Before the Gate of Horror
Thassarian, aboard the Skybreaker, wants you to use the Volatile Acid to dissolve the corpses of 6 Skeletal Reavers.
The Conflagration, the ground before Corp'rethar, south of the Ironwall Rampart, is where the Lich King's elite soldiers have formed up to defend the citadel. Led by a contingent of death knights, a legion of skeletal reavers bars the way. I fear that even when these reavers fall, the Scourge will simply reconstitute them and send them back at us. I've come up with a plan to stop this, but I have no way of knowing if it will work. Take this solution and use it to dissolve the remains of the reavers.
