Crushing Gravity Well - AI-generated fantasy Hazard

Crushing Gravity Well

An invisible pocket of unstable arcane density centered on a specific floor tile. When weight is applied to the focal point, the gravity within a 15 foot radius increases by a factor of fifty, instantly dragging everything toward the floor with bone shattering force.

Detection

PerDC 18 (To notice light lensing or dust behavior)
StlDC 18 (Visual distortion and sound dampening)
InitN/A (Simple Hazard)

The air in the center of the room appears to shimmer like heat haze. Upon closer inspection, the stone floor tiles directly beneath the shimmer are hair-line fractured and slightly concave. Dust motes that drift into the area seem to drop suddenly as if struck by an invisible hammer.

Standard Engagement

Trigger

The trap is triggered when a Medium or larger creature steps on the central tile or when more than 100 pounds of weight is placed on it.

Routine

None. The effect occurs immediately upon trigger.

Reset

The gravity well remains active for 1 minute after being triggered, then resets to its dormant state.

Gravitational Collapse

Each creature within a 15 foot radius of the center must make a DC 19 Strength saving throw. On a failure, a creature takes 55 (10d10) force damage, is knocked prone, and is restrained until the start of its next turn. On a success, the creature takes half damage and is not prone or restrained.

Density Increase

While the hazard is active (1 minute), the area within 15 feet is considered difficult terrain. Ranged weapon attacks that pass through this area automatically fail as projectiles are pulled to the floor.

Atmospheric Void

While the well is active, sound cannot pass through the area. Creatures inside are deafened and cannot cast spells with verbal components.

Description

An invisible pocket of unstable arcane density centered on a specific floor tile. When weight is applied to the focal point, the gravity within a 15 foot radius increases by a factor of fifty, instantly dragging everything toward the floor with bone shattering force.

Discovery

A character who succeeds on a DC 18 Intelligence (Arcana) or Wisdom (Perception) check notices the subtle bending of light (gravitational lensing) around the trigger point. A character with the Detect Magic spell perceives a dense, pulsing orb of Transmutation magic embedded in the floor.

Archival Lore

Created by the high mages of a fallen empire to guard their most sacred reliquaries, these wells utilize a piece of a collapsed star or 'void-glass' to tether local physics to a singular point of failure.
