Fatebound

You've gained some level of awareness when determining cause and effect of your personal actions allowing you to bend your own fate in dire times. 

• You have fate points. Whenever you make an attack roll, an ability check, or a saving throw, you can spend one fate point to roll an additional d20. You can choose to spend one of your fate 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 fate 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 fate point to influence the outcome of a roll, the points cancel each other out; no additional dice are rolled.
• You regain your expended fate points when you finish a long rest.
