[RPG] How many luck points does it cost to get a better attack roll with Lucky

dnd-5efeats

For the Lucky feat there is something I need clarified. The feat says (PHB p. 167):

"… 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 d20 is used
for the attack roll, ability check, or saving throw…"

My DM interprets this as:

  1. Spend 1 luck point to roll a d20
  2. Spend 1 more luck point to replace a d20 roll with the new "lucky roll" if you want… otherwise you have used up only 1 point to roll the d20

I always read it as:

  1. Spend 1 point, roll a d20 for luck. Replace the old roll with no additional cost

What is correct?

Your DM is wrong.

The ability wouldn't have 3 points if you had to spend 2 to use it once. The confusion in the wording is the second sentence. All it does is clarify when the luck point can be spent.

Example:

You are climbing a mountain and there's a rockslide, the DM says, "Make a DEX save to see if you get knocked off."

You roll a fail on your save. Instead of taking the fail, you can spend a luck point to see if the gods of luck are with you and help you make your save. You roll another D20 as your save, and you choose which of the two you take for your roll.
