Akhenen's Lightless Void

You separate a 30-foot sphere space centered on a point within range that you can see from the rest of existence. Any creatures within this area when the spell is cast are automatically dragged into the new space. Within this space, there is no air, light, heat, or gravity. Creatures are effectively blinded, even if they are normally immune to such effects, and they take 5d12 cold damage at the beginning of each of their turns while inside the space. Moving out of the affected space requires a Strength saving throw, if failed the creature cannot move outside the space.
