The Sinner Sentry is bound high above, dementedly keeping watch for sinners.
Its core is usually comprised of signal lights, alarms, sirens, or signs that serve to "guide, signal, or warn." From its core, pale tendrils twist and tangle to roughly form a humanoid shape.
These Biomechanicals are coated with a thick, tar-like substance that quickly corrodes and decays anything they touch. As a result, the facilities they cling to are usually in a state of severe disrepair. However, those facilities continue to function normally, regardless of whether they are powered or not.
The Sinner Sentry typically appears at high, prominent positions on artificial structures. If someone within its line of sight violates the "rules" its core (located in its head) represents - such as ignoring traffic signals, speeding, or crossing forbidden areas - it immediately breaks free and attempts to eliminate the target.
Once freed, the Sinner Sentry uses Stardust energy to fly through the air. It can energize loose Stardust and shape it into simple destructive effects, typically a crackling ray or a sticky splatter of gel. When a creature is hit, the affected area rapidly oxidizes, drying out and corroding until it becomes charred, much like being burned by acid.
