Aquatic Limb

Create a water appendage that protrudes from the casting creature. The limb can manipulate objects, such as opening an unlocked door, pouring liquid out of vials and carrying small objects weighing no more than 5 lbs. All objects manipulated in this way become extremely wet. 

As a bonus action, you may use the limb to make a melee spell attack against any creature within 10 ft. This attack deal 1d4 bludgeoning damage + your spellcasting modifier. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d4 for every two slot levels above 1st.
