This spell creates an invisible, mindless, shapeless force that performs simple tasks at your command until the spell ends. The servant springs into existence in an unoccupied space on the ground within range. It has AC 10, 1 hit point, and a Strength of 2, and it can't attack. If it drops to 0 hit points, the spell ends.
Once on each of your turns as a bonus action, you can mentally command the servant to move up to 15 feet and interact with an object. The servant can perform simple tasks that a human servant could do, such as fetching things, cleaning, mending, folding clothes, lighting fires, serving food, and pouring wine. Once you give the command, the servant performs the task to the best of its ability until it completes the task, then waits for your next command.
One thing glaringly missing from this write-up is the servant's weight, if any; which is a highly relevant property.
If the servant is weightless then it could in theory float uncontrolled, though not fly in the usual sense, and be towed or pushed like a balloon. I could think of all kinds of uses for this.
If the servant has weight it can be used as a trap finder by having it "walk" ahead of the party to set off pressure plates, trip wires, etc.
Also, "shapeless" isn't very helpful if someone can see invisible and can thus see the servant - what does the bloody thing look like?
