Tendrils of darkness flow from the ground like smoke, filling the area with writhing, shifting darkness. A cold draft washes over your soul even as the tendrils rise.

The area of deadly shade is filled with shadowy illumination, as per darkness. In addition, each time you invoke this mystery, decide if you wish the spell to deal or absorb damage.

An oily black smoke rolls out of nowhere, obscuring sight and sound. It leaves a distasteful residue on everything within, and the scent is one of open sewers and putrefied flesh.

Plumes of blackness swiftly fill the air like a viscous fog. The shifting of shadow and mists just barely suggests the presence of screaming faces and indescribable horrors lurking in the dark.
