Summary

The XT-002 Deconstructor fight is one of my favorite fights in Ulduar, and is considered by many to be a “free epics” fight.  The amount of raid damage keeps healers on their toes, while the adds and heart phase of the fight makes the DPS happy.  It’s a simple 2 phase fight with a hard enrage.  The Deconstructor is one of the four bosses you must kill in order to receive the Heroic: The Siege of Ulduar achievement.

Recommended Raid Composition

You will need two tanks for this fight; one to tank XT-002 the whole time, and another to tank the large Pummeler adds that he spawns during his Heart phase.  6-7 healers is normal for this fight, and you will probably want to assign group healers to certain groups to keep the raid topped off during Tympanic Tantrum.  As far as DPS is concerned, you should be able to bring whatever classes you like, but I do recommend assigning AoEers (I usually just tell my mages to handle this) to attack the Bomb Bots and Scrap Bots during this fight.

XT-002 Abilities and Add Abilities

Tympanic Tantrum – Does a total of 120% of your health evenly throughout twelve seconds.  Even if your healers aren’t the best, your raid can survive this off a simple health stone or health potion.

Gravity Bomb and Light Bomb – These are two things that DBM will mark people for and they will have to run out of the raid group for to keep the raid alive.  The Gravity Bomb ability will drag people to it once the debuff wears off, while the Light Bomb ability will deal damage to everyone in range of the person until the debuff wears off.

At every 25% of his health, adds will appear from the 4 junk piles at every corner.  There are Scrap Bots, Boom Bots, and Pummelers, which need to be dealt with.  Pummelers will need to be tanked for the duration of the fight by your OT (they don’t hit hard), Scrap Bots should be AoE’ed down, and Boom Bots should be focus-fired down by your ranged, and hopefully near Scrap Bots (they deal damage to everything when they explode).

The XT-002 Deconstructor Fight Strategy

Engage the Deconstructor, ensuring to fully HoT up your main tank while the raid gets into position.  In the image below, you can see where we tank XT-002, in between two of the junk piles on either end of the room.  The reason for this is that he WILL NOT SPAWN ADDS ON THE TWO JUNK PILES HE IS TANKED NEAR. That is crucial to this fight, and getting some of the achievements that this fight can offer.

It shouldn’t be any problem keeping your tank or raid up (even through Tympanic Tantrum), and DPS heavily.  At 75% he will enter his first heart phase.  I recommend popping Heroism/Bloodlust during the first Heart phase, and if your DPS if somewhat decent, you should be able to bring him at or near 50% (the next Heart phase), when he is re-engaged.

All of your DPS should be focusing on the heart during the beginning of this phase, and your OT should be picking up the Pummelers (they have too much to kill them).  As I mentioned earlier, I usually assign my 3 mages to AoE down the Scrap Bots and Bomb Bots, which can heal the boss for 1% of his total health (each individual bot), and we usually end up doing it cleanly.

Depending on how competent your raid is, you can either stay clumped up into a couple of groups during the fight, or stay spread out.  Each method has its own pros and cons; we used to stay clumped in 3 groups (1 melee group, 2 ranged groups), but now that we have perfected the fight we just let everyone stand where they want and run out when they get either of the debuffs.  That is up to you.

Using the placement I recommend will save you a lot of difficultly on this fight, as placing him in the middle of the room will allow adds to spawn from all 4 quadrants of the room, and should really simplify the entire fight.  Make sure you don’t kill the Heart while DPSing it (doing so activates hard mode), and you should have this one in the bag in no time.
