The desert kingdom of Uldum is home to multiple Cinderbloom nodes, as well as the only area with Whiptail spawns (except for the tiny little crocolisk swamp in Tol Barad, but the competition is so high there regardless that it is impractical and therefore insignificant. >_> ) Uldum is designed to be accessed at level 83, although technically a character can fly into the zone at a lower level and farm. The most common and popular route in Uldum is following along the central river. This path will only provide Whiptail, therefore I threw in a path (grey) I would most likely use for Cinderbloom as well. Feel free to mix up the two or design your own path, although unless you also have mining it will be most profitable to stick to the middle Whiptail route.
Now…a word about Whiptail. At least as of this post, Whiptail has been buffed and is at a near instant spawn rate. Most herb farmers know this, which makes Uldum an extremely popular spot for flower picking – but luckily because of the insane spawn rate, more farmers almost always means even more Whiptail popping up out of the ground! Unless you are a druid and can stay in flight form while grabbing herbs, you may have to fight off some grumpy native wildlife, but usually the crocolisks will die in a matter of seconds.
At least until this spawn rate is nerfed, Whiptail remains a gold mine, and Uldum is easily the most profitable zone for pure herbalism. Personally, I have made over 40k gold in less than two days farming this stuff. Next, we will be discussing Twilight Highlands herbs!
