  • 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.
  • Bounce. When a bouncesphere strikes a target who is wielding a shield or a melee weapon, they can potentially bounce the bouncesphere off of it in another direction as an action on its turn or as a reaction to another creature using its action to bounce it. The target must make a DC 13 Dexterity saving throw (at disadvantage if the weapon inflicts slashing or piercing damage). On a success, the target can choose another creature or object it can see within 30 feet of it. The bouncesphere targets the chosen creature or object instead of the target and the attack roll is rerolled against it.
  • Constructed Nature. A clockwork creature doesn’t require air, food, drink, or sleep.
  • Magic Resistance. The bouncesphere has advantage on saving throws against spells and other magical effects.
  • Repairable. A DC 10 tinker’s tools check restores one hit point for each point rolled over the DC.
  • Siege Monster. The bouncesphere deals double damage to objects and structures.
  • Vril Engine. When the construct dies, it inflicts 3 (1d6) force damage in a 5 ft. radius. Creatures in the radius can make a DC 13 Dexterity saving throw for half damage. Alternately, when it suffers a critical hit or dies, roll on the Vril Engine Malfunction table.


  • Multiattack. The bouncesphere make two slam attacks.
  • Slam. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 +3) bludgeoning damage.


This ball-shaped clockwork shoots jets of air out of apertures on six of its sides.

Bouncespheres are jet-propelled weapons with a mind of their own. They bounce back and forth, striking objects or creatures within range. The bouncsphere bounces from one target to another, although savvy creatures can attempt to smash it back at opponents.

Bouncespheres are most often found in places where there are plenty of obstacles to bounce off of: forests, pillars, or ruined cities.
