FAQ
What is a d8 used for?
The d8 is a common damage die in D&D (the longsword and many spells) and the hit die for several classes. It gives an even chance of any value from 1 to 8.
Are these d8 rolls really random?
Yes. Each die uses your browser’s cryptographic random generator with rejection sampling, so every face has an exactly equal chance — no modulo bias, no loaded dice.
Does this dice roller run in my browser?
Yes. Every roll happens locally on your device — nothing is uploaded and it works offline once the page has loaded.
