Chosen

You have been touched by either Fate or a God specifically ( this feat is given by a DM and is not a feat a Player can take)

• You have 1 luck point. 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 point when you finish a long rest.
• If you have the Lucky Feat this adds one more point to your daily use

This feat allows a DM to cause events to happen to the character and effect the Character in various ways to fit the story.
