Thaddius - Naxxramas boss guide

Tactics for Thaddius in Naxxramas 10/25 for WoW 3.3.5a: Stalagg and Feugen, famous jump, Polarity Shift, loot and T7 tokens.
Review
Thaddius is a flesh titan, the final boss of the Abomination Quarter, made "from the flesh of women and children." The battle is in two phases: first, the raid is divided in half and simultaneously kills two mini-bosses on the platforms - Stalagg and Feugen (if you don’t kill them almost simultaneously, they will come to life with full HP), then the famous jump onto Thaddius’ platform and the battle around the Polarity Shift: “pluses” to the right, “minuses” to the left, charges of the same name buff each other’s damage, charges of the same name explode the raid. Drop of T7 tokens on your feet.
- Jump onto the platform: autorun, jump from the edge strictly straight, not diagonally. Slow fall/Levitation or speed potion insures. Missed - run around and enter the battle ONLY after receiving a charge.
- Stalagg and Feigen should die within seconds of each other (according to the server script, the window is ~5 seconds) - manage their HP synchronously and slow down the DPS at a faster rate.
- A player without a charge (brez, latecomer) catches damage from both polarities - stand aside until Thaddius releases a charge.
- FD Khanta, the disappearance of rogues and soulstones before the boss respawns after a wipe, bugs the combat team for the entire raid - classic Thaddius, ban it in advance.
- Each dead person is a minus damage stack buff for his entire side: raids with corpses more often do not survive to berserk, rather than with low gear.
Combat phases
The raid is divided into two equal groups according to platforms: Stalagg on the left, Feugen on the right, each at his own Tesla coil. Every 20 secMagnetization swaps tanks - the healers transfer the heal to the arriving one. You cannot pull bosses away from the coils: when the chain breaks (~28 m), the coil begins to hit the entire raid with Tesla shock. Kill both almost simultaneously, otherwise the living one will resurrect the dead one with full HP.
- Magnetization (tank swap)
- Wave of Power at Stalagg
- Electrostatic field at Feigen
- Synchronized kill (~5 sec window)
The entire raid jumps from the platforms towards Thaddius. After 20 seconds - firstPolarity shift, then every 30 sec: “minuses” appear on the left, “pluses” on the right, clustered within 10 m for a damage stack buff. The charge has changed - you cross to the other side along one pre-agreed route. They fly in parallelChain lightning, and if there is nothing in the mile-radius -Ball lightning at 17–22k. In 6 minutes -berserk.
- Polarity shift every 30 sec
- Stack buff from charges of the same name
- Chain Lightning
- Ball lightning with empty mile-radius
Abilities
Positioning
Phase 1: two equal groups (tank + heals + dps equally) on the platforms of Stalagg (left) and Feugen (right), bosses tank at their tesla coils, do not take them away from the platforms. Phase 2: Jump to the lower platform; "cons" to the left of the boss, "pros" to the right, both piles compactly within 10 m of each other.
Role Tips
- P1: do not drag Stalagg and Feugen away from the Tesla coils - breaking the circuit charges the coil with Tesla shock throughout the raid.
- P2: not a second outside the mile-radius -Ball lightning 17–22k in range more expensive than any repositioning.
- The DPS that has surpassed the tank in terms of threat on mini-bosses will fly away onMagnetization will die instead - watch your group’s aggro.
- After the jump, instantly pick up Thaddius: firstPolarity shift will arrive in 20 seconds.
- P1: after each tank swap (every 20 sec), instantly change the healing target - the arriving tank is already drained of HP.
- Wave of Power Stalagga - windows of double damage to the tank, keep BoL/shields/hots under them in advance.
- P2: change of side according to charge - with a heal on yourself; in a crowd it’s easy to catch a couple of ticks of 4500 while neighbors are jogging.
- Don’t rush anyone into a pile: a player raised without a charge catches damage from everyone - the rush is on the sidelines, the player waits for the next shift.
- Stand as closely together as possible with your polarity: the damage stack buff is the reason why the dps on Thaddius is 2-3 times higher than usual, without it you won’t be able to complete it in 6 minutes.
- Look at your debuff after EVERY cast, and don’t follow the crowd: not everyone’s polarity changes.
- Do not summon Pets and Mirror Doubles on mini-bosses - they run away to someone else’s platform and stretch out the bosses.
- Hiro - after the firstPolarity shift; the second will go to the end of the timer.
