Dregan's Penultimate Puppetry

You hold the strings of life for a brief moment, animating a fallen or unconscious creature to fight for you. The target creature immediately rises to its feet with an additional 1d6 temporary hit points and moves its speed towards the nearest enemy of yours, using its action to make a single weapon attack or cast a cantrip that it knew in life (your choice).

At the end of the spell, the creature falls back to the ground, unconscious or lifeless if it was dead before the spell was cast. Using this spell on a creature that is unconscious counts as a failed death save.

When you cast this spell using a spell slot of 4th level or higher, the duration increases by 1 round for each spell slot above 3rd.
