Abythos's Void Sinkhole

You call upon Abythos, God of the Void, tearing open a 20-foot-radius sphere of crushing gravitational force at a point you can see within range. The void's hunger tugs at creatures inside, who must each make a Constitution saving throw.

On a failed save, a creature takes 5d10 force damage and is pulled in a straight line to the sphere's center, landing in the closest unoccupied space (even if airborne). If this leaves it 20+ feet above the ground with no support, it falls at the end of its next turn, taking normal falling damage. On a successful save, a creature takes half damage and isn't pulled.
