Casting Time: 1 action
Range/Area: 120 feet
Components: V, S
Duration: Concentration, up to 1 minute
You conjure an eruption of force in the future. Choose a point within range to be the center of the explosion, which can’t be detected. When your concentration on this spell ends, a 30-foot-radius sphere centered on the chosen point erupts with power. Each creature in the area must make a Constitution saving throw. A creature takes 5d8 force damage on a failed save, or half as much on a successful one.
At higher levels: When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d8 for each slot level above 4th.
