Blackwater Behemoth, an underwater encounter, is the second or third boss of Azshara's Eternal Palace, found in The Grand Reception wing. A notable drop is the
Sangueduro Senzamente battle pet.
Learn how to defeat this underwater boss in the
Blackwater Behemoth Guide by FatbossTV.
If you're interested in other underwater zones, check out the controversial leveling zone of
Vashj'ir, added in Cataclysm. Players receive underwater breathing, swim speed buffs, and eventually a sea horse mount early on in questing to make transportation easier. Players learn about the history of the Highborne, as this city was home to Lady Vashj before the Sundering, as well as the threat of Ozumat, culminating in a battle between Neptulon and the naga.
This zone was originally intended to have further dungeons and quest hubs in 4.2, but that was dropped in favor of developing Firelands and the Molten Front.
Kelp'thar Forest is the first subzone players reach when questing in Vashj'ir. It has tropical underwater life and is closer to the surface than other subzones. Quests introduce the threat of the naga while also reacquainting the player with stranded members of the Zul'Aman exploratory crew.
The
Shimmering Expanse is the second subzone of Vashj'ir. It contains
Circolo della Terra quartermaster in Silver Tide Hollow, the only flight points in the zone, and tons of
Velo di Azshara. In this section, players learn about the highborne's past and the threat of the naga through the eyes of Battlemaidens.
Poseidus, who drops
Redini di Poseidus, is mostly likely to spawn in this subzone too.
Abyssal Depths is the last, and darkest zone, players reach when questing in Vashj'ir. They are home to the ancient god L'ghorek, which the Twilight Hammer is siphoning energy from to be prepared when fighting Neptulon in the future.
