Clockwork Task

You create a six second loop of your last action. When you cast this spell, a formless, invisible entity is created in your place. The entity can perform simple tasks that a human could do, such as opening/closing doors, pushing buttons, throwing levers, and other simple motions. Only one entity may be active at a time. If you cast Clockwork Task a second time, the original spell is dispelled.  (This spell shares the same entity as Secluded Function.)

If a creature uses its action to examine the area, the creature can determine that it is a spell with a successful Intelligence (Investigation) check against your spell save DC.

[This spell is intended to be equivalent to Unseen Servant]
