The power of a disenchanted magical item is felt by the essence it creates. I've devised a way to turn raw essence used by enchanters into a suitable reagent for creating Cenarion plant salve. You don't need a Cenarion beacon for this; any suitably disenchanted item that yields lesser nether essences will work.$B$BI just need a single lesser nether essence; in exchange, I will give you Cenarion plant salves. The essence is extremely potent - a little definitely goes a long way!
