Use the Aspect of Neptulon on poisoned elementals of Eastern Plaguelands. Bring 12 Discordant Bracers and the Aspect of Neptulon to Duke Hydraxis in Azshara.
A force of elemental scouts was sent to the eastern plaguelands of Lordaeron, and the disease of that place twisted and infected them. The Waterlords cannot allow this affront to our purity!
Take this vial. In it is a quantity of one aspect of Neptulon. If used on the plagued elementals it will fight the poison within their bodies and cure them! But their inner conflict will drive them into a surging madness.
Defeat the discordant surges and bring me their bracers of binding.
