Bring 4 Venomtail Poison Sacs to Kor'ghan in Orgrimmar.
Venomtails are some of the deadliest scorpids in Durotar. It was unwise for Rhinag to hunt them without having some of the antidote with him, but right now, chastising is the last thing he needs.
Bring me a few venomtail poison sacs from any of the venomtails near the entrance of Orgrimmar and I'll make an antidote for him.
Make haste, [player]. One of our own needs your help.
