Water Canon

A pressurised container dissapears from your hand and reappears at a point you can see within range and then detonates with a low roar into an explosion of water. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 bludgeoning damage and is pushed back 15ft from the centre of the blast on a failed save, or half as much damage taken on a successful one and they are not pushed.

The explosion of water spreads around corners and it douses all flames in the area.

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