I have been stalled with LW since I hit 355, I'm sure the rest of you know this particular spot. It's when the green mail recipes dry up and we're forced to make blue stuff. Well I just haven't had the time to farm copious amounts of leather and primals with all the other things I've been doing, so Kali just sat at 355 for weeks.
The other day I finally decided to suck it up and find a place to get my specialty leathers so I could start crafting again. I had been buying cheap Primal Shadows off the auction for under a gold each. I was hoping if I farmed all my own leather I could keep my investment minimal on the blue items. I had zeroed in on the Fel Leather Gloves as the best use of cheap primals and leather. The recipe is yellow to me @ 355 but I thought it was worth the risk.
I tried several locations for farming the Fel Hides required to make this item, but I kept having terrible luck. I would spend an hour on one mob type and end up with maybe a handful of hides. Clearly this wasn't going to cut it. So I went back to Allakhazam (again) to find a new spot to try and saw a post by another player saying that the Arklon Ruins were a good place to farm Fel Hides. Turns out he was spot-on with that assessment! This is the best farming I think I've done anywhere, including my Thick Clefthoof Leather farming spot.
The demon hounds that hang out in Arklon are very easy to drop. I was only having to HoT myself every 4-5 kills. By comparison I usually have to heal every 2-3 kills farming the 67-68 mobs near Cosmowrench. These little guys just don't hit hard and they drop fast, they have about 5k hitpoints. They're also like the perfect Fel Leather farming beast. They drop everything you need to make Fel Leather gear: motes of shadow as loot + knothide/fel hides from skinning. I was able to get at least a dozen hides in about an hour, plus a couple of knothide stacks. It's like a one-stop shopping bonanza!
The best part is that they also drop decent loot, not the usual vendor trash you find on beasts. If you are Aldor they are perfect for faction farming, I was getting about 40 Marks of Sargeras in 90 minutes of farming. Now I'm Scryer, so that wasn't particularly beneficial to me. But hey, I just plopped those on the AH and bought the equivalent Scryer drops instead. I went from 8k to 12k and dinged Revered with Scryer by doing this. Not bad for a couple of days work, plus enough leather mats to get 5 skill points to boot. I'll take it!!
**2.1 Update** Motes of Shadow have been removed from demons, now they are only found on "voids". I haven't personally confirmed this, but I assume the motes will no longer drop from these demon hounds.
