Naxxramas 25 Man Construct Quarter Walkthrough (WoTLK Era)
The Construct Quarter in Naxxramas has a total of four bosses, Patchwerk, Grobbulus, Gluth and Thaddius. Most raids that I have been a part of tackle this wing third, right after finishing the Plague Quarter and just before taking on the hardest of the four wings, the Military Quarter.
If this isn't the quarter you want a walkthrough for and you've made a wrong return; follow the link provided to return to my Naxxramas 25man Walkthrough Index Page. Disclaimer: Keep in mind that the guide you're reading was written during 2010 when WoTLK was the current expansion.
The links to some of the Wowhead resources may be out of date as will some of the video strategies. With that said, I can guarantee that this guide was accurate during the time it was written, abilities were copied from WoWhead and the entire guide was heavily researched as it was written. The information on this page is preserved as it was back during that era.
Patchwerk: Patchwerk is the first boss in the Construct Quarter of Naxxramas. This is the only boss in the game where your better tank is the off tank. This fight is best known as a gear check, the tanks need to be able to take a beating, the DPS needs to be able to beat the enrage and healers need to well, heal! The off tank will be keeping agro of Patchwerk while the main tank will have to make sure he is secondary on agro, and second highest health in the raid so he eats the Hateful Strikes. On Heroic difficulty you will need a 3rd tank to eat the 3rd Hateful Strike.
As a Melee class you should notice the in a slime river near where patchwerk walks that you have to continually dip into to reduce your health so you don't get Hateful Striked. The ranged DPS doesn't have to worry about this since Patchwerk only Hateful Strikes people within melee range.
Aside from Hateful Strikes Patchwerk doesn't do anything unique.
Hateful Strike: Deals 79,000 to 81,000 damage to a threatening target with the highest health within melee range.
My Advice: Like stated earlier have the main tank off tank Patchwerk to get hit with all the Hateful's and the Off Tank main tank Patchwerk to take his regular hits. If a melee gets Hateful Striked, chances are he is going to die.
Frenzy: Increases the casters attack speed by 40% and the Physical damage it deals by 25% for 5min.
My Advice: Patchwerk will use this at 5%, if any cooldowns are up like Last Stand, or other cooldowns that will increase your DPS pop them to help burn down Patchwerk.
Berserk: Increases the caster's attack speed by 150% and all damage it deals by 500% for 5min.
My Advice: After 6 minutes Patchwerk will go enraged if he is not dead. You will be.
Slime Bolt: Shoots poison at an enemy, inflicting Nature damage, then additional damage every 3 sec for 6 sec.
My Advice: This is the ability he will use when he goes enraged. It will shoot poison bolts at everyone in the raid causing massive amounts of damage.

Grobbulus: Grobbulus is the second boss you will encounter in the Construct Quarter of Naxxramas. Grobbulus will drop a Fart cloud on the ground once every 15 seconds, to avoid this cloud and all others the tank will be kiting Grobbulus around the room clockwise. Also in addition to the Fart cloud Grobbulus drops, he will also put Mutating Injection on a random person in the raid. After 10 seconds the person will be hit with some damage and drop a fart cloud on the ground where he was standing.
The person who has this debuff needs to run to a isolated part of the room away from the raid and drop the fart cloud somewhere safe. Also Grobbulus will use a ability called Slime Spray. Slime Spray deals damage to anyone 10 yards in front of him, it also will cause a Fallout Slime to spawn, the off tank should hop on the slime asap and the raid should focus on taking it out when it spawns. You should only have one spawn if everyone is doing their job correctly.
Additional Note: At 30% Grobbulus will start to use Mutating Injection a lot more frequently, making it a DPS race from here on out.
Abilities
Poison Cloud: A poison cloud appears which grows in the area for 1.25min.
My Advice: As long as Grobbulus is being kited properly this won't be to much of a problem. You can't kite him to fast or to slow otherwise you'll end up running into a Fart cloud or you'll be overwhelmed by fart clouds.
Mutating Injection: Injects a target with a mutagen that creates a poison cloud after 10 seconds.
My Advice: This disease will cause you to make a fart cloud of your own. What you need to do is run somewhere secluded and wait for the debuff to drop the fart cloud. After it's dropped you can return to Grobbulus and start DPS again.
Slime Spray: Slime sprays out, dealing 11875 to 13125 Nature damage to enemies in front of Grobbulus. Enemies hit by Slime Spray summon a Fallout Slime.
My Advice: This attack should only ever be hitting the main tank. When the Fallout Slime spawns have the off tank hop on the slime and have the raid quickly burn it down.
Berserk: Increases the caster's attack speed by 150% and all damage done by 500% for 5min.
My Advice: Grobbulus will Enrage after 12 minutes.

Gluth: Gluth is the third boss in the Construct Quarter of Naxxramas. This fight requires someone in your raid to be good at kiting. It also requires at least two tanks with the ability to coordinate with each other. The tanks will need to taunt off each other once one reaches 5 stacks of Mortal Wounds. Also someone in the raid will have to kite around the zombies that come out of the grates during the encounter.
During phase 2 of this fight Gluth will decrease everyone in the raids HP to 5%, he will also decrease the zombies health to 5%. After he casts this spell the zombies that are being kited will start to run towards Gluth. If a zombie reaches Gluth he will regain 5% of his health. All of the dps classes should focus on slowing and killing the zombies as fast as possible. After you kill all of the zombies phase 1 will start again.
Abilities
Mortal Wound: A punishing blow strikes the target, reducing the effectiveness of healing spells by 10%.
My Advice: Only the tanks have to worry about this debuff, in order to counter it, when one tank reaches 5 stacks have the other tank taunt off of him. Then once the other tank reaches 5 stacks taunt back off of him.
Enrage: Decreases the time between your attacks by 25% for 8 seconds.
My Advice: During the fight Gluth will go Enraged a few times, it can be removed with a hunters Tranq shot or Rogues Anesthetic Poison.
Berserk: Increases the caster's attack speed by 150% and all damage done by 500% for 5min.
My Advice: Gluth will enrage after 8 minutes.
Loot:
Everything that doesn't come from KT/Sapph
Thaddius: Thaddius is the fourth and lost boss of the Construct Quarter of Naxxramas. When you start the encounter you will have to kill Feugen and Stalagg simultaneously. They also must die within 5 seconds of each other, otherwise one will resurrect and you'll have to start all over. After both of Thaddius's adds are killed Thaddius will become attackable and engage the raid.
The Thaddius encounter has a similar mechanic to the first boss in Mechanar on Heroic. Basically you have to have the raid split up into two halves. One goes to the right on one goes to the left, usually its Plus to the Right and Minus to the Left. Obviously different people will use different strategies, that's why you have to listen on vent!
Stack on top of each other to make sure everyone gets the buff. Make sure someone in the raid is calling out the Polarity Shift and when it happens have anyone on the left side that gets a positive charge run clockwise around Thaddius and anyone on the right who gets a Negative charge run Counter clockwise. If you both try to run in the same direction you'll wind up zapping each other.
This encounter requires you to master this pattern. Without everyone having the rotation mastered you're going to be giving the "Facepalm Technique" a good work out.
Abilities
Stalagg's Abilities:
Power Surge: Increase the caster's attack speed by 200% for 10 sec.
My Advice: Heal through it, pop a health stone, pot or cooldown if need be.
Magnetic Pull: Pulls an enemy from the opposite platform to the caster.
My Advice: Every 30 seconds Stalagg and Feugen will switch tanks with this ability, switching threat as well.
Feugen's Abilities:
Static Field: Deals 3500 Nature damage to all nearby enemy targets.
My Advice: Have melee DPS on Stalagg and Ranged DPS on Feugen to counter this
Thaddius's Abilities:
Polarity Shift: Places ether a Negative or Positive Charge to all nearby enemy targets. Players near each other with the same charge type will increase each others damage dealt. Players near other players with the opposite charge type deal damage to nearby raid members.
My Advice: Thaddius's main move, just do the strategy I said and you won't have any trouble.
Chain Lightning: Strikes an enemy with a lightning bolt that arcs to another nearby enemy. The spell affects up to 8 targets, inflicting greater nature damage to each successive target.
My Advice: Heal the damage that is dealt, otherwise this is normal
Ball Lightning: Inflicts 17500 to 22500 Nature damage to the enemy target.
My Advice: This will only happen if there is no one in Thaddius's melee range, Solution don't let anyone leave melee range.
Berserk: Increases the caster's attack speed by 150% and all damage done by 500% for 5min.
My Advice: Thaddius will enrage after 6 minutes.
