Speak to the quest giver to complete it.
Progress
A Cenarion beacon will allow a well-trained skinner to spot patches of tainted skin from bounty gathered in Felwood. I convert these seemingly useless patches into a thick paste that serves as a quickening agent for Cenarion plant salve. When you skin your kills here in Felwood, be sure to have a beacon on you!
When you collect tainted patches, bring them to me and I will give you some Cenarion plant salves that I have already made.
Completion
This is exactly what I need. Here - take these plant salves and use them to reclaim Felwood from the corruption. We must persevere, adventurer!
