Warden jack swarms have two modes of attack: as moving caltrops, or as rolling marbles. They set themselves up for combat by rolling into the path of their opponents and extending their spikes.

During Combat Once combat begins, most of them roll around continually, extending their spikes and attempting to wound an opponent. Some remain in spheroid form in order to get under the feet of a foe and bring it to the ground. Extending or retracting spikes is a free action for the warden jack swarm.

Warden jacks are miniscule metal objects in the shape of a ball covered in sharp spikes. These things are able to move on their own by retracting their spikes, and rolling along the ground. They are commonly used as guardians by wizards and nobles who fear the intrusion of thieves. Warden jacks never attack their creator and can be programmed to avoid specific individuals or types of individuals, or to attack only specific types of individuals, or attack only under specific conditions as specified by the creator.

These constructs are capable of guarding an entire floor or area, but are unable to climb up stairs and are stopped by closed doors or other impassable objects that they cannot fit through. They can, however, fall down stairs or navigate even the steepest of slopes.

Warden jacks resemble caltrops somewhat, and typically range from 1-3 inches in diameter.
