Wailing Crystals

COMPLEX HAZARD 13
Stealth +27 (master) or DC 37 Perception (master) to notice what appear to be screaming ghostly faces in the crystals
Description Three clusters of gleaming, colorful crystals are corrupted with necromantic energy that causes them to reflect negative emotions. All three must be disabled or destroyed to negate the hazard.

Disable DC 29 Thievery (master) to carefully fracture the crystals or DC 27 Crafting (expert) to place objects to stop the resonance, both disabling one 5-foot patch of crystals.

AC 34; Fort +26, Ref +18
Hardness 18, HP 72 (BT 36); Immunities critical hits, precision

HP is 72 for each 5 foot patch
Echoing Cry (occult)
Trigger A living creature approaches within 20 feet of a wailing crystal.

Effect A despairing chorus of cries echoes off the crystals, working its way into the minds of all living creatures in Jewelgate Way Station, affecting them with Wave of Despair (7th level, DC 33 Will save).

The hazard rolls initiative.

Anguished Shriek (emotion, mental, occult, sonic)

A shrieking, distorted face composed of writhing necromantic energy lances out of the crystals to target a random living creature within 20 feet. The target takes 4d6 mental damage and 4d6 sonic damage (DC 33 basic Will save).

Routine (3 actions) The hazard uses each action for an Anguished Shriek. The wailing crystals lose 1 action for each 5-foot patch of crystals that is broken or destroyed.
Reset The wailing crystals deactivate and reset once no living creatures are within 20 feet.
