A bright spark of lightning flashes from your pointing finger to a point you choose within range and then brightens with a low boom into a sphere of crackling electricity. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 5d6 lightning damage on a failed save, or half as much damage on a successful one.

The lightning does not spread around corners. Creatures who wear metal armour have disadvantage on their saving throw.
