Question 1

What is a d10?

Accepted Answer

A d10 is a ten-sided die (pentagonal trapezohedron) with 10 faces, used in tabletop RPGs like D&D 5e and Pathfinder. The d10 is unique among standard RPG dice — it can be numbered 0–9 or 1–10 depending on the set. It's essential for heavy weapons, powerful cantrips like Eldritch Blast, and when paired with a percentile die, forms the d100.
