Scourge of Zem'lan

Scourge of Zem'lan is a quest achievement that is earned for killing 20 of the pirates in the Port of Zem'lan in Vol'dun with Ol' Bonebite at your side.

Strategy
There are three kinds of interactable objects at the Port of Zem'lan. Each of them grants you a 10 minute buff:


 * Pirate Hat grants Thirst for Adventure
 * Zem'lan Blackeye Brew grants Thirst for Brew
 * Treasure Map grants Thirst for Treasure

Once you have all these three buffs at the same time, Ol' Bonebite will spawn and follow you as long as these buffs exist. Each object has a respawn timer of about 15 minutes. The objects do not glow or show the outlines.
