XT-002 Deconstructor - Ulduar boss guide

Tactics for the Destroyer XT-002 in Ulduar 10/25 for WoW 3.3.5a: Peals of Fury, Searing Light and Gravity Bomb, heart phases, junkbots and boombots, heartbreak hardmode and full loot.

Ulduar
10N10HC25N25HC
⏱ Berserk: 10 minutes (in the script `EVENT_ENRAGE, 10min` → spell 26662). It works both in normal mode and in hardmode - that is, hardmode does not add a separate timer, it just increases HP by one and a half times with the same limit.

Review

XT-002 is a clockwork giant built by Mimiron; the machine considers itself his son and behaves like a capricious child. The fourth boss of Ulduar (or the second if you skip Razorwing and Ignis). The battle is simple in terms of mechanics, but demanding on spread and healing: two run-up debuffs (Scorching Light and Gravity Bomb), raid Peals of Fury at 10% HP per second and heart phases at 75/50/25%, where waves of robots climb out of piles of toys. Kill an open heart = enable hardmode: Heart Rip, no more robots, but an evil boss with void zones and Living Sparks.

General tips
  • The debuffs are laid out like on Thaddius: the raid is in a group, the Scorching Light runs in one direction, the Gravity Bomb in the other, the paths do not intersect.
  • The scorching light hits ALLIES around the target, the Gravity Bomb explodes after 9 seconds and ATTRACTS everyone within 12 meters - that's why the points are different.
  • Peals of rage hit at 10% of maximum HP per second - a percentage, not a number: stamina does not help here, only healing saves.
  • Junkbots heal the boss for 1% of maximum HP each. If you missed a dozen, you got 10% of the strip back.
  • Boombots explode at 50% HP, and not upon death (in the script `damage >= health - maxHealth*0.5` → Boom). The boom hits both players and robots - this is your main AoE against junk bots.
  • Hardmode is activated by killing the heart in ANY heart phase, not only the first. The first one is simply the most convenient.
  • Achievement “Must Deconstruct Faster” - complete in 4 minutes, the timer starts from the pool.

Combat phases

Phase 1 Phase 1 - Boss Pool and after each cardiac phase

Regular tank-and-spank with three things per head. Searing Light - the first time after 11 seconds (10) / 9 seconds (25), then every 20/16 seconds. Gravity Bomb - the first time after 21/18 seconds, then every 20/16 seconds. Pealsrage - every minute. After the heart phase, the timers restart shorter:Searing Light after 25 sec, bomb after 15 sec (10) / 33 sec (25), Rumble after 25 sec.

  • Splitting two debuffs at different points
  • SurvivePealsrage
  • Miles behind you, range in a bunch
Phase 2 Heart phase 75%, 50% and 25% HP (there are no more phases in Hardmode)

The boss says emote, after 6 seconds opens his chest and for 30 seconds becomes invulnerable and passive, and the Heart of the Destroyer (NPC 33329) becomes vulnerable and takes +100% damage. ALL damage to the heart is transferred to the boss one-on-one - therefore the heart phase is not a pause, but a burst window. The heart radiates energy into a pile of toys, waves come out from there: 1 boombot, 5–7 junkbots, and with a 30% chance oneXM-024 Crusher. After 30 seconds the chest closes, the boss gets up and everything starts again.

  • All damage in the heart is transferred to the boss
  • Don't miss the junkbots to the boss
  • Boombots as AoE against junkbots
  • Just tank the crushers to the side
Phase 3 Hardmode - Heartbreak Finish a heart in 30 seconds of any heart phase

The heart dies → the boss is instantly healed to full strength and receivesHeartbreak (+15% damage, +50% HP), heart phases no longer occur and robots do not spawn at all. In returnGravity Bomb leaves after the explosionVoid zone for 3 minutes, andSearing Light upon expiration, summons a Living Spark. Then it’s a pure race of damage and healing against the same 10-minute timer.

  • Accurate placementVoid zones - they don't disappear
  • Tank picks up Living Sparks
  • Race with timer for +50% HP

Abilities

Peals of Fury
Raid damage F.1
Every minute, cast 2 sec: 10% of each target's MAX HP once per second for 8 sec, plus dizziness for 2 sec. It only hits players and pets (targets are filtered in the script).
Action:All healers should join the raid, no one is left without healing for these 8 seconds. Especially those who are currently wearing Scorching Light or Gravity Bomb. The paladin can first pull down and then turn on the Divine Sacrifice - then it will work in its entirety. IMPORTANT: the tooltip in the client still says 12 seconds - Blizzard cut it to 8 with a hotfix in 3.1.2, but the text was not corrected.
Searing Light
Debuff F.1
On a random player for 9 seconds: the target receives damage once per second and burns all allies within 10 meters for ~3000 (in 25 ~3500, spell 65121). In Hardmode, after the debuff expires, a Living Spark is born.
Action: Run back to your designated point immediately, without interfering with the bomb carrier. It's a good idea to keep the wearer at the top - the debuff will not be dispelled.
Gravity Bomb
Debuff F.1
For a random player: after 9 seconds, an explosion of ~12,000 on the carrier (in 25 ~ 15,000, spell 64234), plus 11,700–12,300 damage from darkness (25: 14,625–15,375) to everyone within 12 meters and attracting them to the carrier. In hardmode, a Void Zone remains at the site of the explosion.
Action: Run away in the opposite direction from the Scorching Light. The Mage's Ice Block and the Paladin's Divine Shield remove the entire explosion. Rogi: Haste + Cloak of Shadows = reset the zone to the far corner and return. If someone died from a bomb, the achievement “Beware of gravity!” flew off.
Repairing junk
Other F.2
Junkbots (NPC 33343, ~6,400 hp in 10) run to XT and, having reached him, each restore 1% of his total health. Wave - 5–7 pieces.
Action: Kill before they get there. The cheapest way is not to burn mana on AoE, but to blow up a boombot next to them. Achievement “Engineering sucks!” requires that NOT ONE junkbot finish healing the boss.
Boom
Other F.2
Boombots (NPC 33346, ~12,600 HP in 10) go to XT and explode either on contact with him or when their HP drops to 50% - that is, you only need to blow up ~half of the bar. Explosion ~15,000–18,000 for everyone nearby, including robots.
Action:Range priority, but not “kill”, but “let down and blow up in a pile of junk.” A boombot sent to the boss also causes damage to him - just warn the miles. ~25,000 total damage is enough to trigger Boom.
Arc Kick
Other F.2
Thick melee add (NPC 33344, ~252,000 HP at 10): Arc Strike (8374) with a cone, Stomp (5568) and Uppercut (10966) on the target.
Action: Off-tank picks up and holds. In normal mode - just under the cleave next to the boss, he will die from the AoE. In hardmode (if the crushers managed to get out before killing the heart) - take them aside and ignore them until the end of the battle.
Naked Heart
Other F.2
For 30 seconds, the heart receives +100% damage, and each hit to it removes health from the XT itself. It is possible to break through the threshold - with sufficient damage, the boss goes into the second heart phase immediately after the first.
Action: All CD and hero go here, this is the best damage window in battle. But if the heart reaches zero, hardmode will turn on. If you don’t want hardmode, keep an eye on the heart bar and switch.
Heartbreak
Other F.3 HC
Hardmode buff: “all combat restrictions of the Destroyer XT-002 have disappeared.” Damage +15%, health +50%. The boss instantly heals completely, heart phases no longer occur, robots do not spawn.
Action: The decision is made once and there is no going back. In 25 the ID is different - 64193.
Void Portal
Other F.3 HC
Only in hardmode: at the site of the Gravity Bomb explosion, a zone (NPC 34001) remains for 3 minutes, causing ~5000 damage per second to those standing in it (in 25 ~7500, spell 64235).
Action: Each bomb carrier places a zone in a predetermined corner, in a circle - otherwise by the middle of the battle the raid will have nowhere to stand. The zone lives for 3 minutes, and not until the end of the battle, as icy-veins writes - on a long pull, the first ones have time to fade away.
Static charge
Other F.3 HC
Only in hardmode: after the Searing Light expires, a Living Spark (NPC 34004) is born with an aura of 800 nature damage every 3 seconds across the ENTIRE raid (aura radius 500 m), plus Shock (64230) to its target every 12 sec.
Action: Taunt and instant focus - sparks stack, and each living spark is another 800 damage to the raid every 3 seconds. The wowhead guide writes “500 damage” - they confused the damage with the aura radius of 500 meters; in the tooltip the buff costs 800.
Berserk
Berserk
Exactly 10 minutes after the pool (in the script `EVENT_ENRAGE, 10min`). Works the same in normal mode and in hardmode.
Action: In normal mode, the timer is generous. In hardmode, this is the main difficulty of the battle: +50% HP with the same limit.

Positioning

Raid in a dense group in front of the boss (for chain healing and AoE), two designated points on the sides: on the left - Scorching Light, on the right - Gravity Bomb (or vice versa, the main thing is that the paths do not intersect). The tank holds the XT in place, miles behind him. In the heart phase, nothing moves: the range works on robots from the group, miles - on the heart. In hardmode, the bomb point “walks” in a circle so that the Void Zones lie in a chain along the edge, and not in the center.

🛡 Tank
There is nowhere for the boss to turn around - he has no cones, but he still has miles behind him out of habit. The main job of the off-tank is to pick up the Crusher in the heart phase and move them away so that they do not trample the healers, plus in hardmode the instant taunt of Living Sparks. Watch out for the stray robots - they run straight towards the healers.
✨ Healer
Peals of Fury are the main source of damage in battle: 10% HP per second for 8 seconds in a row throughout the raid. No one should be left without an assigned healer. Separately: The bearer of Scorching Light stands alone to the side and receives a tick every 9 seconds. Hardmode adds a constant background from Static Charge - keep Living Sparks dead.
⚔DD
In a bunch, but with an eye on your debuff: if you saw a Scorching Light or a Gravity Bomb, you ran to your point without thinking. In the heart phase, all damage is in the heart (it is transferred to the boss), except for the assigned range against boombots/junkbots. Keep knockbacks, slows and stuns ready: a robot that breaks through to the healers is a wipe.

Role Tips

🛡 Tips for the tank
  • Smashers in normal mode do not require killing - drag them under the cleave next to the boss, they will die from the raid AoE.
  • In hardmode, the Living Spark must be picked up instantly: while it is alive, the entire raid eats 800 damage every 3 seconds.
  • XT in hardmode hits only 15% harder - the bottleneck of the battle is not the tank, but the raid damage and timer.
  • The stray junkbots and boombots follow the normal aggro table and will run towards the one who hit them - warn the range.
✨ Tips for healer
  • Pealsrage - a percentage of the maximum, not a fixed damage: gaining stamina against them is useless.
  • Paladin: go down, and then Divine Sacrifice - it will work out the entire duration and remove a huge chunk of raid damage.
  • CarrierGravity bomb gets ~12,000 (15,000 in 25) in one tick after 9 seconds - keep it in the top by the time of the explosion.
  • Rezto the shaman reveals itself at Raskatah: the raid already costs a lot for the sake of distributing debuffs.
⚔ DD Tips
  • Do not kill the boombot alone - take it to a pack of junkbots and blow it up there, this will remove the entire wave in one fell swoop.
  • The boombot explodes at 50% HP, not on death: ~25,000 total damage is enough.
  • Damage to the heart = damage to the boss one on one, and even with +100%. This is the best window in battle, burn your hero here.
  • If you don't want hardmode, look at the heart stripe. If you want, go for it, and this can be done in ANY phase of the heart, not only in the first (icy-veins writes “only in the first” - this is incorrect).
  • Hardmode Rogues: Haste + Cloak of Shadows = AttributeVoid zone to the far corner and return without causing damage to yourself.
