Unlike other Hand spells, this does not actually create a visible hand.
The subject of the spell is stunned and falls prone, unable to do anything but wriggle and moan softly. (Falling prone may have other consequences, such as winged flyers plummeting to the ground and swimmers starting to drown.) Eunuchs and targets wearing Belts of Chastity or similar magic items are unaffected by this spell.
Material component: A wooden stick at least 9 and a half inches long.
