Recall Knowledge DC 26 (arcana)
Disable DC 28 thievery (expert) or DC 28 crafting(expert) to find the weak spot and crack each facet, or dispel magic (5th level; counteract DC 26) to counteract each facet; the hazard has a number of facets equal to the number of PCs.
Spectral hag claws reach out from the walls of the gem-like chamber to grab the PCs' souls and pull them into the trap's onyx facets.
