Felwood- drops almost everywhere
Progress
Possessing a Cenarion Beacon allows one to see a corrupted soul shard on those tainted beasts that are put down for the greater good. I grind shards into a usable reagent that goes into making Cenarion plant salve. We will use that salve to turn corrupted plants into healthy ones again.
In exchange for these shards, I will give you some Cenarion plant salves I have already prepared.
Completion
Very well then, here are your Cenarion plant salves. Scour Felwood for corrupted plants, <name>! Wherever they are, use the salve I have given you to purify them.
