Battlefield Commander

You dominate the battlefield through perfect tactical awareness. For the duration, hostile creatures of your choice in the emanation treat the area as difficult terrain. Once on each of your turns, when you hit a hostile creature with a weapon attack, you may choose one additional hostile creature within 10 ft. of the target. That creature must make a STR save or be knocked prone, pushed 15 ft., disarmed, or unable to take reactions until the start of your next turn.
