Event Horizon

Light warps and disappears as you create the ultimate destructive force, a black hole. A 5-foot-radius sphere of immense gravity appears, centered at a point within range and lasting for the duration. No light, magical or otherwise, can illuminate the area, and creatures fully within the area are blinded.

The black hole has immense gravitational pressure and crushes anything within the sphere. A creature that starts its turn in the area or enters the area for the first time on its turn takes 27 (5d10) force damage. Additionally, the black hole's gravity attempts to pull everything nearby into the black hole. Any creature that begins its turn within twice the radius of the starting sphere must succeed a Strength saving throw or be pulled 10 feet closer to the sphere. Also, while within the radius, moving directly away from the black hole is considered difficult terrain, however, moving directly toward the black hole costs half as much movement. All ranged attacks that use ammunition are made at disadvantage. Any objects not being carried or worn, bolted down, or heavy enough to withstand the gravitational pull are pulled into the blackhole. 

When casting this spell at higher levels, the radius of the sphere increases by 5 ft.
