In the Blasted Lands you can farm buffs that give you +50 stats for one hour.
R.O.I.D.S. = +50 Strength
Ground Skorpok Assay = +50 Agility
Lung Juice Cocktail = +50 Stamina
Cerebral Cortex Compound = +50 Intellect
Gizzard Gum = +50 Spirit
There are two bloodelves on the right side of the road as you enter Blasted Lands, that give you the repeatable quests to get these buffs. The very first time you do the quest, you will receive the buff, and a consumable, which you can save to use later to give yourself the buff. If you repeat the quest you will only get the consumable. You may only have a maximum of one consumable of each type, and the consumables are Soulbound. I'm quite sure you can only have one +50 stat buff active at a time.
Each different type of buff has a different quest. Each of those quests require you to turn in various animal parts which are dropped by the beasts in Blasted Lands. There are 5 types:
Vulture Gizzard
Blasted Boar Lung
Skorpok Pincer
Basilisk Brain
Snickerfang Jowl
Strength Requires : 3 Jowls / 2 Lungs / 1 Pincer
Agility Requires : 3 Pincers / 2 Gizzards / 1 Lung
Stam Requires : 3 Lungs / 2 Pincers / 1 Brain
Int Requires : 10 Brains / 2 Gizzards
Spirit : 10 Gizzards / 2 Jowls
While the consumable you receive from the quest is Soulbound, the animal parts ARE NOT. So if you're out there farming and you start getting extras that you won't need, give them to someone else that'll need them. For example, as a Rogue I have absolutly no use for the Jowls.
While warriors don't have much use for the Basilik brains and gizzards, Guildie casters would love to get some.
Nothin wrong with an extra 500 health for a raid, Or another nice bonus from these buffs.
