Dice notation
1d20+5: roll one 20-sided die and add 5.2d6+1d4: add different dice together, for example a weapon plus a bonus.2d20kh1: roll two d20s and keep the highest one (advantage).2d20kl1: keep the lowest (disadvantage).4d6dl1: roll four d6s and drop the lowest.
Dropped dice are shown faded, so everyone at the table can see what happened.
Rolling ability scores
The classic method is to roll 4d6, drop the lowest die and add the other three, six times. Assign the six totals to Strength, Dexterity, Constitution, Intelligence, Wisdom and Charisma. The roller also shows each score's modifier: (score − 10) ÷ 2, rounded down, so 15 gives +2 and 8 gives −1. Check with your Dungeon Master whether your table uses rolled stats, the standard array or point buy.
Natural 20s
A single d20 that lands on 20 gets a celebration, and a natural 1 is marked too. Critical hits usually mean rolling the damage dice twice, for example 4d6+3 instead of 2d6+3.
Frequently asked questions
Are the rolls fair?
Yes. Each roll uses your browser's cryptographically secure random number generator, so every face is equally likely and rolls can't be predicted.
How do I roll with advantage?
Click Advantage, or type 2d20kh1. Two d20s are rolled and the higher one counts.
Can I add my modifier?
Yes. Type it in the notation, such as 1d20+7 or 2d20kh1+4.
Does it work for Pathfinder and other games?
Yes. Any game that uses standard polyhedral dice works the same way.
