Ether's Blistering Void

A dark void appears from your pointing finger to a point you choose within range and then blossoms into a silent, violent implosion. A small ball of noiseless black followed by a sudden and violent movement of people. Each creature in a 15-foot-radius sphere centered on that point must make a Dexterity saving throw, or be violently pulled towards the center of the sphere and suffer 8d6 Force damage on a failed save, or half as much on a successful save.

After this effect, the targets must all make a Strength saving throw or be knocked prone on a failed save after the damaging effect.
