“Thaddius, built from the flesh of women and children, it is said that their souls are fused together – eternally bound within that foul prison of flesh.”

Throughout Naxxramas you may have heard screams of a woman crying for help — meet Thaddius, the Flesh Titan.


Gear requirements

Like most Wrath of the Lich King raid encounters, this fight is tuned for players who are using level 80 epic gear, as well as the best flasks and food buffs available. Getting the best possible gear for your character will make this fight a whole lot easier.

In WotLK, professions can be used to craft high quality epic gear. Most raid bosses also drop an epic bind-on-equip item. These items are the easiest way to get your character geared up fast, but they’re expensive to craft or buy on the AH. The easiest way to get your hands on them is to use a guide like WoW Gold Secrets, which has tips for making several thousand gold per day. This is a great way to save time and down bosses faster.

On the Pull

Raid The raid should split up into two groups for Feugan and Stalaag, generally your dps should be split evenly between the two as they both need to die within seconds of each other. Both groups need to engage their respective targets at the same time, and should coordinate using voice chat.

Healers An AOE healer should go with the Feugan group while a single target (such as a Paladin) goes with the Stalaag group.


Phase One

Downing Stalaag and Feugan will be considered as phase one.

Tanks You must each engage your targets at the exact same time; use voice chat to synchronize your actions.  Throughout the fight you will be thrown by either Stalaag or Feugan onto the opposite platform where you must begin fighting for aggro each time you land.

DPS You must communicate between your two groups to determine which group needs to speed up dps and which may need to slow down. Once both mini-bosses are at around 5% health, go all out and down them both.

Healers Keep your tanks alive, Feugan’s group healer must heal the raid as well.


Phase Two

Raid With Feugan and Stalaag down, the tesla coils will zap Thaddius, bringing him to life after a few moments. Both groups need to jump off of their platforms and onto Thaddius’ ledge. When Thaddius becomes targetable, the real fight begins.

A few seconds after the fight begins Thaddius will cast Polarity Shift. When he does this, you will get either a positive or negative charge. Depending on the Charge you received, move to the appropriate marked area in the diagram. Negative charges should gather at the edge of the ledge beside Thaddius, and Positive should gather against the wall. Within your Charge group, stay as close to each other as you can to benefit from the increased DPS conferred by the Charge.

Thaddius will re-cast Polarity Shift every so often. Whenever your Charge changes, move to the appropriate area for your Charge as quickly as you can.

Tanks You must grab Thaddius when he becomes active and drag him a few yards to the right, which allows more of the Ledge to be accessed making it easier to switch sides. You also need to pay attention to what charge you have and adjust accordingly

Melee DPS You will be the markers for everyone to group up on. Stay at your maximum melee range from Thaddius; it is your job to stay at your max range from Thaddius while still paying attention to your charge. The raid will be grouping as close as they can to you in order to maximize dps.

Ranged DPS, Healers Keep note of where the melee on your side is. You’ll need to be close enough to them to share your Charge with them and receive the buff they give you as well.


As long as nobody crosses charges, this boss is ~shockingly~ easy to take down.

You will be marked with a debuff, a negative charge is a blue debuff with a – sign, and positive is a red debuff with a + sign. Your character will also pulse these colors when you are charged.

I have only gotten to this boss one time and yes it was a fail, partly cause i could never tell which way i was charged. Is the problem caused by the fact i had to reduce my video settings to stop the lag problem or is there possibly a glitch. It was not just me but from the way people where dyeing because of it only select toons changed polarity. I have search for an answer on line and not found any screen shots showing how the polarity is marked or what i should be looking for.
