Tempestuous Sphere

A sparking globe of volatile energy streaks from your fingertips to a point of your choice within range, where it detonates in a 50-foot-radius sphere of lightning and thunderous power.

Each creature in the area must make a Constitution saving throw. On a failed save, a creature takes 4d8 lightning damage and 4d8 thunder damage and is paralyzed for 1d4 rounds. On a successful save, the creature takes half as much damage and is not paralyzed.

• Water Interaction: If the globe strikes a body of water or a liquid primarily composed of water, the lightning damage spreads up to 100 feet through the water, affecting all creatures standing or swimming in it. Creatures in the water must make the same saving throw but do so with disadvantage.

At Higher Levels

When you cast this spell using a spell slot of 7th level or higher, the lightning and thunder damage each increase by 1d8 for every slot level above 6th.
