Net Cannon (4/Day)

Ranged Weapon Attack: +3 to hit, range 10/20 ft., one target. Hit: If the target is a Large or smaller creature, it is restrained. A mechanism within the clockwork watchman's chest can fire a net with a 20-foot trailing cable anchored within the watchman's chest. A creature, including the restrained creature, can take its action to free the restrained creature by succeeding on a DC 10 Strength check. Alternatively, dealing 5 slashing damage to the net (AC 10) frees the creature.
