Rift Mob:Rusila Dreadblade  

Second earth wing boss of the Infernal Dawn 20 man raid instance released April 2012 along with patch 1.8.

Rusila is a simple fight that comes in two phases. The first phase the players have to deal with Rusila's ship mechanical defenses.

Once complete Rusila becomes active, phase two begins and she starts gaining stacks that increase the damage she can deal.

Rusila goes through the same rotation of abilities again and again and becomes simply a fight of proper raid positioning.
