Krystallus

Krystallus is a boss in the non-linear instance of Halls of Stone. He is an enormus colossus at the end of the cavern-like room.

''War isn't won by might alone; it is won by armies. This inherent truth inspired Loken to order the creation of loyal stone constructs to bolster his legions. Krystallus was chosen to oversee the operation and to crush any interloper that threatens its work.''

Two manning

Interestingly enough, Krystallus can be killed with just one heroic geared (crit-immune) tank and one healer, no dps, although it may take some time. The key is keeping your toons more than 20 yards apart. That way the healer should be able to heal the both of you without ever running out of mana.
