Hunted by Duty's Bonds

COMPLEX HAZARD 1
Stealth +13 (trained)
Description Shadowy chains reach out to ensnare creatures trapped in the mindscape.

Disable DC 18 Acrobatics to avoid the chains, or DC 18 Arcana, DC 18 Occultism, or DC 18 Religion 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 Scaling the Chain haunt triggers.


Chains of Undeath (mental)
Trigger Talhindir's Autumn is disabled

Effect A spectral image of Duty's Soulshackle appears in a display nook, snaking out chains of dark energy toward each creature. Each living creature in the haunt must attempt a DC 16 Will save or be Frightened 1 The haunt then rolls initiative.
Routine (two actions) Spectral chains snake out to wrap around three different random creatures trapped in the haunt, who must each succeed at a DC 17 Reflex save or have the Restrained condition until it Escapes. Each round that a creature starts its turn Grabbed, it takes 2d4+1 nonlethal force damage. Spectral scars form on any creature knocked Unconscious by this haunt.
Reset The haunt resets the next time the Soulshackle traps creatures in the library.
