Preguntas frecuentes
Are the rolls fair?
Yes. Each roll uses the browser's cryptographic random generator with rejection sampling, so every face is exactly equally likely.
What does 3d6+2 mean?
Roll three six-sided dice, add them up, then add 2.
How do I roll with advantage?
Roll 2d20 and take the higher die shown in the result.
