Blitz Strike

Prerequisite – 11th level

When you make a whirlwind attack action, you can expend two superiority dice to modify the action. When you do, whirlwind attack’s range changes to a line 45 feet long and 10 feet wide, and each creature you would make a melee attack against instead must make a Dexterity saving throw. Creatures who fail their saving throw suffer the whirlwind attack’s normal effects plus damage equal to two rolls of your superiority die. Creatures who succeed their saving throw take half of that damage. Provided your movement speed isn’t zero, you may then move to an empty square in the line without provoking attacks of opportunity.
