When you use the Dash action, you can use a bonus action to make a melee weapon attack or shove a creature.
If you move at least 10 ft. in a straight line before using this bonus action, you either gain a +5 bonus to the damage roll (if you chose to make a melee attack and you hit) or push the target up to 10 ft. away from you (if you chose to shove and you succeed).
