I am seeing more of these on sale at low prices. Doubtless picked up by players unsuspecting of their value and put on the Auction House.
These allow a Jewelcrafter, after a simple repair, to claim one Dalaran Jewelcrafter’s Token which goes towards buying Wraith of the Lich King Jewelcrafting recipes off the vendor.
There are two other ways to collect these tokens: one is to do a daily quest which is the norm - takes 5 minutes assuming you start of Dalaran (big ask); the other is to trade in 10 titanium dust which is hideously expensive.
On my server, Jewelcrafters are willing to pay up to 500 gold for these Damaged Necklace’s – so picking them up for less than 100 gold to flip is a sure fire winner.
They should be on everyones Snatch Lists.
