Three-Quarterling

You gain 2 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.
• You gain an additional Luck point at Barbarian level 6, and again at level 12

Your Luck points can also be used to effectively cast Longstrider, or Pass Without Trace

You gain 1 druid cantrip of your choice
