All the Sand, All the Stars

You force your foe to see all the grains of sand in the desert and all the stars in the heavens. It reels in shock, unable to grasp infinity. One creature within 60 ft of you makes a wisdom saving throw and takes 5d12 psychic damage on a failed save or half that on a successful save. The target also becomes paralyzed on a failed save and can make an additional wisdom saving throw at the end of each of its turns, a successful save ends the paralysis.
