How is the ability modifier calculated?

It uses the D&D 5e formula, floor((score − 10) / 2). So a 16 gives +3, a 10 or 11 gives +0, and an 8 gives −1. The roller shows the modifier next to every score.

What does 4d6 drop lowest mean?

For each ability you roll four six-sided dice, discard the single lowest die, and sum the remaining three. It is the standard D&D 5e method and produces scores roughly between 3 and 18, averaging around 12.

What does the heroic method do?

The heroic method rolls 4d6, rerolls any die that shows a 1 once, then drops the lowest of the four. This shifts the average upward for a stronger, more heroic character.

Are the rolls fair and private?

Yes. Every die uses the browser's Web Crypto API with modulo bias removed, and all rolling happens locally — nothing is uploaded.

Character Stat Roller

Q: Which scores does it roll for?

It rolls one score for each of the six D&D abilities — Strength, Dexterity, Constitution, Intelligence, Wisdom and Charisma — and shows the dice, the modifier and the totals.

This stat roller generates a complete set of six ability scores for a Dungeons & Dragons 5th edition character in one click. Pick your rolling method, and it returns Strength, Dexterity, Constitution, Intelligence, Wisdom and Charisma — each with its dice, its ability modifier, and running totals — so you can drop them straight onto a character sheet.

How it works

The roller offers three methods:

4d6 drop lowest (standard 5e): roll four six-sided dice, discard the single lowest, sum the other three. Scores range from 3 to 18 and average about 12.
3d6 straight: sum three dice for a grittier classic spread with a lower average.
Heroic: roll 4d6, reroll any 1s once, then drop the lowest — biasing scores higher.

Each score’s ability modifier uses the official 5e formula floor((score − 10) ÷ 2). Every die is drawn from the browser’s Web Crypto API, with modulo bias removed so each face is equally likely.

Example

A 4d6-drop-lowest roll of 6, 5, 4, 2 drops the 2, summing 6 + 5 + 4 = 15. A score of 15 gives a modifier of floor((15 − 10) ÷ 2) = +2.

Score	Modifier
18	+4
16	+3
15	+2
10–11	+0
8	−1
