Conjure Barrage

Conjuration
Level: 3rd
Casting Time: 1 action
Range: Self (60-foot cone)
Components: V, S, M (one piece of ammunition or a thrown weapon)
Duration: Instantaneous

You throw a non-magical weapon or fire a piece of non-magical ammunition into the air to create a cone of identical weapons that shoot forward and then disappear. Each creature in a 60-foot cone must succeed on a Dexterity saving throw. A creature takes 3d8 damage on a failed save, or half as much damage on a successful one. The damage type is the same as that of the weapon or ammunition used as a component.
