How to use it
Attack rolls and checks
Set the modifier to your attack bonus or skill bonus and press d20. Natural 20s and natural 1s are flagged so you don't miss a crit.
Advantage and disadvantage
Roll two d20s and keep the higher (advantage) or lower (disadvantage). The die you didn't keep is shown crossed out.
Damage
Set Number of dice and press the die, or type it: 2d6+3 for a greatsword, 8d6 for fireball. Critical hits double the dice, not the modifier, so 2d6+3 becomes 4d6+3.
Ability scores
Type 4d6kh3 to roll four dice and keep the highest three, six times. Or use the stat roller, which does all six at once.

Questions
Is this dice roller fair?
Yes. Each die is rolled with your browser's random number generator, so every face has the same chance. Nothing is stored or sent anywhere.
What does 2d6+3 mean?
Roll two six-sided dice, add them together, then add 3. The first number is how many dice, the number after d is how many sides, and the end is the modifier.
How does advantage work in 5e?
When you have advantage you roll two d20s and use the higher result; with disadvantage you use the lower one. If you have both, they cancel out and you roll one d20.
What does 4d6kh3 mean?
Roll four six-sided dice and keep the highest three. It's the standard way to roll ability scores (4d6, drop the lowest).
Is it free?
Yes, free and unlimited with no sign-up.
