Flight doesn't just come naturally to you, it is an art form, granting you the following benefits:

• Increase your Dexterity by 1, to a maximum of 20.
• If while airborne you are forced to take a saving throw that, on failure, will cause you to become Restrained, Paralyzed or Prone, you may instead choose to make a Dexterity (Acrobatics) check in place of the normal saving throw.
• You have advantage on Acrobatics and Perception checks taken while airborne during your own turn.
