Using your winged arms, you can slow your fall, and glide short distances. When falling you can use your reaction to spread your arms, stiffen your wings, and slow your descent. While doing so, you continue to fall gently at a speed of 60 feet per round, taking no fall damage when you land. If you would fall at least 10 feet in this way, you may fly up to your movement speed in one direction you choose, although you cannot choose to move upwards, landing in the space you finish your movement. You cannot glide while carrying heavy weapons or wielding a shield (though you may drop any held items as part of your reaction to spread your arms). You cannot glide while wearing heavy armor, or if you are encumbered.

You can see in dim light within 60 feet of you as if it were bright light and in darkness as if it were dim light. You discern colors in that darkness as shades of gray.

You have sharp fangs that enable you to make natural bite attacks. You can choose to bite as an unarmed strike that deals 1d6 points of piercing damage, which can be calculated using either your Strength or Dexterity modifier for both the attack roll and damage bonus.

You can heal yourself with this bite a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

You can speak, read, and write Common and Auran.
