Dice and Rolls

Most actions in D&D use a 20-sided die (d20).

The Basic d20 Roll

1. Roll 1d20.
2. Add the ability modifier the GM names (from your six abilities).
3. If you are proficient, add your proficiency bonus once.
4. Meet or beat the target number to succeed.

Example: To sneak past a guard, roll 1d20, add your Dexterity modifier, and if you're proficient in Stealth, add your proficiency bonus too.

Advantage and Disadvantage

• Advantage: roll 2d20, take the higher result.
• Disadvantage: roll 2d20, take the lower result.

If you have both at once, they cancel out and you roll normally.

Three Common Roll Types

• Ability check: Try a task, compare to a Difficulty Class (DC) set by the GM.
• Saving throw: Avoid harm, like dodging a fireball or resisting poison.
• Attack roll: Try to hit a creature's Armor Class (AC).

Passive Scores

Your passive score is 10 + your modifiers. The GM uses it for things you're always doing, like staying alert.
