9th-level / White Raven
With a great battle cry, you lead your allies in a devastating charge. Fired by your commanding presence and deftly led by your supreme grasp of tactics, you and your allies form an unstoppable wedge. As part of this maneuver, you charge an opponent using up to your speed. All allies within 30 feet of you can use their reaction to also charge the same enemy. They can move up to their speed on a direct route towards the target. You and your allies do not provoke attacks of opportunity for moving as part of this charge. Every creature that charged your target (including you) can then immediately make an attack against the target. Attacks made this way have a bonus to their attack roll equal to the number of creatures that charged and deal an additional 6d6 damage. If the target was hit by two or more attacks of this charge it must succeed on a Constitution saving throw or be stunned until the end of its next turn.
