Psychic energy emerges from the ground in a 40ft, centered on you. Begininng at the end of your turn, for three rounds, all grounded creatures in the affected area are unable to use bonus actions. Grounded creatures are those that do not have a flying speed or Levitate, Magnet Rise, or similar ability. In addition, creatures may double their MOVE modifier on damage rolls from psychic-type moves activated inside the area.
