Bountiful Luck XGE p73
Prerequisites: Halfling
Your people have extraordinary luck, which you have learned to mystically lend to your companions when you see them falter. You're not sure how you do it; you just wish it, and it happens. Surely a sign of fortune's favor!
When an ally you can see within 30 feet of you rolls a 1 on the d20 for an attack roll, an ability check, or a saving throw, you can use your reaction to let the ally reroll the die. The ally must use the new roll.
When you use this ability, you can't use your Lucky racial trait before the end of your next turn.
Lucky PHBp167
You have inexplicable luck that seems to kick in at just the right moment.
You have 3 luck points. Whenever you make an attack roll, an ability check, or a saving throw, you can spend one luck point to roll an additional d20. You can choose to spend one of your luck points after you roll the die, but before the outcome is determined. You choose which of the d20s is used for the attack roll, ability check, or saving throw.
You can also spend one luck point when an attack roll is made against you. Roll a d20, and then choose whether the attack uses the attacker's roll or yours. If more than one creature spends a luck point to influence the outcome of a roll, the points cancel each other out; no additional dice are rolled.
You regain your expended luck points when you finish a long rest.
