When you're within 5 feet of a creature on your turn, you can expend one superiority die and switch places with that creature, provided you spend at least 5 feet of movement and the creature is willing and isn't incapacitated. This movement doesn't provoke opportunity attacks. Roll the superiority die. Until the start of your next turn, you or the other creature (your choice) gains a bonus to AC equal to the number rolled.
When you hit a creature with a weapon attack, you can expend one superiority die to attempt to frighten the target. You add the superiority die to the attack's damage roll, and the target must make a Wisdom saving throw. On a failed save, it is frightened of you until the end of your next turn.
When you hit a creature with a weapon attack, you can expend one superiority die to attempt to drive the target back.
