We beat our heads bloody against this boss for a number of weeks only to have it finally come together. In the second phase around the 20% mark on Entropius you start to get that shaky, sweaty feeling in your hands and your mind starts racing and you start yelling "KILL IT KILL IT!" And then when he finally dies everyone on Ventrilo goes nuts and you collapse on your desk in exhaustion. THAT is a boss kill.
