Ol' Bonebite

Ol' Bonebite is a skeletal bird of prey that spawns to accompany the player in the Port of Zem'lan in Vol'dun while they have the Thirst for Adventure, Thirst for Brew, and Thirst for Treasure buffs active. Bonebite remains by the player's side as long as all three buffs persist. Killing 20 pirates in Zem'lan while accompanied by Bonebite rewards the Scourge of Zem'lan achievement.
