Charger

When you use your action to Dash, you can use a bonus action to make one melee weapon attack or to shove a creature. If you choose to make a melee weapon attack, and have the Extra Attack feature, you may make a number of extra melee weapon attacks equal to what has been granted by that feature.

If you move at least 10 feet in a straight line immediately before taking this bonus action, you either gain a +5 bonus to the first attack that hits‘s damage roll (if you chose to make a melee attack and hit) or push the target up to 10 feet away from you and knock it prone (if you chose to shove and you succeed).
