Your Luck Point capacity equals your Proficiency Bonus. A Long Rest restores all spent points.
Spend 1 point when you roll a d20 for a D20 Test to give yourself Advantage on that roll. Alternatively, spend 1 point when another creature rolls a d20 for an attack against you to impose Disadvantage on that attack roll.
