Just a headsup, this might already be news to many already, but there's a savage blood dupe going around. Players claiming to sell 60-100x in trade at 1k apiece with gibberish names, and they're also on the AH too, usually from real players buying and relisting trying to flip, ala Queens Garnet. You can look up many of the high pops and see the spike on December 19th, so it's only been live for a couple of days or so.

Also remember that we don't discuss duping methods on MMO-C, but it's similar to the ones we've seen in the past xpac. Same deal.
So yeah, don't invest too heavily in these. Prices will keep dropping as dupes continue to bottom them out. Might be 500g soon. Hope this saves someone a big chunk of gold! On the bright side 665 boes will be coming down in price, as they weren't really worthwhile at 15x Savage Blood and 150x daily cd items.
