How to use the D&D Ability Score Roller
Generate six ability scores at once.
Each score shows its modifier, e.g. 16 = +3.
Place scores into STR, DEX, CON, INT, WIS, CHA to suit your class.
Many tables allow a re-roll if the total is very low.
How 4d6-drop-lowest shapes a character
Rolling four dice and dropping the lowest is a deliberate design choice: it nudges scores upward (the average result is about 12.2, versus 10.5 for a straight 3d6) and makes a really low stat rare, so most heroes feel capable. The spread still allows the occasional brilliant 17–18 or an awkward 6, which is exactly what gives a randomly-rolled character personality. Compared with the fixed standard array (15, 14, 13, 12, 10, 8) or point-buy, rolling trades balance for excitement — your wizard might luck into a 17 Intelligence, or you might have to build around a clumsy 8 Dexterity.
Reading modifiers and building a character
The number that actually matters at the table is the modifier, calculated as floor((score − 10) / 2). A 16 gives +3, which you add to attack rolls, saving throws or skill checks tied to that ability. When you assign your six rolled scores, put the highest into your class's key ability — Strength for a Fighter, Dexterity for a Rogue, Intelligence for a Wizard — and your second-highest into Constitution for extra hit points. If your group prefers a guaranteed-balanced party, agree on the standard array instead; if you love the drama of fate, roll here and let the dice decide. Want plain dice too?

Frequently asked questions
What is 4d6 drop lowest?
You roll four six-sided dice, discard the single lowest die, and total the other three. Doing this six times gives a character's ability scores. It produces scores roughly between 3 and 18, averaging about 12.2.
What does the modifier mean?
In 5th edition D&D the modifier is floor((score − 10) / 2). A 16 gives +3, a 10–11 gives +0, an 8 gives −1. The modifier is what you add to the relevant d20 rolls.
Is this method official?
Yes — 4d6-drop-lowest is the classic rolling method in the Player's Handbook, alongside the standard array and point-buy options.
Are the dice fair?
Yes. Each die uses crypto.getRandomValues for an unbiased 1-in-6 result, just like a well-balanced physical die.
