Knight's Charge

Your training with combat atop amount has made you a deadly threat.  On your turn, you can use your bonus action to allow your mount to move its speed as a reaction.  If the mount moves 10 feet in a straight line towards a target in this way, you either gain a +5 bonus to the attack’s damage roll (if you chose to make a melee attack and hit) or push the target up to 10 feet away from you (if you chose to shove and you succeed).  If the mount moves this way, it can only move half its movement during its turn.
