You open a gateway to the dark between the stars, a region infested with unknown horrors. A 10-foot-radius sphere of blackness and bitter cold appears, centred on a point you can see within range lasting for the duration.

The void is filled with a cacophony of soft whispers and slurping noises that can be heard up to 30 feet away. The void creates a warp in the fabric of space, and the area is difficult terrain. No light, magical or otherwise, can illuminate the area, which is heavily obscured by the mystical blackness for the duration, and creatures fully within the area are blinded.

Any creature that enters within 10 feet of the spell’s area for the first time on a turn or ends its turn there must succeed on a Dexterity saving throw or take 2d6 acid damage as milky, otherworldly tentacles rub against it and pulls it 10 feet towards the sphere’s center. Also, when a creature moves inside the area, it takes 1d4 cold damage for every 5 feet it travels.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the radius of the sphere increases by 5 feet and the acid damage increases by 1d6 for each spell level above 3rd.
