A d8, or eight-sided die, is a die that has an equal chance of rolling the integers from 1 to 8. Its most common form is a regular octahedron, in which form it appears in the standard 7-dice set used in role-playing games like Dungeons & Dragons.
Most d8s are regular octahedra. An octahedron, which resembles two square pyramids attached base-to-base, is a Platonic solid with eight sides that are all equilateral triangles.
Usually, the sum of the numbers of opposite faces of the d8 is 9.
