Detection

PerDC 18 (Launcher Slits)
StlDC 18 (Launcher Slits)
Init14

Dark stone walls with narrow vertical slits every few feet. The opposite wall is marred by deep, star-shaped impact gouges and dried brownish stains.

Standard Engagement

Trigger

A creature steps on a hidden pressure plate or fails the puzzle lock governing the corridor entrance.

Routine

On its initiative, the trap fires 1d4 additional chains if it has remaining ammunition (12 chains total). Each chain targets a random creature in a 10-foot section of the corridor. Target: +7 to hit, 2d10 piercing damage and the target is Restrained (escape DC 14). While Restrained, the creature takes bleed damage.

Reset

The trap must be manually rewound using a heavy iron crank, requiring 1 hour of labor.

Severing Strike

A barbed piton slams into the target. On a hit, the creature takes 2d10 piercing damage and is Restrained (DC 14 Athletics or Acrobatics to escape).

Infernal Bleeding

A creature that takes damage from the chains begins to bleed out. It takes 1d6 necrotic damage at the start of each of its turns until it receives magical healing or a creature uses an action to make a DC 12 Wisdom (Medicine) check to bind the wounds.

Razor Wire Web

The corridor is filled with taut chains. It is Difficult Terrain. A creature that moves more than 5 feet through the web must succeed on a DC 13 Dexterity (Acrobatics) check or take 1d6 slashing damage.

Description

Hidden launchers within the walls fire high-tension barbed chains that stretch across the room, creating a lethal web of razor wire designed to flay flesh and ensnare intruders.

Discovery

A DC 18 Wisdom (Perception) check reveals the concealed slits. A DC 16 Intelligence (Investigation) check identifies the pressure plates or the faulty mechanism in the nearby puzzle door.

Archival Lore

Engineered by the smiths of Minauros, these traps are used to secure the Cages of Perpetual Sorrow and high-security vaults of the Nine Hells.
