You have inexplicable visions that seems to kick in at just the right moment. Each vision is only visible to you, and happens nearly instantaneously, with the scene happening in your minds eyes. The visions are potential futures in which you tried something that didn't work, failed, or had a critical accident that deterred you or your friends. The content of your vision fills your mind with new knowledge and experience,  potentially allowing you to turn a failure into a success at the last moment.

• You have 2 clairvoyance points. Whenever you make an attack roll, an ability check, or a saving throw, you can spend one clairvoyance point to roll an additional d20. You can choose to spend one of your clairvoyance 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 clairvoyance 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.
• You regain your expended clairvoyance points when you finish a long rest.
