Countershot

You hone your ability to cut enemy projectiles out of the air. 

• Increase your Dexterity score by 1, to a maximum of 20.
• When you are targeted by a ranged weapon attack while you are holding a weapon with the finesse property or a ranged weapon, you can make an attack against the projectile. If the result is greater than that of the attack targeting you, you halt or deflect the projectile and the attack doesn't hit.
