Dearthenick's Duplicitous Duplicates

This spell creates three duplicates of you, which spring into existence in unoccupied spaces on the ground within range. Each duplicate has AC equal to 10 + your Dexterity modifier, 10 hit points, a Strength of 2, and cannot attack. If a duplicate drops to 0 hit points, it is destroyed. The spell ends when all three duplicates are destroyed. Each duplicate shares your Intelligence, Wisdom, and Charisma scores, as well as skill proficiencies.

Once on each of your turns as a bonus action, you can mentally command each duplicate to move up to 15 feet and interact with an object. A duplicate can perform a multitude of simple tasks, using your skill proficiencies. Examples include assisting in research or crafting tasks, copying new spells, fetching things, mending, cleaning, etc. Once you give the command, the duplicate performs the task to the best of its ability until it completes the task, then waits for your next command.

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

When the spell ends, each duplicate dissipates into green smoke. When a duplicate dissipates, the smoke swirls around the caster, and any knowledge the duplicate gained is passed on to you. When all three duplicates have passed on their knowledge, you must succeed on a DC 15 Intelligence saving throw, or suffer one level of exhaustion, as your brain has just received three times the knowledge it normally would have in the same time frame.
