Death Knight - Réanimation d'un allié (Battle Rez)

Druids - Marque du fauve and Renaissance (Battle Rez)

Mages - Intelligence des Arcanes (Raid buff)

Paladin - Intercession (Battle Rez)

Priest - Mot de pouvoir : Robustesse and Infusion de puissance (Raid buffs)

Warrior - Cri de guerre (Raid buff)

PreparationChromie TimeChromie TimeChromieimmensely important

If you group with a friend who picked a different expansion than you, you can also queue for their expansion's dungeons as long as they remain in the group.

You do not necessarily need to return to Chromie every time you want to change expansions. While you will need to select an expansion to gain initial access to certain zones, such as the Broken Isles, Outlands, Northrend, Pandaria, and Draenor, once you have gained access to a zone, you can go back to it at any point in time to experience scaled leveling as long as you have Chromie Time enabled.

If you choose to level outside of Chromie Time, zones have a level cap. This means that the mobs in zones will start and stop scaling at specific levels.

If you want a higher-level player to run you through dungeons and raids, or you want to manually enter instances, you will need to speak to Chromie to return to the present. If this is not done, you will not be able to manually enter instances.

Experience Boosts

Enrôlé - Starting at level 20, players can turn on War Mode in their faction's capital city. While war mode does flag the player for PvP, it also passively increases their experience gains. The baseline for this buff is 10% with the strength of the XP bonus increasing depending on how underrepresented your faction is.

Breuvage des dix terres - Players who have characters that are level 50+ can obtain these xp potions for their alts. These potions are purchased for Médaille de service de la Brigade de l’Honneur/Médaille de service de la 7e Légion from Approvisionneuse Mukra and Approvisionneur Forgebrune. These potions not only give a minor boost to primary stats, they also persist through death.

Holidays - Throughout the year, various holidays provide buffs that allow players to obtain increased XP gains. These holidays include Sanssaint, Fête du Feu du solstice d'été, and Anniversaire de WoW.

WOUHOU ! - This buff can be obtained from riding the carousel when the Foire de Sombrelune comes to town each month. However, be warned that this buff does not persist through death.

Haut-de-forme de Sombrelune - An alternative to the WOUHOU ! buff, this item gives the same effects as riding the carousel, except that you do not have to return to the faire to reapply the buff. The drawback of this item, however, is that you need to do the faire dailies to obtain multiple or purchase them using Bon(s) pour un prix de Sombrelune. However, these items DO NOT stack with WOUHOU !.

As the driver, maneuver the vehicle, destroy the three rows of pillars leading to the boss room, and spam Pyrite bleue at the boss during the encounter.

As the passenger, shoot down flying Pyrite liquide with Fusée antiaérienne, use Saisir la caisse to grab pyrite and refuel your demolisher, and give your demolisher a speed boost with Vitesse augmentée to escape from the boss when it fixates on your vehicle with Poursuivi.

Salvaged Siege Engine

Use Bélier to destroy the three rows of pillars leading up to the boss.

Interrupt the boss with Electro-choc when it casts Décharges de flammes.

Salvaged ChopperGardien du savoir de NorgannonColosse d'UlduarAbilities

Bélier ravageur - Deals massive physical damage and knocks the target away (if possible).

Décharges de flammes - An AoE fire attack. This needs to be interrupted by siege engines.

Barrage de projectiles - Deals very minor damage to a vehicle.

Poursuivi - A fixate that randomly targets one vehicle (usually prioritizes demolishers).

Strategy

Demolisher drivers spam Pyrite bleue (2 key) at the boss and make sure the debuff does not fall off. You want to maintain 10 stacks of the debuff at all times. Only move from the boss when targeted with Poursuivi. Move towards Pyrite liquide when your pyrite gets low (blue bar on your vehicle frame).

Demolisher passengers spam Fusée antiaérienne to knock down Pyrite liquide, use Saisir la caisse to grab pyrite and refuel your demolisher.

Siege engines interrupt the boss when it casts Décharges de flammes.

XT-002 DeconstructorAbilities

Bombe à gravité - One of two abilities that XT puts on a random player (including tanks). Detonates after 9 seconds and pulls nearby players towards the detonation.

Lumière incendiaire - One of two abilities that XT puts on a random player. Pulses an AoE for 9 seconds that deals holy damage to all players within 10 yards.

Colère assourdissante - A periodic AoE ability channeled by the boss that deals 10% of the afflicted player's maximum health in physical damage per second for 8 seconds. This ability cannot be outranged.

NPC's

Cœur du déconstructeur - This is dropped underneath wherever the boss is currently standing each time the boss loses 25% health. Any damage dealt to the heart while it is exposed deals damage to the boss. Killing the heart activates the boss's hard mode (and should be avoided).

Robot-boum XE-321 - One of three types of mobs summoned during each heart phase. Explodes on death, dealing damage to nearby players and robots.

Roueur XM-024 - Only one of these spawns per heart phase. A tank needs to pick this up.

Robot-ferrailleur XS-013 - A little robot that slowly walks towards the boss. If the robot reaches XT, it is absorbed and heals the boss for 1% of its maximum health.

XT StrategyPhase 1

Before the pull, place a marker near each of the 4 trash piles (each corner of the room).

Get the boss's health to each 25% threshold as quickly as possible.

Move away from the raid with Bombe à gravité or Lumière incendiaire. You do not need to run far away. Just move 15-20 yards away from others.

Make sure each player is in range of a healer for Colère assourdissante. Since healers at level 30 no longer have raid-wide CDs, players will need to heal themselves (if possible), and healers will need to focus on classes that cannot heal themselves.

Phase 2

Three waves of robots spawn per heart phase.

Add priority: Boombots > Scrapbots > Pummeller

Hero/Lust towards the end of the third heart phase.

Ranged DPS swap to the adds that spawn from the trash piles.

Melee damage the heart until roughly 20-30%, then swap to adds. Move away from boombots when they are about to die.

The off tank should pick up any pummellers that spawn. At the end of each phase 2, bring the pummeller(s) to the boss for cleave if they are still alive.

Algalon the ObserverAbilities

Ascension aux cieux - Algalon's enrage mechanic. He will cast this ability 6 minutes into the encounter or if AT LEAST one player does not soak Big Bang.

Big Bang - Deals massive physical damage to anyone not phased by a Trou noir and will remove players from the black hole phase. When this ability begins to be cast, all players (minus the tank currently tanking Algalon) should enter a Trou noir to avoid taking damage. The tank that stays out must use a large cool-down, such as Mur protecteur, to avoid dying. If the tank dies from Big Bang and no one else is unphased to deal with this mechanic, Algalon will cast Ascension aux cieux and wipe the raid.

Choc cosmique - One of the most common abilities that kills players learning the fight, Choc cosmique spawns a red, smoky/cylindrical object on the ground which detonates after a few seconds. Players who fail to move away from this ability will take a large amount of fire damage and also be knocked into the air, causing them to take significant fall damage upon landing. If a player gets knocked into the air, this ability can be countered with an immunity, such as Bouclier divin, Chute lente, or a teleport such as Transcendance : Transfert. This ability will also deal fire damage to the entire raid.

Coup de poing phasique - Periodically, Algalon will place this debuff on the tanks. If a tank reaches five stacks of Coup de poing phasique, they will become phased from the rest of the raid for 10 seconds. Tanks should taunt at 4 stacks of this debuff.

Coup de poing phasique - When a player (most likely the tank) reaches 5 stacks of Coup de poing phasique, they will become phased for 10 seconds. The best way to prevent this debuff is for the tanks to swap at 4 stacks of Coup de poing phasique.

Frappe quantique - Algalon's default attack. This ability hits the current tank for significant physical damage.

NPCs

Trou noir - These are created when a Effondrement d'étoile dies and explodes. Players who enter a Black Hole become phased and must deal with Matière noire while inside. Black Holes can be removed by kiting a Constellation vivante through it.

Effondrement d'étoile - These adds only spawn during Phase 1, lose 1% of their maximum health every second, and cast Explosion de trou noir when they die, which inflicts massive shadow damage to the entire raid. When a Effondrement d'étoile dies, it spawns a Trou noir.

Matière noire - Exists in the phase from entering a Trou noir and also periodically spawn from Trou noir in Phase 2 of the encounter.

Constellation vivante - These adds only spawn during Phase 1, spawn in groups of 3, and attack players with Barrage des Arcanes, which deals light arcane damage. These adds can either be ignored, passively cleaved down, or they can be kited through Trou noir which will remove both the constellation and the Black Hole.

Suggested Compositions10 Player:15 Player:25+ Player:Phase 1

After the RP ends, have a raid member use Tambours de rage (or equivalent) and begin nuking the boss. If DPS feels low, you can opt to save drums for after the first Big Bang.

The main tank will tank Algalon where he stands (only moving the boss if a Effondrement d'étoile comes too close to melee to avoid accidental cleave) until they reach 2 stacks of Coup de poing phasique. The Off-Tank will then taunt and hold the boss until after the first Big Bang is over.

When the Effondrement d'étoiles come out, a player (possibly 2 players in comps larger than 18 players) needs to begin killing one star at a time around Algalon. When the stars die, they will deal massive AoE damage to the entire raid. While the first explosion isn't particularly lethal (because everyone will most likely be topped and there’s not much else going on), the person killing stars will need to make sure the raid is close to topped before killing any more stars.

Avoid being knocked into the air by Choc cosmique and reduce damage taken by moving away (The raid leader should make regular callouts to help players avoid this mechanic).

(Optional) Kite or have Death Knights in your group grip Constellation vivante through Trou noir to close them.

When Algalon begins channeling Big Bang, all players except for the tank that is currently tanking Algalon need to run into a Trou noir to avoid being one-shot (sometimes they don't automatically phase you, so you may need to strafe inside them to become phased). The Tank staying out needs to pop a big cool down, and a healer may need to use an external cool down, such as Cocon de vie, to keep them alive. The Tank that goes in with the rest of the group needs to pick up the Matière noire so that they don’t kill the DPS and healers. Once Algalon finishes casting Big Bang, players will then be ported out back into the room.

If you didn't already use Tambours de rage on pull, use it after Big Bang ends and ignore the Effondrement d'étoile unless they are close to dying and you're not going to reach 20% before one dies.

Phase 2Trou noirEffondrement d'étoileConstellation vivanteBig BangChoc cosmiqueMatière noireTrou noirSuggested Compositions10 Player:15 Player:Overview

As soon as the RP ends, immediately use Tambours de rage (or an equivalent) and begin nuking the boss.

Everyone (including the healer when able) should do as much damage to Algalon as possible to get him to 20% before ANY collapsing stars die.

Ignore the constellations when they spawn (if possible), otherwise try and have the tank get aggro on them.

Once Algalon reaches 20%, he will put down 4 black holes on the ground.

Run/misdirect adds from the black holes to the tank if desired, otherwise continue to burn him until the fight ends.

Really nice guide, simple and great explanation. Thank you all!

I remember when we were trying to kill Algalon with ToC 25 heroic gear and still having a hard time. The fight was visually excellent.

Commentaire de Swordart21

Will still look down on guys with this title who did not achieved it during wotlk.

Commentaire de Dorave

"ALL Allied Races can be monks as well."

This is false. Lightforged Draenei cannot be monks.

Commentaire de theburningtundra

In the Gearing guide, Feral Druid does not have a shoulder listed.

Commentaire de Marsieh

As of BfA the Ilvl requirment is now <= 100. So you can now use all raids except icc25h and ruby sanctum 10h/25n/h for gearing. Everything else seems to drop ilvl100 max.

Commentaire de MatiSali23

Hi! First of all, good guide!

I have a question: Are we allowed to put BfA gems on our gear? Since now the requirement to link them is to have 100 item lv, Could it be possible?

Commentaire de tralum

Hey mate
First off i enjoyed your generall guide a lot and am currently trying to get the AV, so i appreciate the work you put into all these guides a lot.
BUUUUT ( yeah i know this had to come now :D) i have several rather specific suggestions that all come from the same 2 generall ones:
a) Normal mode Burning Crusade dungeon-gear, when farmed by a level 80 is in quite some cases supperior to level 80 raid gear.
Some examples are:
Shaarde the Lesser- weapon from Auchenai Crypts
as well as the Gauntlets of Divine Blessings from Magisters' Terrace
and the Girdle of the Immovable from The Slave Pens.
So as you can see there are quite a lot.
b) Proccing items (trinkets and weapons) dont seem to have an internal cooldown anymore, so quite a few of them have almost 100% uptime, which makes them in almost all cases supperior to active trinkets, which DO have their normal cooldown. (Sadly this issue does NOT seem to be shared by the ICC-faction rings.)
This is true for the tank weapon from icc "last word" (which still isnt particulaly good) and healing trinkets such as pandoras plea from mimiron, which, im fairly certain, makes it BiS for every heal class as it just gives a flat 91 int (i also think that the eye of the broodmother slipped past you for the heal shaman guide, but thats a side note)
(sorry for the double post I just really wanted to make sure you see this)

Commentaire de Sarkli

Good guide. My guild is using this as a base for knocking out the Feats of Strength soon. One thing i noticed that isnt mentioned, on the few caster guide i clicked on, is under consumables Superior Wizard Oil is not mentioned. It should be. It CAN BE APPLIED to a weapon in addition to your regular enchant. Also to note that at BFA level 80 it provides 32 intellect and the Cata flasks were able to use provide 34 intellect. Its basically giving you 2 flasks by using it.

Side note: I know sharpening stones used to work the same way in that they dont overwrite your weapon enchant. That being said i know there are some pretty decent ones out there that may work in a similar way for melee giving a bit of extra oomph to them as well.

Commentaire de DarkPhoenix666

Is the gear sheet up-to-date because some of the items listed for beast mastery are 105+ in the game.

Commentaire de achrystie

I went to the gear guide for priest and it has Evoker's Helmet of Second Sight, from a quest in BC as the helm slot.
It lists this item as ilvl 100, but if you do this quest at level 80, the ilvl is 105...was there some information somewhere that I was supposed to do this at 79 or something? What a waste of time. What item do I use now that I can't use this one?

Commentaire de nykion

Thank you very much! BFA changed a lot of content, glad to see content like this!

Commentaire de BeornwulfSaxon

I'd be really interested in seeing some thoughts on professions - i'm currently leveling a warrior for this and she's an engineer at the moment for filling out some other things, but i'd be interested to see what professions have what to offer here.

Commentaire de Serixon

Can anyone confirm whether or not this guide is updated for patch 8.2.5?

Commentaire de Albn

I'd say u guys got most of it down to earth except the tier list, alot of the downgrade classes at c and b are popping off but is greatly dependent on both playstyle and gear choosing.

Me myself i got both a Unh dk and a Affi lock, both are popping off at 2k dps (Unh) and 2.8k+ (affi). Most of them are just BIg build ups for the dps, just that u need to put in time to perfect it, so wouldn't put them at C tier when u put fury warriors at S that i've never seen break 2k dps in any group.

Just my opinion, great on the explaniation of the fight tho.

Commentaire de afaliwan

Hey Vills,

first of all great guide! I just wanted to mention few things:

I discovered that Resto-Druid is one of the S-Tier DPS Specs, with a huge lead to other S-Tier Specs. I was messing around on it a bit and thought I give it a try as a valid DPS-Spec and due to the scaling with Affinité farouche and Spellpower it's just super OP atm. I am doing between 2.3k-2.7k DPS on Herald. I have uploaded a PoV to YouTube, if you want to check that out for proof since this might sound very strange. Link: https://www.youtube.com/watch?v=MSB_XKhQn9M

Also, I personally would put Disc as a S-Tier healing spec, because of their massive DPS in the BL Phase and Barrier being such a good raid cooldown for cleaving living consellations.
Having atleast two of them in a small group is just nice.

Anyway great guide again, Cheers.

Commentaire de Nerilyn

Can anyone tell me if I can save the lock on bosses killed by a raid of characters 80 to make the achievement in a second group, or will bug too?

Commentaire de darthmogrin

why gems in this guide are all from BC? What is wrong with Pierre d'effroi souveraine and other WotLK gems lor example?

Commentaire de Nuclalex

Hello everyone !
A quick question about the raid, is it possible to kill the 2 first bosses during one raid and come back the next day for Algalon, maybe with some other players ? In both raid groups, players will be level 80.

Many thanks in advance for your answer !

PS: If you would like to do this before the prepatch, please contact me as we'll attempt it next week.

Commentaire de cheinii

does party sync work :?

(guess the answer is no ofc, but juuust to be sure)

Commentaire de Adrrianpor

Erm, how do you do this achievement post squish when ALL the healers are missing their AOE heals?

Commentaire de Nicolfo

Is there any chance of updating this guide with some bis for the demon hunter (tank and dps)+shadowland update?

Commentaire de JustNicolas

If you want to farm items at lvl 77 (outdated guide) you need to lvl up until you are 29 and then farm the items. My character was 77 and got squished to 29. The items were stil iLvL 34 which is all good.

Commentaire de AerosDarking

Is this achievement still possible since Shadowlands came out? A lot of class buffs and key abilities are missing at level 30, like warlock soulwells and warrior group damage buffs. I'm debating leveling up my Herald alt since the meta has probably changed since 8.3.
I kept the alt at level 30 with the correct gear to help any guild members that missed the first achievement run we did (and so I didn't have to grind out all that gear again).

Commentaire de Wangey

Any chance we could get an update to the guide for 10.0 and DF, both tier list for talents/strength of classes but also any gearing changes that came along with it.

Thank you so much for all the work you've already done keeping this up to date!

Commentaire de SeriesSix

For TWW - worth looking here for how to gear up now that the totem, ooze and other cheese items are nerfed.

Thanks to Unmendable from XPOff for writing that post or I would have just levels to 30 and borked everything.

Essentially
- level to level 23 then lock xp for ilvl107 gear to drop from Timewalking dungeons and spam them to gear up.
- level to 24 then lock again - ilvl 106 world quest and rarespawn loot from the Dragon Isles {eg trinkets).
- Level locking at 25; you can get a full set of ilvl 107 gear from normal dragonflight dungeons through chromie time. This includes necklaces that can be triple socketed. This loot will be ilvl 95 at 23.
- Level Lock 26; the 20th anniversary event vendor "Bobadormu" sells gear, especially mastery gear and weapons at ilvl 107.

There is also a discord - Discord link: https://discord.gg/UquEgHC9xS

Unmenable notes - When Level Locked at 24 you can attempt to solo or get carried by level 10/11/20/30 twinks or que up in chromie time burning crusade/wotlk dungeons for socketed 106 loot. This method can also be used to get 106 Balefire Branch from BFA or 106 Infinitely divisible Ooze from Shadowlands, or even 106 Parjesh's Medallion from Legion. At level 23 this loot is ilvl 100.
