Ability score roller
Roll a full set of six ability scores in one click. Pick the rolling method your table uses; the roller shows every die, crosses out the one that is dropped, and gives each score's modifier and the total of the array.

How to use
- Choose the method: 4d6 drop lowest, 3d6 or 2d6 + 6.
- Six scores are rolled at once. Each row shows the score, its modifier and the dice, with the dropped die crossed out.
- Tick Sort from highest to lowest to assign the best scores first.
- Press Roll again for a new set, or copy the scores with their modifiers.
How it works
- 4d6 drop lowest: four dice, the lowest one is removed (if two dice tie for lowest, only one of them is dropped), the other three are added. Range 3–18.
- 3d6: three dice added. Range 3–18.
- 2d6 + 6: two dice plus 6. Range 8–18.
- Modifier = ⌊(score − 10) ÷ 2⌋.
Under the table you see the total of the six scores and the sum of their modifiers, two quick ways to judge an array.
Example
A 4d6 roll of 5, 2, 6, 4 drops the 2: 5 + 6 + 4 = 15, modifier (15 − 10) ÷ 2 = 2.5 → +2. If the six scores come out as 15, 14, 13, 12, 10 and 8, the total is 72 and the sum of modifiers is +5 — exactly the standard array.
Tips
- Agree on the method and any reroll rule (for example, reroll if the total is below 70) before anyone rolls.
- Roll in front of the group: share the screen or copy the result into your chat.
- If your table prefers buying scores instead of rolling, use the point buy calculator.
Frequently asked questions
How does 4d6 drop lowest work?
Roll four six-sided dice, ignore the lowest one and add the other three. A roll of 3, 1, 4 and 6 drops the 1 and gives 3 + 4 + 6 = 13. Repeat six times for the six abilities. It is the most common way to roll stats because it gives slightly better characters than 3d6.
How is the modifier calculated?
Modifier = (score − 10) ÷ 2, rounded down. A 10 or 11 gives +0, 12–13 gives +1, 14–15 gives +2, 16–17 gives +3 and 18 gives +4; an 8 or 9 gives −1.
What do 3d6 and 2d6 + 6 mean?
3d6 is the classic straight roll: three dice added, so scores run from 3 to 18 and average 10.5. 2d6 + 6 adds two dice to 6, so no score is below 8 and the average is 13; some groups use it to avoid very weak characters.
How does a rolled array compare with the standard array?
The standard array 15, 14, 13, 12, 10, 8 adds up to 72 with modifiers totalling +5. Compare your total and sum of modifiers with those numbers to see whether your roll is above or below that baseline.
Are the dice fair?
Each die is drawn with the browser's crypto.getRandomValues without modulo bias, so every face from 1 to 6 is equally likely. Rolls are made on your device and not stored anywhere.
