Halfling Luck is a passive feature in Baldur's Gate 3 that grants all halflings to reroll a dice when it lands on a 1 for an Attack Roll, Ability Check, or Saving Throw.
Description
When you roll a 1 for an Attack roll, Ability check, or Saving throw, you can reroll the dice and must use the new roll.
How to learn
Races:
- Character level 1: Halfling
(Character level is the sum of all class levels for a multi-classed character.)
Notes
- It is possible for the new roll to be another 1.
- As of patch 6, when rolling with advantage, the following rules apply:
- If one dice rolls a 1, it's re-rolled, and the higher of the two dice used.
- If both dice roll a 1, they are both re-rolled, and the higher one used.
- The chance to hit displayed when hovering an attack on an enemy doesn't take into account Halfling Luck.
- Halfling Luck is particularly useful to avoid failures for ability checks and saving throws when the roll would only fail on a critical miss.
- On a normal roll that succeeds on a 2 or more, Halfling Luck would reduce the chance to fail from 1/20 to 1/400.
- On a roll with advantage that succeeds on a 2 or more, Halfling Luck would reduce the chance to fail from 1/400 to 1/160000, making it practically impossible to fail. With Karmic Dice active, it may be simply impossible to roll 4 critical failures in a row.
- Traders can get all their easy to steal item stolen without fear of missing a single roll.
- Be mindful that it can make your character which gives disadvantage on all ability checks, including further pickpocket attempts.
- Stealth checks can get pretty much guaranteed to succeed.
- Also useful to avoid Concentration getting interrupted too often by constitution save critical misses when taking low damage.
Math
Chances of succeeding a specific roll
See Advantage math section for comparison.

Chance to hit comparisons
On a normal roll, Halfling Luck multiplies the chance to hit by :
- 1.05 whatever the target roll is
- This would be the most noticeable for a target roll of 2 which would add a flat 4.75% chance to hit or almost +1 on a d20.
- For a target roll of 20 it would add a flat 0.25% chance to hit, which would be a critical success.
On a roll with Advantage, Halfling Luck multiplies the chance to hit by :
- 1.003 for a target roll of 2 or a flat +0.25% chance to hit
- 1.01 for a target roll of 3 or a flat +0.70% chance to hit
...
- 1.03 for a target roll of 11 or a flat +2.44% chance to hit
...
- 1.05 for a target roll of 20 or a flat +0.47% chance to hit, which would be a critical success.
On a roll with Disadvantage, Halfling Luck multiplies the chance to hit by :
- 1.10 whatever the target roll is
- This would be the most noticeable for a target roll of 2 which would add a flat 9.25% chance to hit or almost +2 on a d20.
- For a target roll of 20 it would add a flat 0.03% chance to hit, which would be a critical success.
Chance to fail comparisons
On a normal roll, Halfling Luck divides the chance to fail by :
- 20 for a target roll of 2
- 1.82 for a target roll of 3
- 1.40 for a target roll of 4
...
- 1.003 for a target roll of 20
On a roll with Advantage, Halfling Luck divides the chance to fail by :
- 400 for a target roll of 2
- 3.31 for a target roll of 3
- 1.95 for a target roll of 4
...
- 1.01 for a target roll of 20
On a roll with Disadvantage, Halfling Luck divides the chance to fail by :
- 19.52 for a target roll of 2
- 1.78 for a target roll of 3
- 1.36 for a target roll of 4
...
- 1.0003 for a target roll of 20
