If you jump at least 15 feet as part of your movement, you can then use your action to land on your feet in a space that contains one or more other creatures. Each of those creatures must succeed on a DC (12+your Str Mod+Your PB) Strength or Dexterity saving throw (target's choice) or be knocked prone and take 1d6 bludgeoning damage plus 1d6 slashing damage. On a successful save, the creature takes only half the damage, isn't knocked prone, and is pushed 5 feet out of the your space into an unoccupied space of the creature's choice. If no unoccupied space is within range, the creature instead falls prone in your space.
