How to Get It: It is actually a leatherworking item that requires a high-level tailoring item to make (so your guild would usually have a high-level leatherworker assigned to put cloaks together for them, as well as a tailor to make the Cindercloth Cloaks required). Along with a few vendor items to get
cheap wow gold, it also requires a Scale of Onyxia, which dropped at 100% rate once every Onyxia kill. So basically, if you wanted to outfit your 40-man (yes, 40) raid with a cloak each, you would have to down Ony 40 times to make everyone a cloak about
cheap wow gold.
And to get the pattern in the first place, you have to down Onyxia, take the head to a faction leader, and then they will send you to a quest giver that will teach you the recipe for the cloak. Feeling nostalgic yet, old-school raiders?
Keep in mind that if you are 70, you will not see the exclamation point to find this quest. You will have to turn on low-level quest tracking if you want to see it. And you will probably have to do it before patch 3.2.2 to get
cheap wow gold since the old Onyxia is likely going bye-bye.
You never know when Nefarian might return -- maybe for the 10th anniversary? But in case you are not worried about that, you can trade the cloak in for 1g 51s 98c, disenchant it into a Large Brilliant Shard about
cheap wow gold, or sell it on the AH, as it is BoE.
If you do not have classes with low-cool down interrupts in the party, you will have to save one for Blizzard or, for safety sake, refrain from killing the Fire and Arcane copies until after the Frost copy finishes channeling.
