Your bending attack modifier for maneuvers is the attack modifier of the elemental bending or weapon attack you make in conjunction with the maneuver.

Some are gifted with natural talent or ability, others fight tooth and nail for every inch they gain. Some focus on breaking down their opponents with superior technique, some look for ways to counter the techniques, and others use raw power to punch right through.

If the creature can see or hear you, it must succeed on a Wisdom saving throw (DC equal to 8 + your proficiency bonus + your Charisma modifier) or be charmed by or frightened of (your choice) you until the end of your next turn. On subsequent turns, you can use your action to extend the duration of this effect on the frightened creature until the end of your next turn.
