Cadaver Collector Monster Guide for D&D 5th Edition

The ancient war machines known as cadaver collectors lumber aimlessly across the blasted plains of Acheron until they are called upon by a necromancer to bolster the ranks of a conquering army on the Material Plane. These fearsome Constructs obey their summoners until they are dismissed back to Acheron, but if a summoner comes to a bad end, a cadaver collector might wander the Material Plane for centuries, collecting corpses while searching for a way to return home.

Each creature in that area must make a successful DC 18 Constitution saving throw or be paralyzed for 1 minute. A paralyzed creature repeats the saving throw at the end of each of its turns, ending the effect on itself with a success.
