is a hundred-sided die (percentile) with 100 faces, used in tabletop RPGs like D&D 5e and Pathfinder. The d100 (or percentile dice) is rolled using two d10s — one for tens and one for units. It's used whenever the DM needs a percentage chance or consults a random table. Wild Magic Sorcerers live and die by the d100 roll on the Wild Magic Surge table!
