How the D20 Advantage / Disadvantage Roller works

Advantage and disadvantage are core D&D 5e mechanics: instead of modifying a roll with a bonus or penalty, you roll two d20s and take either the higher (advantage, representing a situational edge) or the lower (disadvantage, representing a hindrance). Both dice are always shown, with the unused roll struck through, so you can verify exactly which value was taken.

How to use it

1
Choose roll typeNormal for a single d20, Advantage to roll twice and take the higher, Disadvantage to roll twice and take the lower.
2
GenerateXrandom rolls one or two d20s as needed and clearly shows which value was actually used.

Frequently asked questions

Do advantage and disadvantage cancel out if I have both?

Per standard 5e rules, yes — if a roll would have both advantage and disadvantage from different sources, they cancel out and you roll normally with a single d20.

Why show both dice instead of just the result?

Transparency — you can verify the higher or lower value was correctly selected, the same way you'd see both physical dice on a table.

Is this the same as rolling 2d20 and adding them?

No — advantage/disadvantage always uses just one of the two values (the higher or lower), never their sum.
