Watery Blade

You evoke a surprisingly sharp watery blade in your free hand. The blade is similar in size and shape to a scimitar, and it lasts for the duration. If you let go of the blade, it disappears, but you can evoke the blade again as a bonus action. 

You can use your action to make a melee spell attack with the watery blade. On a hit, the target takes 2d6 slashing damage. Damage done with this spell is considered magical. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for every two slot levels above 1st.
