Urano Metria

You call upon the might of the starry sky through these words:
"Survey the Heavens, Open the Heavens...
All the stars, far and wide, Show me thy appearance...
With such shine.
Oh Tetrabiblos, I am the ruler of the stars...
Aspect become complete, Open thy malevolent gate.
Oh 88 Stars of the Heaven, Shine!
Urano Metria!"

Manifested through the air are satellites, down-sized copies of celestial bodies.
They surround and center around the target in a 12 ft/4 m radius.
As they rush toward them, they crash like meteorites.
You roll 4d8 of bludgeoning, 4d8 of force & 4d8 of radiant damage.
If they fail their Dex save, they end up unconscious.
