Waterball

You hurl a soaking-wet sphere of condensed water droplets at a point you choose within range. When the sphere impacts, it explodes in a 20-foot-radius sphere, drenching everything in the area with a sudden burst of icy water. It deals 8d6 cold damage.

Saving-Throw: Dexterity; a successful save halves the damage.

All nonmagical flames within 20 feet (candles, torches, campfires, etc.) are extinguished

The ground in the area becomes difficult terrain (slippery) until the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 cold damage for each slot level above 3rd.
