You have mastered using your wings in combat.

• You can sacrifice one of your attacks to duck low and whirl in place to attempt to knock every creature within 5ft of you prone. They must make a Dexterity saving throw against your DC which is 8 + proficiency + your Strength modifier.
• As long as you have at least half movement from your previous turn, when a creature attempts to knock you prone you can use your reaction to resist the effect.
• If you move at least half of your movement toward a target in a straight line and hit with a melee attack, you can add an extra 1d6 damage to the hit.
• If you have proficiency in heavy armor, you may wear heavy armor and still have your normal flying speed.
