  • Multiattack. The acronical makes two hook attacks.
  • Hook. Melee Weapon Attack: +6 to hit, reach 10 ft., one creature. Hit: 13 (2d8 + 4) slashing damage.
  • Drain. Melee Weapon Attack: +6 to hit, reach 10 ft., one creature. Hit: 11 (2d6 + 4) slashing damage plus plus 7 (2d6) poison damage. If the target is a creature other than an undead or a construct, it must succeed on a DC 13 Constitution saving throw or lose 5 (1dl0) hit points at the start of each of its turns. Each time the acronical hits the wounded target with this attack, the damage dealt by the wound increases by 5 (1d10). Any creature can take an action to stanch the wound with a successful DC 12 Wisdom (Medicine) check. The wound also closes if the target receives magical healing.
  • Invisible Passage. The acronical magically turns invisible until it attacks, or until it’s concentration ends (as if concentrating on a spell). While invisible, it leaves no physical evidence of passage, so it can be tracked only by magic. Any equipment it wears or carries is invisible also.


The acronical is a large insectile predator that strides on six armored legs. Eight feet tall at the shoulder, it has a dark maroon exoskeleton and serrated black hooks at the end of both arms. It reeks of vomit.

Created by priests many centuries ago, this nocturnal creature stalks and kills adulterers. It hunts married people who stray from their spouses, and those who tempt or dally with married people.

Acronicals are drawn to the scent of such persons, and can detect it from miles away. The beasts crawl across walls and ceilings, silent and careful, closing in on their victims. They stalk everyone who was peripherally involved in the duplicity, neighbors who turn a blind eye, innkeepers who knew exactly what was going on, and so forth. Those involved are tracked down, attacked while alone, hamstrung, and devoured by the acronicals while still alive.
