Wall of the Endless Void

You tear open reality, revealing an endless void between worlds. You create a wall of writhing darkness at a point within range. The wall appears as a vertical plane of black emptiness filled with ghostly, clawing hands. The wall can be up to 60 feet long, 20 feet high, and 1 foot thick, or a 20-foot-radius ring. When the wall appears, choose which side is the safe side. The opposite side becomes the hungry void.

Hungry Void

When a creature starts its turn within 10 feet of the dangerous side of the wall, spectral hands burst outward to seize it. The creature must make a Strength saving throw. On a failure:

• The creature takes 6d8 necrotic damage

• The creature becomes Grappled (escape DC = your spell save DC)

• While grappled, the creature is Restrained as the hands claw and strangle it.

A creature takes 2d8 necrotic damage at the start of each of its turns while restrained this way. The creature can use its action to attempt another Strength (Athletics) check to escape.

Crossing the Void

If a creature passes through the wall, it must make a Constitution saving throw. On a failed save:

• It takes 6d8 necrotic damage immediately 

• It is Frightened of the wall until the end of its next turn.

Horror of the Infinite

The writhing hands whisper with voices from the void. The first time a creature comes within 10 feet of the dangerous side, it must succeed on a Wisdom saving throw or become Frightened of the wall until the end of its next turn.

Flavor

The wall appears as a tear in reality, an endless black gulf where thousands of pale hands claw desperately toward the living.

Using a Higher-Level Spell Slot. The damage increases by 1d8 for each spell slot level above 5.
