Obtain 20 Rotberries, 5 Disembodied Arms, and 1 pile of Flesh Giant Foot Scrapings.
I once worked for the so-called "Banshee-Queen", Sylvanas, as an apothecary. I used to admire her, but something's changed within her. She's not herself anymore.
I broke my vows with the Forsaken and joined the Crusade. Now, I use my knowledge of alchemy to seek a counter-plague agent. And the Plaguewood is the perfect place to do so.
I need to resupply a few reagents, any of which can be found within the Plaguewood. I'll pay you if you can find any of these items.
