Re: [MoP] Farming rares for their unique item or achievement I have about 2 dozen rares killed. The best thing I have is an item from a Jinyu in valley of 4 winds, when used it grants you symbiosis effect, 1hr cooldown, persist through death. Free rejuv every 10 sec on my demon lock means I never die doing quite large aoe pulls
I camped the Ghostly Pandaren Fisherman for the lure that drops that gives you a chance to find additional fish from pools in Pandaria. Took about 17 hours, and only respawned after rolling restarts on Tues. About a dozen other people were there, luckily I was able to get in right away and spam my macro.
It also gave me an achievement, but then like the rare-mob one, expands into a new achievement to collect 5 rare items. From there, I am told all the way up to all of them for a title, Relic Hunter. No way in hell am I going to camp 12+ hours for each one, though.
