You forge a bond between a creature within 30 feet from you that you can see, and the writhing depths of the maddening unknown.

When you cast this spell, the target must make a Constitution saving throw. The target takes 12d8 acid damage on a failed save, or half as much damage on a successful one, as a torrent of worms spews from their mouth. If the target fails its saving throw, it is incapacitated until the end of its next turn.
