Description

The rarest manifestation of brazen spheres is the Brazen Sphere Imprisoner, a form that only emerges in response to a solitary intruder. Standing at 8 feet tall, this sphere envelops the targeted intruder upon activation. Once initiated, all spheres within the vicinity roll toward the intruder at a speed of 60 feet per round, merging into the larger spherical form. The intruder can evade this enclosure by making a saving throw. Failure results in the spheres creating a metallic cage around the victim, rendering them immobile. The brazen sphere imprisoner then enters a dormant state, detaining the victim until either the imprisoner is subjected to an attack or the correct command word is given to deactivate the construct.

Regrettably, most victims succumb to starvation or thirst, as those with knowledge of the command words for release are typically long-deceased.

Brazen Spheres

Crafted in ages past in the legendary city of brass, these inch diameter brass spheres boast a smooth exterior engraved with intricate runes. Brazen spheres typically lie dormant in substantial numbers within treasure vaults, ancient tombs, and temples, serving as guardians for precious artifacts. Often concealed, they can seamlessly blend with the treasures they protect. However, upon the attempted removal of the safeguarded treasure, the spheres activate. The etched runes softly glow in various colors, pulsating at varying rates.

Over the course of one round, the brazen spheres roll together, merging into one of the four constructs detailed below. This construct immediately launches an attack, catching opponents by surprise on a roll of 1-4 on a six-sided die, unless they have witnessed this behavior before.

Once the spheres have coalesced into one of the constructs, they appear bonded, moving independently while remaining part of the larger entity. Their fluid movement, akin to water flowing as they move around one another, enables the constructs to traverse obstacles or move through small gaps effortlessly, as if they weren't present. This fluidity also grants the construct immunity to physical missile weapons, as they are able to simply flow around the projectiles. Additionally, brazen spheres are impervious to natural fire-based and only take half damage from magical fire, such as a fireball. Individually, brass spheres can move up to 60 feet per round.

Upon defeating a construct, the spheres comprising it lose their cohesion and collapse to the floor as individual objects. If left undisturbed for a year and a day, they reset, ready to rejoin as a construct when triggered once more. However if the dormant spheres are broken open, each contains a sapphire chip; each 1 HD of spheres that made up a construct will have 100 gp worth of sapphires.
