  • Integrated Shield. The clockwork guardian has an integrated shield welded into its hands, making it impossible to disarm or destroy.
  • Winding. A clockwork guardian can function for one week every time it is wound. A creature of at least Small size can use an action to wind the clockwork guardian, restoring it to one week of operating time; a creature of Tiny size can wind it at half this speed.


  • Multiattack. The clockwork guardian makes two shield bash attacks.
  • Shield Bash. Melee Weapon Attack: +8 to hit, 5 ft. reach, one target. Hit: 16 (2d10 + 5) bludgeoning damage.


  • Barrier. The clockwork guardian chooses three squares adjacent to it to represent which side of the body its shield is on. These squares remain the same until the clockwork guardian uses a bonus action to change which side the shield is facing. If a creature makes a melee weapon attack against the clockwork guardian from one of those squares, the attack has disadvantage. Similarly, if a creature makes a ranged weapon attack against the clockwork guardian that passes through one of those squares, the attack has disadvantage.


Clockwork guardians are dedicated to the art of defense. They work best when they operate in small groups, under orders to defend specific locations from intruders. Their standard operating procedure is to force foes out of their respective holdings by use of overwhelming force. A clockwork guardian is 7 feet tall and weighs 750 pounds.
