Tatami-Gaeshi

Conjures a long, heavy tatami mat that falls in front of you. All creatures in a 25 foot long line before you must roll a STR saving throw or take 3d4 bludgeoning damage. The closest creature hit will instead take bludgeoning damage equal to 4d6 plus your spellcasting modifier on a failed save. On a failed save, creatures are also stunned until the end of their next turn.
