Maneuvering Attack

When you hit a creature with a weapon attack,
you can expend one superiority die to maneuver
one of your comrades into a more advantageous
position. You add the superiority die to the
attack's damage roll, and you choose a friendly
creature who can see or hear you. That creature
can use its reaction to move up to half its speed
without provoking opportunity attacks from
the target of your attack.
