WW: Oppugno

You bring some items laying around to life and they throw themselves at a target in range. Hundreds of duplicates of the object fall in a volley from above and then disappear. Each creature in a 40-foot-radius. 20-foot-high cylinder centered on that point must make a Dexterity saving throw. A creature takes 6d8/Force damage on a failed save, or half as much damage on a successful one.

At higher levels: The damage is increased by 1d8 per level above 4th.
