Two alternating phases. A boss phase, and an adds phase. On the adds phase in Normal there are three adds, Three normal adds called Acquisition, Guardian and Degeneration.
Acquisition increases your damage taken and does massive knockback.
Guardian spawns a floating orb that does damage periodically.
Degeneration spawns lots of little adds.
There is an additional add on heroic that creates a shield for the other adds.
Pull boss to an edge of the room and face away from the raid, whilst the rest of the raid group stacks up loosely behind the boss.
Several players will get a circle around them that, when expires, leaves a star in it's place - they should move to the outside edge of the room to drop it. Don't stand in them or they leave a permanent puddle. Drop stars as tightly packed as possible to aid clearance.
Some players will get a yellow arrow and yellow circle, and the debuff Deconstruction Energy. Cover stars with the circle to get rid of them.
Boss does a knockback - don't get knocked into stars.
Watch out for boss frontal cone.
Tanks - one tank takes every cast of Resonance, other takes Sundering Resonance. Both do damage to anyone within 12 yds, with increased damage to one who has the other debuff.
Add phase starts when boss gets to 100 energy.
Adds will start activating on the circles around the room and boss will pulse stacking debuff.
Wait until the boss is around 80 energy then check which adds a spawning.
You can either split raid into two and try and kill two before they activate, or everyone go to one to definitely down it.
Everyone stand in a golden circle around an add to clear the debuff.
If an add activates before you kill it, it will activate at 100% health.
Add kill order: Acquisition > Defence Matrix (Heroic only) > Degeneration > Guardian.
Once boss phase starts again, finish off adds asap.
