Corrupted Hellborn Grasp

From the description

A week of incantations were spent to pierce beyond the mortal realm and consort with what lay beyond. Finally, a sliver of infernal light appeared and from depths unknown rumbled a distant wail of suffering and anger. The wretched sound grew and grew into a deafening roar before a hellborn claw reached through the burning tear into the world. Yet in its unseeing fury the invading appendage disrupted the ritual, and the vile mouth from whence it sprang suddenly closed shut, forever severing the vile hand from its unknowable owner.
