Water Hammer

You evoke a water hammer in your free hand. The weapon is similar in size and shape to a warhammer, and it lasts for the duration. If you let go of the hammer, it disappears, but you can evoke the hammer again as a bonus action.

You can use your action to make a melee spell attack with the water hammer. On a hit, the target takes 3d6 bludgeoning damage.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for every two slot levels above 2nd.
