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.

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

D&D character stat roller

Roll a full set of six ability scores at once. Choose 4d6 drop lowest (the standard 5e method), 3d6 straight for a grittier classic feel, or a heroic variant that rerolls 1s for a stronger spread.

Each score shows its dice and its ability modifier, calculated with the official formula floor((score − 10) / 2), along with the total and modifier sum. Dice are rolled with the browser’s Web Crypto API for fairness, and everything runs in your browser — nothing is uploaded.
