The 480 ilvl necklaces in this dungeon are capable of being disenchanted into Sha Crystals. Anyone know if this is intentional or not? I'm assuming it isn't since the Halloween rings weren't and a group of five can farm one Sha Crystal in about 2 minutes. Anyways, happy farming!
It's intentional as all previous CCC items where disenchantable, it's just that this event now comes in a time in the expansion where the epic crystals are still not that common due to lack of epic drops in 5 mans.
Enjoy it and enjoy the price crash for cheaper enchants.
