Total Materials Requires to complete this quest:

40 Scorpid Scales
36 Thick Leather
12 Silken Thread
10 Worn Dragonscale

Best Places to farm for the Materials:

Scorpid Scales - Tanaris. There are Scorpids everywhere. The closer to Gadgetzan, the lower level they are. However, this could be more dangerous if you're on a pvp server. If you want to play it safe, you may want to ride further south away from town towards some of the higher level scorpid spawn.

Worn Dragonscale - There are three great locations to farm for these, with the Dragon population levels being 41-43 on average.

• Swamp of Sorrows - The Green Dragonkin that surround the Sunken Temple
• Dustwallow Marsh - The Red Dragonkin that inhabit the southern part of the map; Wyrmbog, Stonemaul Ruins, and Onyxia's Lair
• Badlands - Lethlor Ravine, which lies at the eastern most end of the map, is infested with Scalding Whelps

Of course, mail armor falls under the Dragonscale area (duh!) - primarily for Hunters.&nbsp Elemental has some good stuff but is primarily focused on rogue benefits.&nbsp Tribal also has some good stuff for rogues but primarily benefits the druids.&nbsp Of course, all leatherworkers can make the Scorpid (mail) armor - the majority of LW items remain open for all.&nbsp The really good items for all LW require Friendly, Honored or Revered with some faction (Timbermaw, Zandalar, Argent Dawn or Cenarion Circle).&nbsp So, the question is:&nbsp do you want to make items to sell or items for personal benefit?&nbsp I would guess that rogues provide the largest specialized market (Elemental) and hunters the second but farming for materials increases the difficulty of the DS area (none are easy materials to get).

I hit 250 in LW at Lv 45 and went Tribal (Alliance � NE Druid).&nbsp If you need anything on Detheroc, let me know.

BTW - from what I understand, I don't believe it is possible to drop one of the specialization areas to take up another.&nbsp You could drop leatherworking as a skill and start all over again after adding it as a new skill.&nbsp But then, you can't do the Wild Leather quests again in order to take up one of the specialization areas.&nbsp It would appear that it cannot be done.

This quest is very easy for a level 42 to get to. My Dwarf Hunter who is level 42 just ran by on my mount and had no trouble until I met a naga who knocked me off, then I just used Fiegn Death and they ran away, then I continued on after I got on my mount. After I got the quest all I did was go to Ironforge and log off. Easy as that. If your level 47-48 you should have no problems getting there, even if you do stop to fight the monsters. And my route was follow the road until you get to the second right turn and there were a few naga there, and that one deer that doesn't attack you whose right outside of the camp he's in, and then I got the quest. It's right outside the Forlorn Ridge or something like that.

Good luck if your trying to get to him!

This in my opinion is the best Leatherworking path for Hunter Leatherworkers. This is the dependency that a lot of the Mail items in Leatherworking requires. The quests to get Dragonscale Leatherworking are hard but well worth it. Peter Gralen is located in Azshara and will start you with the first quests to obtain Dragonscale LW.

A good place to farm Dragonscales are in the Badlands, by where all the dragons patrol. I think it's the fastest way to get them besides having to buy them in the Auction House.

Your Dragonscale Leatherworking trainer is Peter Galen in Azshara. (been there thinking it was for me.... x_x )

This quest is only available if you have also reached LW 225.

Follow the road east from Astraanar and ,without deviating from the path ,you will zone into Azshara. Staying the path you will come to some ruins that some mid-40 Naga inhabit. Take a right through these ruins avoiding all the Naga you can and ,hopefully, outrunning the rest on your mount you will come to the small camp where Peter is hanging out. To make this trip a one time thing be sure you have all the necessary items in addition to having LW up to 255.

It isn't difficult to get to Peter without being hit once. Anyways, hope that helps^^

Another good place to obtain worn dragonscale if you are level 49 or above is around Onyxia's Lair in Dustswallow Marsh. You can circle her lair, clearing out dragonkin as you go, and harvest a ton of thick leather, heavy leather, and of course worn dragonscale.
