Bigby's Middle Finger

Conjure a giant, ethereal, purple middle finger. This finger is holographic, meaning it cannot be touched or touch anything else. All creatures that see it must pass a DC 10 Wisdom Saving Throw or be knocked Prone. After the duration of the spell, a smaller holographic hand appears, does a motion to indicate winding up a music box, and the middle finger curls back up, then both conjurations pop out of existence.
