  • Antimagic Susceptibility. The clockwork is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the clockwork must succeed on a Constitution saving throw against the caster’s spell save DC or fall unconscious for 1 minute.
  • Constructed Nature. A clockwork creature doesn’t require air, food, drink, or sleep.
  • False Appearance. While the audience remain motionless, they are indistinguishable from mannequins.
  • Repairable. A DC 10 tinker’s tools check restores one hit point for each point rolled over the DC.
  • Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a Small humanoid. The swarm can’t regain hit points or gain temporary hit points.
  • Vril Engine. When the construct dies, it inflicts 20 (6d6) force damage in a 10 ft. radius. Creatures in the radius can make a DC 12 Dexterity saving throw for half damage. Alternately, when it suffers a critical hit or dies, roll on the Clockwork Engine Malfunction table.


  • Multiattack. The swarm makes one Clockwork Mass attack and one Grasping Limbs attack.
  • Clockwork Mass. Melee Weapon Attack: +5 to hit, reach 0 ft., one target in the swarm’s space. Hit: 6 (1d6 + 3) bludgeoning damage, or 5 (1d4 + 3) bludgeoning damage if the swarm has half of its hit points or fewer.
  • Grasping Limbs. Melee Weapon Attack: +5 to hit, reach 0 ft., one creature in the swarm’s space. Hit: 7 (2d6) bludgeoning damage, and the creature must succeed on a DC 13 Strength saving throw or be restrained. The creature can repeat the saving throw at the end of each of its turns, taking 7 (2d6) bludgeoning damage on a failed save. The creature is freed if it succeeds on this saving throw, the swarm moves out of the creature’s space, or the swarm dies.


This cobbled together mannequin is made of different types of metal.

Mannequins are the animated scraps of other projects. Turned into cheap labor through the power of vrilgonite, they fill a wide variety of roles ranging from pilot to chef, personal assistant to audience member.

Most vrilwork mannequins encountered individually are typically provided low-powered vril staves and given roles of important responsibility like pilots, guards, etc.

Gnomish audiences are filled with sunwork eyes and a cluster of vrilwork mannequins known as an audience. The mannequins are dangerous separately, but they are deadliest in groups, where they become a flailing swarm that can overcome any foe.
