Flight of the Faerie

You’ve manifested the confounding magic emblematic of teleportation:

Ability Score Increase. Increase your Wisdom or Charisma score by 1, to a maximum of 20.

Fae Escape. When a creature you can see tries to hit you with a physical attack roll, you can use your reaction to vanish. You then teleport to an unoccupied space that you can see within 30 feet of yourself, leaving behind an illusion. You can use this reaction a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
