Astral Impact

You tap into the fabric of the astral plane, infusing your roundhouse kicks with ethereal power. For the duration of the spell, your unarmed roundhouse kick attacks deal an additional 6d8 force damage.

Additionally, whenever you hit a creature with a roundhouse kick, they must succeed on a Strength saving throw or be banished to the Astral Plane until the end of their next turn. At the end of their turn, they return to the space they previously occupied or the nearest unoccupied space if that space is occupied.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the additional force damage increases by 1d8 for each slot level above 4th.
