Scaling the Chain

COMPLEX HAZARD 0
Stealth +14 (trained)
Description The PCs appear on a gigantic wall of hooked chains dangling in a gray swirling mist. The chains radiate life-chilling energy Cries of innocence and condemnation echo through the mist in Elven. A plane of light 10 feet above eddies and swirls as it dully reflects the PCs below, but the reflections warp and alter the PCs to have sallow complexions like the undead.

Disable A PC that has ascended to the plane of light (DC 13 Athletics check to Climb; on a critical failure, the PC falls 10 feet before being seized by a chain) can attempt a DC 18 Thievery check to disrupt the plane or a DC 18 Arcana, DC 18 Occultism or DC 18 Religion check to ritually disrupt the haunting. Each success reduces the haunt's actions by one. When the haunt has no more actions, it is disabled and the PCs all return to area B3.


The Pain of Devotion (unholy)
Trigger Hunted by Chains is disabled

Effect The chains rattle ominously, dealing 1d6+2 void damage to all creatures in the haunt (DC 16 basic Will save). The haunt then rolls initiative.
Routine (three actions) The chains rattle and sigh ominously around two different random creatures trapped in the haunt, dealing 1d6+2 void damage (DC 16 basic Will save).
Reset The haunt resets the next time the Soulshackle traps creatures in the library.
