D8 dice roller
An eight-sided octahedral die used in tabletop role-playing games for damage, healing and other variable values.
How this die works
A D8 has eight triangular faces and returns a whole number from 1 to 8. Each face has a one-in-eight chance, equal to 12.5%. The average across many fair rolls is 4.5. It is commonly written as 1d8 in RPG rules.
When to use it
Use a D8 for role-playing game rolls that specify 1d8, including damage, healing and random tables with eight outcomes.
A fair digital roll gives each face an equal chance. This roller uses the browser's secure random number generator where available.
