Bone Dragon

The first boss of the Labyrinth of the Ancients is the Bone Dragon. This boss appears in a large circular arena, withgreen platformssimilar to the area before. These areused in the same way, too.Stand on the green platforms throughout the fight to avoid the rising purple liquid.

The Bone Dragon itself doesn’t have a lot to it. After defeating it, it willresurrect itself a few times, but it doesn’t use any difficult attacks. However, throughout the fight,Platinalswill spawn and attack players.When these die, their bones will stay in placefor a few seconds beforeresurrecting and running toward the Bone Dragon. When they reach the boss, they willexplode, dealingdamage to all raid members.

When enough Platinals explode at the same time, you may take more damage than you can handle. To avoid this situation, some players shoulddrag the Platinals away from the Bone Dragon. This way, when they revive, you haveenough time to quickly kill them again before they reach the Bone Dragon, thus saving you from an explosion. This whole process willrepeat a few timesuntil the Bone Dragon is defeated for good.

Atomos

The second boss of the Labyrinth of the Ancients is a set ofthree Atomos. For this fight, you willsplit into three different lanesdepending on yourAlliance letter. AllianceA goes to the left, AllianceB to the middle, and AllianceC to the right.

Don’t start this fight until everyone is split and sorted correctly.

At first, Atomos will be protected by a barrier. To remove this barrier,at least four players need to stand on the panel near the entrance to the arena. However, when activated, this panel actuallydrops the barrier of a different Alliance’s Atomos. Because of this,all three Alliances need to work together to keep each team’s barrier down.

While four players are standing on the panel, the other four will attack Atomos. Typically,ranged characters should stay back on the panel, while melee players attack Atomos. Various enemies will spawn, but these have low health and can be downed in a few attacks.Focus on killing Atomos, then wait for the other Alliances to finish.Remember to stay on the panel until all Alliances have killed their Atomos.

Thanatos

The third boss of the Labyrinth of the Ancients is Thanatos. As this fight begins, one of thethree Magic Potsthat are positioned around the edges of the arena willgrant Alliance A the Astral Realignment buff. This buff reduces the amount of damage you deal, butenables you to hit ghostly enemies, like Thanatos. This buff will thenrotate to the other two Alliances after it expires.

The Alliance that has theAstral Realignment buff should focus entirely on damaging Thanatos, while members ofun-buffed Alliances should protect the Magic Potsfrom the various enemies that spawn. If all three Magic Pots are destroyed, the buff willno longer be applied, and you won’t be able to kill Thanatos.

There aren’t too many attacks to worry about here, so just remember the basics.If you have the buff, attack Thanatos. If you don’t have the buff, kill the adds. Simple!

Allagan Bomb

The Allagan Bomb is the fourth boss of the Labyrinth of the Ancients. This is anothersplit encounter, in which each Alliance will take on aVassagoenemy. The Tank of each Alliance shouldface this enemy toward the outer edge of the arenato avoid hitting other players with its large cleave attacks. The Vassago are tethered to the Allagan Bomb, making it immune to damage.

While you are fighting the Vassago, several enemies will spawn, such asAllagan BalloonsandNapalm. Kill these when they appear before returning your attention to the Vassago.

When all three Vassago have been killed, the Allagan Bomb will be vulnerable, and you can make quick work of it.

King Behemoth

The fifth boss of the Labyrinth of the Ancients is King Behemoth. Throughout the fight, several players will be targeted with agreen marker that drops a comet on their position, dealing damage. Then, Behemoth will useEcliptic Meteor, dealinglethal damage to all players. To avoid this,stand behind one of the cometsuntil the meteor explodes.

However, keep in mind thatIron Giant addswill be summoned throughout the fight. These enemies will attack with a large cleave that candamage and even destroy the comets. To prevent this,kill the Iron Giants before they destroy the cometyou are hiding behind.

Phlegethon

The final boss of the Labyrinth of the Ancients is Phlegethon. This boss has severalAoE attacksthat it will use throughout the fight, but they aretelegraphedand easy to dodge by moving out of the way.

At around50 percent remaining health, Phlegethon willmove to the center of the arenaand begin castingAncient Flare. This attack willinstantly kill every player. To avoid this, you will need tomove with your Alliance to one of the three panels positioned on the east, south, and west edges of the arena. When around seven players are standing on each panel, abarrier will activateand protect you from Ancient Flare.

When the barrier is up, an Iron Giant will spawn. Simply kill it to drop the barrier and get back into the fight.

Ancient Flare will be used again when Phlegethon has around 10 percent health remaining. Repeat the same process to create a barrier. Sometimes, if Phlegethon has low enough health, some players may opt toattempt to kill the boss before it finishes casting Ancient Flareinstead of activating the barrier. This is risky; if not enough players commit to this play, then everyone will wind up dead.Only take the chance if everyone is on board, or you are confident you have enough time to kill it.

With that, the Labyrinth of the Ancients is complete. Grab your loot on your way out, and don’t forget to commend another player!
