We need you to kill several targets within Warport Rastari, but we also cannot reveal that the Alliance is here.
Umbric has uncovered a ritual from Nazmir that will grant you a blood troll disguise. It is grim, but it must be done.
You will go through with the ritual, then use my invisibility flask to sneak into the Warport.
If discovered, the Zandalari and Horde will think it's a bold attack from the blood trolls... and not from the Alliance.
