Recall Knowledge DC 31 (arcana)
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.

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.
