Unseen Entourage

This spell creates two intelligent, shapeless, Medium forces area that perform tasks at your command until the spell ends. The servants springs into existence in an unoccupied space on the ground within range. They can be either invisible or take on a form of your choosing that is Medium sized. If visible they appear obviously magical and emit dim light in a 5 foot radius. They have AC 10, 1 hit point, Intelligence of 10, and a Strength of 2, and they can't attack. If their hit points drop to 0, the spell ends.

Once on each of your turns as a bonus action, you can mentally command the servants to move up to 30 feet and interact with an object. The servants can perform tasks that a human servant could do, such as fetching things, cleaning, mending, folding clothes, lighting fires, serving food, and pouring wine independent of each other. Once you give the command, the servants performs their tasks to the best of their ability until they completes the tasks, then waits for your next command.

If you command the servants to perform a task that would move it more than 60 feet away from you, the spell ends.

Shared Intelligence:

  One of the two servants can be commanded to read a book, study a map, or otherwise gain knowledge through a similar means and retain it's contents while you sleep. You must sleep for 6 hours while the servant reads the book. Once awake you can end the spell and gain the knowledge learned by the servant, both servants will be dispelled when you do this. 

Once per short rest, as an action you can choose to dismiss one of your servants and absorb their intelligence. Absorbing a servant's intelligence grants you advantage on the next Intelligence Ability Check or Intelligence Saving Throw. If only one servant remains, recasting the spell will create a second servant. 

Loyal Servants:

You can command your servants to patrol an area and act as guards against unwanted intrusion. Choose an area within range that is no larger than a 20-foot cube. Until you command them to stop, the servant(s) will alert you telepathically whenever a Tiny or larger creature enters the chosen area. When you give the command, you can designate creatures that can enter the chosen area. If you are asleep when they alert you, the telepathic alert wakes you up.
