Ki Defense

You have been experimenting with the energy of Ki, and realized that if you focus some into your hand, you can sometimes block small projectiles. You can use Ki as a second line of defense, before an enemy rolls an attack roll against you, you can choose to spend a Ki point to try to counter their roll. If you spend a Ki point, roll a DC 20 + your proficiency bonus. If your roll is higher than the attack roll of the enemy, the missile is deflected. This only works with small, non-magical projectiles like arrows or rocks.
