• The instance is full of lobster and crab type creatures. If you're wearing cloth or leather armor, be careful about pulling aggro. Be wary of the female naga casters and the elite guards. The female casters can mind control, and the elite guards have a magic shield that pops every now and then that renders them immune to damage. Something similar to the paladins bubble.
• Mennu the Betrayer can be found patrolling a ramp surrounded by groups of other MOBs. He's a hard hitting boss and he pops totems every now and then. A quick kill is a must.
• Rockmar the Crackler is a giant lobster. He seems simple enough, but he's got a debuff called grievous wound that causes damage-over-time to any opponent he's in close combat with.
• Quagmarran is a giant swamp creature with tentacle arms. He has a cleave attack that can hit everyone in his front arc. He also has a poison volley attack that hits everyone in about a 40 yard range. He also has a poison debuff that did 600 - 800 damage a tic. Ouchies. Given his abilities and the fact that he hits hard, tanking to protect your team can be difficult.
