D&D Stat Roller

Free D&D 5e ability score roller: 4d6 drop lowest with every die shown, 3d6 classic, 2d6+6 heroic, the 27-point point buy calculator, and standard array assignment — all with live modifiers.

Roll Your Ability Scores

Three Official Ways to Make a Character

The Player's Handbook offers three routes to ability scores, and this tool implements all of them faithfully. 4d6 drop lowest is the classic: exciting, swingy, and the reason half of all fighters have one mysterious 5 in Intelligence. Point buy gives every player the same 27-point budget — the tournament-fair option. Standard array skips the math entirely with the fixed 15/14/13/12/10/8 spread. Every mode shows live ability modifiers, and one click copies the finished line into your character sheet or session-zero chat.

The Real Odds of 4d6 Drop Lowest

These probabilities are enumerated from all 1,296 possible four-dice outcomes — the exact chance of each score, not a simulation. The mean is 12.24; an 18 comes up on about one roll in 62, so a full character has roughly a 9% chance of at least one natural 18.

House Rules the Roller Supports

Playing 3d6-in-order old-school style? Use the 3d6 tab and assign top to bottom. Running a heroic campaign? 2d6+6 guarantees no score below 8 while keeping some randomness. And if the table rules “reroll the whole set if the total is under 70”, the set total is displayed under every roll — compare it against the standard array's 72. For everything else your session needs, the dice roller handles arbitrary d4–d100 pools.

Frequently Asked Questions

How does 4d6 drop lowest work?

Roll four six-sided dice, drop the lowest one, and add the remaining three — repeat six times for six ability scores. The roller shows all four dice with the dropped one crossed out, so every score is verifiable at the table.

What is the average roll for 4d6 drop lowest?

Exactly 12.24 per ability score — noticeably above the 10.5 average of plain 3d6, which is why most tables use it. A full set of six scores averages around 73.5 total, just above the standard array's 72.

How does point buy work in D&D 5e?

You get 27 points and every score starts at 8. Raising a score costs its listed price: 9–13 cost 1 point per step, 14 and 15 cost 2 per step (7 and 9 points total). The calculator enforces the budget and the 8–15 range and shows your remaining points live.

What is the standard array?

15, 14, 13, 12, 10, 8 — the fixed set of scores the Player’s Handbook offers for players who want speed and fairness over dice drama. Use the arrows in the Standard Array tab to swap the values between abilities until they fit your class.

Is rolling better than point buy?

Statistically, yes on average — 4d6 drop lowest expects about 1.5 more total points than point buy can produce. But the variance cuts both ways: roughly one set in ten is worse than the all-8s point-buy floor... Rolling is a gamble, point buy is a guarantee; ask your DM which the table uses.
