| * As of patch 6, when rolling with advantage, the following rules apply:
| |
| ** If one die 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 {{SAI|Heavily Encumbered (Condition)|Heavily Encumbered}} 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.

| === 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.
