Strained Supplies

This quest is only available to characters hostile to The Aldor. It is repeatable and used to switch over from The Scryers.

Aight, so these things drop off Dreadfang Lurkers and Widows and with an estimated (quite correct) drop rate of 34%. You turn these in, 8 by 8 to get 250 reputation per turn-in with the Aldor if you chose the Scryers by mistake, want to change for a pattern, going for the Feat of Strength achievement Hero of Shattrath or whatever reason you want to come up with.

Strained Supplies is the way to turn in this things, although you don't need the quest to loot them! Correct, you can farm these without the quest which you might also want, because the achievement will require you (from 0/36000 Hated) to turn in, not one, not two, but 1344 of these beauties (Warning: This is a calculation based on the non-Human races, for a Human, that would be 1224). Oh yes, that many. It takes you to Neutral, making you able to do quests for the Aldor, as well as other turn-in quests.

So how am I gonna get 1344 before I die, you ask? Well, here's the answer, aswell as a good route starting just outside the Alliance camp Allerian Stronghold (which is also a very good place to clear your bags in a way earning your money, unless you use addons like Loot Filter). So running back and forth between Allerian Stronghold and Netherweb Ridge south of it at the edge of Outland might not be so fun you think, but with the right resolve and some good music you can earn above 100 per hour. I succeeded in getting exacly 100 per hour a couple of times, so with some complex maths it's about a 13-14 hour farm.

I noticed that instead of pressing "B" every few seconds to see how many you've got left to gather, you can fix a macro. Because the game won't let you drag non-usable items out on the bars, you can always make something simple, such as;

#showtooltip Dreadfang Venom Sac

Works really smooth. The icon shows how many you've got, and if you hold your mouse over it, it shows how much gold you're wasting not selling them to a vendor! (Combine this with an addon such as BankItems and you'll even see how many your account has, it you can't be arsed filling your farmer char's bags with them!)

So there you go, a small guide for farming the Feat of Strength achievement Hero of Shattrath!

Good luck! Oh, and don't go insane while at it!

Yes, it exists so that one can switch from Scryers to Aldor. It is the same case for this quest, although this one is to switch from Aldor to Scryers:
