Headbash

You attempt to telekinetically lift two targets within range and slam them into each other. The targets of this spell must be within 30 feet of each other.

Each target makes a Strength save. Creatures that are Huge or larger automatically succeed on the save. On a success, they remain where they are. On a failure, they are pulled in a line towards the other target until they meet, where they fall Prone. For each creature who failed their save, both targets take 18 (4d8) bludgeoning damage.

Using a Higher-Level Spell Slot: The damage increases by 2d8 for each level above 4th.
