Water Cannon

You blast a jet of water with the power of a dragon.  

Make a ranged spell attack against a target object or creature. On a hit the target takes 1d8 bludgeoning damage and is moved 10 feet away from you.

• If you cast this spell while underwater you can also move yourself 10 feet away from the target.
• If you dash while swimming, you can use this cantrip as a bonus action to increase your swim speed by 10 feet, instead of attacking a target.
• If you cast this spell as you move to the surface of a body of water, you can blast yourself 10 feet into the air.

This spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
