Electro Wave

A wave of Electrostatic Lightning force sweeps out from you. Each creature in a 20-foot sphere originating from you must make a Constitution saving throw. On a failed save, a creature takes 5D8 Lightning damage and is paralyzed for 3 Rounds. On a successful save, the creature takes half as much and isn't paralyzed.

In addition, unsecured objects that are completely within the area of effect are automatically pushed 10 feet away from you by the spell's effect, and the spell emits a electrostatic lightning crack audible out to 200 feet.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1D8 for each slot level above 4th.
