It is the same thing as a Lizard Jerkin, except it's the HQ version, which gives +1 def.
Also, there's no way to get one unless you have Leathercrafting high enough or are lucky enough to HQ it while skilling up. It's easy to HQ these if you are level 50+ Leathercraft. I usually get 8/10 HQ, or so.
The recipe I believe is.. Earth Crystal: 3 Lizard Skins, 1 Sheep Leather.
I despise harnesses and subligars. ^^ exception only to SH.
This is, essentially, the Lizard Jerkin +1. It's crafted in the exact same way that the Lizard Jerkin is, and you only get this result on an exceptional crafting.
I wear this armor, and while I do absolutely hate how it looks, I have noticed a DEFINITE differances in mod hit ratio and damage against me. For it's level, it's one of the best Red Mage armors I've found.
You can buy them at the AH, you can get skill in Clothcrafting and make your own, or you can get some one with a high skill in Clothcrafting to make it for you. Your best bet is to buy it because the materels may cost more and to make something "fine" it takes alot of skill. At this lvl I got the normal Lizard set of armor.
