Cosmic Rift

You tear open a rift to the chaotic realms of the Elder Gods. Choose a point within range; a rift appears in a 10-foot radius centered on that point. The rift is filled with writhing, alien energy that affects all creatures within it. Each creature within the area must make a Constitution saving throw. On a failed save, a creature takes 6d6 psychic damage and is pulled 10 feet toward the center of the rift. On a successful save, it takes half the damage and is not pulled. The chaotic nature of the spell causes unpredictable effects; roll a d6 at the end of each of your turns while concentrating on this spell. On a 1-2, you take 1d10 psychic damage.
