If you're a horde warlock and working on this, pickup Befouled by Satyr https://classicdb.ch/?quest=1434 also from the NPC at the kodo graveyard camp. The mobs killed in that quest are the same ones that drop the Hatefury blood. Also, the drop rate isn't great but it isn't bad either.

I was able to solo this entire quest chain at level 31 and get the robe. Although there are better robes to get in your 30s, I'm pretty sure this is the best robe locks can get at my nub level. The most difficult parts are, by far, the infernal stone and the smoldering coals, respectively (infernals are way more difficult than the elementals, surprisingly), so I'll just go over those.

Both of the areas you have to go to for these components are high traffic, high pvp zones, and you're liable to get ganked just for being there, so if you're on a pvp server, I'd highly recommend hiding behind a corner and busting out your eye to scout before proceeding, because you're going to be there for a few minutes. As it turned out, there were some allies out in Arathi farming my mobs and the eye kept me from wandering into trouble.

OK, so first the hard part- the infernal. How do you solo a mob 6-7 levels up? Very carefully and slowly. I used my infernal for this and dropped some +health regen pots to help out, although the pots may not have been neccessary. The trick here is to make sure your v-dub keeps agro by taking one of his taunts off autocast and hitting it whenever neccessary to pull agro off yourself. If you play a warrior (60 warrior, here), then hopefully you know that your taunt ability doesn't actually add to agro, it merely puts you on the top of the agro list. It's an agro "puller," but not an agro "keeper." I don't know the details of vdub taunt, but I assumed it worked the same way as the warrior taunt.

Wait a few seconds for vdub to get a firm hold on the mob, and let loose your dots. I'm affliction spec, so I have three insta-dots, and I just used those. I seem to remember infernals being resistant to fire damage (but don't quote me on that!), and didn't bother with any fire spells. I just cast the dots until they landed, waited a second, then drain life'd as neccessary so I could heal v-dub when he needed it. This is not a race- if you do too much damage, you'll pull agro and die very quickly. I didn't use a single nuke, and I think I might've died if I did. If things start getting hairy, sac v-dub, aplify curse + CoEx, pray it lands, and run. Stone dropped off the first infernal I killed.

And now the easy part- the elementals in arathi for smoldering coals. Just buy a stack of cresting charms at the AH (I bought 10 for a G), and use those. Drop rate was not 100%, more like 50, and I had six charms left over.

As a side note, warriors use those charms for their whirlwind weapon quest, and you could probably make a fellow nub guildie warrior happy by saving them for him/her. Farming for those really sucks, especially if you're trying to get your weapon at the earliest level possible, and the help is usually appreciated.
