Securing the Shaleskin Shale

Objectives
Collect 5 Shaleskin Shale and give them to Boots at Area 52 in the Netherstorm.
 * Shaleskin Shale (5)

Description
I make a good living selling drinks to the boozehounds around here. But I want something more! The rocket-chief is always telling me how he can't perfect the rocket fuel needed to get the X-52 off of the ground. We can solve that little problem for him. For starters I need to extract the oil from the shale of the local shaleskin flayers! It'll form a concentrated, if explosive, base for the mix that I have in mind. Find the flayers, and their shale, all over the place near the purple rocks.

Reward
You will receive:

Progress
You have enough of that shale yet? I'm going to need a lot of it to extract the amount of oil that'll be needed for the X-52 Nether Rocket's fuel.

Completion
OK! Ingredient number one is down. Now, if you're up to it, we'll move on to something that'll give the shale oil that little extra kick that it'll need to blast the nether rocket into the Twisting Nether... or oblivion, whichever comes first.

Gains
Upon completion of this quest you will gain:
 * 12000 XP (or at level 70)
