Locus of Pain

COMPLEX HAZARD 12
Stealth +27 (expert)
Description An arcane orb sits upon a sinister altar, filling creatures in the area with unimaginable pain.

Disable DC 27 Medicine (master) to soothe the locus's pain, DC 30 Occultism or DC 30 Religion to counteract the locus's energies, DC 35 Thievery (master) to extricate the orb from the altar

AC 30; Fort +25, Ref +19
Hardness 20, HP 82 (BT 41); Immunities critical hits, precision

Agony Lash (emotion, mental)
Trigger A creature touches the orb or attempts to disable the haunt

Effect All living creatures within 60 feet are overwhelmed by pain and must succeed at a DC 32 Fortitude save or be Sickened 1 (Sickened 2 on a critical failure). The haunt then rolls initiative.
Pain Manifest

Casting Calm or Soothe in the orb's presence automatically destroys the locus; other spells or abilities that ease pain might also do so, at GM discretion.

Unholy Repair

The locus is sustained by the power of Tar-Baphon. The orb regains 10 Hit Points at the beginning of every round and is repaired by void damage.

Routine (1 action; mental, nonlethal) Creatures affected by the haunt's agony lash are wracked with pain, as 4th-rank Phantom Pain (DC 32 Will). If a creature falls Unconscious due to the haunt, they don't continue taking damage.
Reset The haunt deactivates 1 minute after all living creatures leave the area. After 1 hour, the haunt reactivates.
