How to roll ability scores: every method compared

Rolled stats are exciting; fixed arrays are fair. Here's how each method works, what to expect from the dice, and how to pick one for your table.

In short

4d6 drop lowest: roll four d6, drop the lowest, six times (average 12.24 per score, high variance). Standard array: 15, 14, 13, 12, 10, 8 (fair, quick). Point buy: start at 8, spend 27 points up to 15 (customizable, fair). Ask your DM which one to use.

Method 1: 4d6 drop lowest

Roll four d6, ignore the lowest die, add the other three. Do it six times and assign the results to abilities.

  • Average per score: 12.24
  • Chance of an 18: ≈1.6%; chance of 3: ≈0.08%
  • Most common results: 12 and 13

Pros: exciting, occasionally heroic scores. Cons: one player might roll far better than another. Some tables allow a reroll if the total modifiers are too low, or have everyone use the same shared rolled set.

Roll a full set in one tap with the character sheet creator, or roll 4d6dl1 in the dice roller.

Method 2: Standard array

Assign 15, 14, 13, 12, 10, 8 however you like. It's fast, fair, and what most organized-play games use.

Method 3: Point buy

Every score starts at 8 and you have 27 points. Scores can go up to 15 before bonuses.

Score 8 9 10 11 12 13 14 15
Cost 0 1 2 3 4 5 7 9

Popular spreads:

  • 15, 15, 15, 8, 8, 8: three strong stats, three dump stats.
  • 15, 15, 13, 10, 10, 8: focused but flexible.
  • 15, 14, 13, 12, 10, 8: the standard array.

Other methods you'll see

  • 3d6 in order: old-school and unpredictable; you play what you roll.
  • Heroic arrays: 16, 15, 14, 13, 12, 10 for higher-powered games.
  • Rolling 4d6 but rerolling 1s: a house rule that pushes scores higher.

FAQ

Questions, answered

Still curious? The app's help section and store listing have more.

What is the average of 4d6 drop lowest?

About 12.24 per ability score. A full set of six rolled scores averages a little over 73 total, slightly above the standard array's 72.

What's the chance of rolling an 18 with 4d6 drop lowest?

About 1.6% per score (21 of 1,296 outcomes), so roughly a 9% chance of at least one 18 in a set of six.

Is point buy better than the standard array?

Point buy offers more choice; the standard array is one valid point-buy result (it costs exactly 27 points). Both keep characters balanced.
