Unseen Staff

This spell creates 8 invisible Medium forces that can perform simple tasks at your instruction until the spell ends. The servants spring into existence in an unoccupied space on the ground within range. They have an Armor Class of 10, 1 Hit Point, a Strength of 4, and a Move of 30. The servants cannot attack or deal damage. If it drops to 0 hit points, the servant is destroyed.

The servants can perform any simple tasks that a human servant could do, such as fetching things, cleaning, mending, folding clothes, lighting fires, serving food, pouring wine, basic cooking and cleaning. Once you give the instructions, the servants perform their tasks to the best of their ability until they complete the task, then wait for your next command or set of instructions. The servants are capable of following simple instructions, like refilling any person's glass that asks for more wine, or serve the food as it becomes ready, or keep the area clean. The servants can use simple tools for completing their tasks. The caster is aware of any of the servants who are finished with their tasks or don't have anything to do and can silently provide them with new instructions.

If you command a servant to perform a task that would move it outside the spell's area of effect it is destroyed. 

At Higher Levels. If you cast this spell using a spell slot of 4th level or higher it creates an additional 8 unseen staff members for each level.
