Unseen Crafter

Unseen Crafter KT: KCG p144 5th-level conjuration Casting Time: 1 minute Range: 60 feet Components: V, S, M (a bit of string and wood) Duration: 8 hours This spell creates an invisible, mindless, shapeless, Medium force that performs simple tasks at your command until the spell ends. The crafter 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 crafter to move up to 15 feet and interact with an object. The crafter 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. Additionally, it can perform skilled crafting checks. It always uses the taking 10 rule for crafting checks, completing one check every 4 hours. Its crafting modifier is +5. When you summon it, you can summon it with one artisan tool of your choice, which only it can use. It can use any other artisan tools otherwise available. If you cast this spell again while the crafter still exists, the previous one vanishes.
  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. If you command the servant to perform a task that would move it more than 60 feet away from you, the spell ends.
  At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, its crafting modifier increases by 1. Classes: Artificer (Revised), Wizard Note: Both the Fighter (Eldritch Knight) and the Rogue (Arcane Trickster) spell lists include all Wizard spells. Spells of 5th level or higher may be cast with the aid of a spell scroll or similar. Source: KT: KCG, page 144
