# D4

A four-sided die shaped like a tiny pyramid, usually read from whichever number sits at the top point rather than a flat face.

## Detailed definition

The D4 is the odd one out in a [polyhedral dice set](/glossary/polyhedral-dice-set/) — instead of landing on a flat face like every other die, it’s a tetrahedron that lands point-up, and you read the number printed around the base of whichever corner is pointing at the ceiling. It’s also the die most likely to end up wedged in a bare foot, so most tables learn to respect it fast.

You’ll see D4s called for in small amounts — a single die for a dagger’s damage, a couple for a spell effect — rather than rolled by the handful. If a listing mentions a D4 at all, it’s usually a lighter RPG-adjacent title or something using [dice notation](/glossary/dice-notation/) like “1d4” for a minor outcome.
