Ok, I searched, couldn't find anything, here goes:
Ok, so for the final part of the Warlock Epic mount quest, you need J'eeve's Jar, Xorthian Glyphs, and Black Lodestone, if you've done this, you can keep the mats after doing it! So, what I do, grab a friend or two, and advertise something catchy like "Are you a Warlock? Just hit 60? Need a Mount? Can't find the money? Then -------'s epic lock mount service is for you! You don't even have to buy the reagents, only 50g for your epic mount, and hey, that's better than 150g for the reagents!" then run locks en masse to DM west and get their mount! It's a great way to make money, hope you enjoyed the guide!
