Uncanny Intuituion

You have an uncanny intuition as to what is about to happen in the immediate future.

• Increase your Dexterity score by 1, to a maximum of 20.
• You cannot be surprised while you are conscious.
• You have a feeling when something you do is about to fail, and can sometimes take the necessary precautions to attempt to succeed. Once per long rest, you can choose to roll the d20 again for one ability check, saving throw or attack roll and choose either roll. You can choose to do this after the roll, but before the roll's outcome has been determined.
