My Enemy's Enemy is My Disguise

Objectives
Speak with Magister Umbric to be disguised as a blood troll.
 * Blood troll disguise complete

Description
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.

Rewards
You will receive:
 * 1,790 XP
 * 1,790 XP

Progress
I know this is unpleasant, but it must be done.

Completion
I have to admit, this disguise is uncanny. Let's hope the zandalari believe they are dealing with a bold blood troll and not the Alliance.
