You manifest a mote of Hell on the Mundane world. A 15-foot radius sphere of darkness, brimstone, and blasting heat arrives, centered on a point within range and lasting for the duration of the spell. The cloud of hellfire echoes with the cries of damned souls that can be heard by anyone within 30 feet of the cloud.   No light, even magical light, can illuminate the area and any creatures fully within the area are blinded. The cloud warps the timescape and the area is difficult terrain. Any creature that starts its turn in the area takes 2d6 fire damage. Any creature that ends its turn in the area must succeed on a Wisdom saving throw or take 2d6 psychic damage as the voices of the damned crowd their mind.
