Charge

Prerequisite: Cavalier mount or animal companion

Whenever the mount uses its action to Dash. It can use its bonus action to make one melee attack or to shove a creature. This attack must happen at the end of the mount's moevement.

If the mount moves at least 10 feet in a straight line immediately before taking this bonus action, it either gains a +5 bonus to the attack's damage roll (if it chose to make a melee attack and hit) or pushes the target up to 10 feet away (if it chose to shove and succeeds).

If the mount move at least 10 feet in a straight line and doesn't attack or shove, its rider gains advantage on his or her first attack roll and a +5 bonus to the damage roll, provided this is a melee weapon attack.
