Corridor of Whirring Bones

Read Aloud

The floor panels snap open, and three brass skeletons rise through the gears with steam boiling from their joints. Walkways slide sideways beneath your feet as the guardians turn in perfect unison toward the shard. A violet-lit door waits at the far end of the corridor.

Battlefield Zones

1
Gear Floor

Gears fill the floor; creatures ending their turn beside a moving gear make a DC 14 Dexterity save or take 1d6 bludgeoning damage and move 5 feet.

2
Sliding Walkways

Two metal walkways slide sideways each round; entering or ending a turn here requires a DC 15 Acrobatics check or the creature falls prone and slides 10 feet toward the guardians.

3
Console Bend

Flickering consoles line the walls beneath violet emergency lights; each console can issue the halt command.

Terrain Levers

  • Disable a steam vent with a DC 15 Intelligence (Arcana) or Investigation check as an Action; the next vent cycle skips that vent.
  • Broadcast a halt command from a maintenance console: Action, DC 15 Arcana or Investigation; each guardian within 30 feet makes a saving throw against the check result or is stunned until the end of its next turn.
  • A creature can jam a moving walkway with an Action and a DC 16 Strength check; the walkway stops until the end of the next round.
  • Thunder damage against a guardian exploits its vulnerability.
