Mounted Archer

While you are mounted and aren't incapacitated you gain the following benefits:

• Being within 5 feet of a hostile creature doesn’t impose disadvantage on your ranged attack rolls.
• If you are attacked by a ranged attack outside of your short range you can use your reaction to make a counter-attack targeting the projectile, the projectile's AC is equal to the attack roll made on you, and hit points are equal to the damage it will deal. If reduced to 0 hit points you take no damage.
• If your mount is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.
