|A Sample of Slime...|
Requires Level 48
or 3059 at Level 90
Gather Felwood Slime Samples from any of the slimes in Felwood. Then, using the Testing Equipment next to Chemist Fuely in Undercity, see which of your samples are the most corrupt. Bring 5 of the Corrupted Felwood Samples you find to Chemist Fuely.
Felwood is a forest far north of the Barrens, even farther than Ashenvale. There, slimes are found all around pools of water blessed by the touch of Fel. The Scourge decimated the area with attacks of Infernals and other demonic magics--the slimes supposedly crept up through the earth during these attacks. Gather samples of Felwood slimes and we will use the testing equipment next to me to create a control group for our tests against other samples you gather.
I will need at least five corrupted samples for our control group, <name>. Continue to gather Felwood slime samples until you're able to give me that which we'll need. The Lady Sylvanas decrees it...
Ah, excellent. These samples will do nicely. I thank you for your help. Once we've gathered all the samples of slimes, we'll be able to determine more. I am beginning to suspect that Lady Sylvanas' hunch was not only correct, but more insightful than even she could have predicted. These samples are very interesting. Just seeing how they've reacted with my compounds... hmm, yes, we'll definitely need to investigate further.
Upon completion of this quest you will gain:
Kill any of the various oozes in Felwood. Each one will drop a .
Then, return to the Undercity, and use the Testing Equipment (via the repeatable quest  ) on each sample. This turns each Felwood Slime Sample into a . Open all the tested samples, which will hopefully give at least 5 Corrupted Felwood Samples for this quest.
It is recommended to get at least 20 Felwood Slime Samples, and to test them all before turning in this quest. Not every one will result in the required quest item (rate is about 30%), but each will at least contain some junk to sell, or useful consumables, and cannot be tested once this quest is complete.
