EMP

A bright streak flashes from your pointing finger to a point you choose within range and then blossoms with a electrically charged explosion. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 lightning damage on a failed save, or half as much damage on a successful one.

It does 6d4 bonus damage to constructs.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d12 for each slot level above 3rd.
