You create a massive storm cloud centered on a point you can see, spreading in a 360-foot radius. Lightning flashes, thunder booms, and strong winds roar beneath it. When the cloud appears, each target under it, up to 5,000 feet below, must make a Contesting Fortitude Roll. On a failure, the target takes 2d6 thunder damage and becomes deafened for 5 minutes.

Each round you maintain concentration, the storm produces a different effect on your turn:

1. Round 2 — Acid Rain: Each creature and object under the cloud takes 1d6 acid damage.
2. Round 3 — Lightning Bolts: You call down six lightning bolts, each striking a different creature or object beneath the cloud. A struck creature makes a Contesting Balance Roll, taking 10d6 lightning damage on a failure or half damage on a success.
3. Round 4 — Hailstorm: Hailstones fall from the cloud. Each creature under it takes 2d6 bludgeoning damage.
4. Rounds 5–10 — Freezing Storm: Gusts and freezing rain fill the area beneath the cloud. The area becomes difficult terrain and heavily obscured, and each creature there takes 1d6 cold damage. Ranged weapon attacks in the area are impossible, and the storm severely disrupts concentration. The strong winds also disperse fog, mist, and similar effects, whether mundane or magical.
