The Second Coil of Bahamut - Turn 3

Notice

All Lv. 50 Bahamut raids do not appear in any Duty Roulettes due to their high difficulty (comparable to Savage). Therefore, attempting to queue through Duty Finder will result in extremely long queues. For an easy completion, it is recommended that players use Party Finder and form an Unrestricted Party (i.e., with level sync disabled). Players who wish to complete this duty with level sync enabled should also form a pre-made party, which also enables the use of Minimum Item Level and Silence Echo settings for an additional challenge.

Your party activates the coil's lift-like mechanism, and, at a depth of 3256 yalms, arrives within the interior of the internment hulk proper. The great cavern where the elder primal Bahamut dreams is yet many thousands of yalms distant. Explore the labyrinthine passages of the Ragnarok-class starship, and secure a route into the lowest levels of the hulk.

— In-game description

The Second Coil of Bahamut - Turn 3 is a level 50 raid introduced in patch 2.2. The raid is also known as T8.

Objectives

Open the frontal bulkhead. 0/1
Defeat the Avatar. 0/1

Enemies

Travel south from the entrance to Sector XII in the Lower Decks. Use the jump pad to go up to Sector VII in the Main Decks. Go south to the Frontal Bulkhead and open it to reach The Avatar boss.

The Avatar

This fight has a 11m hard enrage timer after which The Avatar will wipe the party.

While the Avatar will progress phases if enough damage is done, time is also a factor and The Avatar will change phases based on their Biotower rotation.

The Avatar can not change phases if towers are active and charging. This can be used to skip phases entirely.

When attempting this duty solo, The Avatar will instantly kill the player with Ballistic Missile if allowed to reach Phase 2.
Players must force this phase to be skipped by bringing The Avatar to 45% health while towers are still charging in order to skip to phase 3. Players can bring The Avatar to 76% and wait for the second set of towers to spawn to create an easier DPS check.

Biotowers

The Avatar has four Biotowers, one located at the North, East, South, and West edges of the room. Towers appear in pre-determined sets of two or three based on time and/or phase.

Towers have a charge meter behind them, starting with one charge and instantly activating at five. Towers gain one charge every 15 seconds in Phase 1 and 2, and 20 seconds in Phase 3.

When towers charge themselves, if two towers hold an equal amount of charges The Avatar will gain a stack of Vulnerability Down and Damage Up. If three towers are equal, The Avatar will gain two stacks of each buff.

If two or more towers charge to maximum simultaneously, The Avatar will enrage and wipe the party with repeated casts of Atomic Ray. If the Avatar is forced to skip phases due to low health, this will also bypass the enrage.

Players can forcefully charge towers by standing in the adjacent electrified fields. This will grant one charge per player in the field as well as inflict those players with a stack of Languishing for 90 seconds.

Manually charging a tower costs health, the HP cost increased per stack of Languishing. The first charge deals 10%^[1] of max health, then 20%, 40%, 70%, and finally 120% of max health until the debuff expires.

There is a 20 second period between the last tower's natural activation (nobody running in to charge it) and when the next set of towers spawn. It's always 20 seconds, whether there are two or three towers.

During two tower phases, it is an 80 second cycle (4x15s between natural charges + 20s before next towers spawn). Languishing lasts 90 seconds, so you have to plan accordingly.

During three tower phases, it is a 100 seconds cycle (4x20s between natural charges + 20s before next towers spawn). Because it's longer than the 90s debuff, you can have the same people activate the towers.

Turn 8 Video Guide

Tower Descriptions
Visual	Location	Fully Charged Effect
	North	Summons one Clockwork Dreadnaught. This enemy hits very hard with frequent frontal cleave attacks.
	East	Creates 3 landmines in random areas. Mines become invisible a few seconds after creation. Touching a mine explodes it, inflicting knockback and ~2000 AoE damage. After 15 seconds, The Avatar will force-detonate all existing mines, wiping the party. Knockback can be resisted using Arm's Length or Surecast.
	South & West	Deals ~2500 damage to the entire party.

Phase 1: 100% - 75% or 2m40s

The Avatar's first phase is comprised of two sets of towers, but will skip to phase 2 early if brought to 75% before the second set of Biotowers appears.

This boss stays immobile in the center of the room. If the main enmity target moves too far away from The Avatar, it will attack with ranged lasers that hit much harder than its melee attack.

Phase 1 Abilities
Name	Description
Diffusion Ray	A frontal cleave that deals heavy damage and applies Bleeding. The debuff ticks for ~600 damage and can be cleansed with Esuna.
Gaseous Bomb	A stack marker indicated with a "satellite-like" laser. Damage will be divided across all players near the marked.
Homing Missile	A transferable tether from the boss to a non-tank player. The target explodes in a moderate AoE for ~1500 damage.

Fighting in the northeast corner of the boss (the back-left corner as you enter the room) is recommended because this gives you access to two important Biotowers, and gives easy vision of the AoE biotowers to the healers.

The Biotower rotation for Phase 1 is:

Set 1 (Dread + West Tower)

Set 2 (Mines + West Tower)

Phase 1 Rotation
Attack	Strategy
Diffusion Ray	Always face The Avatar away from the party. Healers should Esuna the Bleeding off the main tank whenever possible.
Biotowers	If Set 1, players should charge the Dreadnaught Tower and have the off-tank hold aggro. Ensure the enemy is faced away from the group and have DPS take it down fast. If Set 2, players should charge the Landmine tower. The off-tank should run into and detonate the mines, being careful not to get bounced into multiple mines at once. DPS can help detonate mines if careful.
Homing Missile	Have one player (preferably the off-tank) intercept the tether and run it away from the group.
Diffusion Ray
Gaseous Bomb	The group should stack behind The Avatar to spread out the damage equally.
Diffusion Ray x2
Homing Missile	Move the tether away from the group.
Gaseous Bomb	Stack behind the boss, staying away from whichever player is tethered.
Diffusion Ray
Repeat until Phase 2

Phase 2: 75% - 45% or 2m40s - 7m

The Avatar adds two new deadly attacks to its arsenal. It is possible to skip this phase entirely by bringing The Avatar to 45% health while the second set of towers is up in Phase 1.

Phase 2 Abilities
Name	Description
Brain Jack	Debuffs the main tank with Brain Jack, causing them to run to the nearest player and attack them for 10 seconds. This does not effect enmity. Cast every 30 seconds and is always followed by Diffusion Ray.
Ballistic Missile	A Multi-player Stack Marker. Binds two random players in place and marks them with a large or small circle. If an incorrect amount of players are in the circle, all inside are instantly killed. The small circle requires two players inside, while the large one requires three. The bound players are included in the count.

The most dangerous attack is Ballistic Missile and will require the majority of the groups attention and effort.

A common method to handle Ballistic Missile is to have to entire group stack together prior to the attack, having one player assigned to be the third for the stack if needed. As it is random which two players are chosen, three players may need to be assigned and given a priority order. As the two bound players will meet the requirements for the small circle, only one player will need to be present if there is a large circle, standing on the very edge as to not be inside the small circle if present.

The Biotower rotation for Phase 2 is:

Set 3 (Dread + West Tower)

Set 4 (Mines + West Tower)

Set 5 (Dread + Mines Tower)

Phase 2 Rotation
Phase	Attack	Strategy
Opening	Ballistic Missile	Ensure the correct amount of people are standing in the circle. Failure to handle this mechanic is likely to lead to a wipe.
Loop	Biotowers	If Set 3, rush the Dreadnaught tower, but be mindful of the Brain Jack that may occupy the off-tank. If Set 4, rush the Landmine tower. Likewise due to Brain Jack, DPS may want to aid in detonating mines. If Set 5, either tower is equally dangerous, but one must be chosen.
	Diffusion Ray
	Brain Jack	An simple method to trivialize this debuff is to have one player stand under The Avatar but just barely out of Diffusion Ray range. The main-tank will then attack that player without turning the boss. While an off-tank is an obvious choice for standing under The Avatar, they may be occupied with handling Biotowers. A magical DPS may be the best fit for this role. Alternatively, a tank-swap can occur instead, but both tanks will still be occupied until the Brain Jack expires.
	Diffusion Ray
	Homing Missile	Place the tether away from the group.
	Diffusion Ray
	Gaseous Bomb	Stack behind the boss.
	Brain Jack	Handle as before.
	Homing Missile	Place the tether away from the group.
	Diffusion Ray
	Ballistic Missile	Handle as before.
	Gaseous Bomb	Stack behind the boss.
	Repeat Twice from Biotowers

Phase 3: 45% to 0% or 7m - 11m

The Avatar loses the ability to use Ballistic Missile, but gains an equally dangerous new attack. Towers in this phase will now gain charges every 20 seconds instead of the previous 15.

Phase 3 Abilities
Name	Description
Allagan Field	A random non-tank is debuffed with Allagan Field. After the debuff expires, it deals party-wide damage equal to twice the damage that the debuffed player took over its duration. Shields from a Scholar or Sage will negate incoming damage, providing a safety net. After expiration, there is a 10 second safety window before Allagan Field is cast on another player. Homing Missile will always target the player debuffed with Allagan Field first.

This new attack will require the entire party's focus to deal with. The player debuffed with Allagan Field must intentionally avoid all mechanics and damage, as it can easily lead to a party wipe once the debuff expires.

AoE towers especially will need to be timed carefully to explode between Allagan Field casts.

Due to the charge timers on towers lining up with Allagan Field, players can prepare two towers to auto-activate the instant Allagan Field expires by giving one +3 charges and a different tower +1 charge.

Alternatively, players can wait until Allagan Field expires and manually rush the remaining AoE tower charges in the safe 10 second window.

The Biotower rotation for Phase 3 is:

Set 6 (Mines + West + South Tower): Send 3 players to West and 1 player to South. Ensure the Allagan Field player is safely away from any landmines once they appear.

Set 7 (Mines + Dread + South Tower): Send 2 players to the Dreadnaught tower and 1 player to South.

Set 8 (Mines + West + South Tower): Handle the same as Set 6.

Note: Biotower spawn timers do not line up equally with the rotation and thus have been omitted, but Biotower charge timers will always line up with Allagan Field timers. Towers spawn or gain a charge when Allagan Field is at 20 seconds and 0 seconds.

Phase 3 Rotation (Biotowers Omitted)
Attack	Strategy
Allagan Field	The player debuffed with Allagan Field should be marked and run away from the group to a far corner. This player should avoid all mechanics until the debuff expires. Keep this player shielded at all times.
Homing Missile	Will attempt to tether to the player with Allagan Field. Another player should immediately pick up this tether and move it away.
Diffusion Ray
Gaseous Bomb	All players except for the debuffed should stack together.
Diffusion Ray
Allagan Field	A new player will be debuffed and must separate far from the group. Keep shields on them at all times.
Diffusion Ray
Homing Missile	Grab this and move it away from the group and the Allagan Field player.
Gaseous Bomb	All other players stack.
Diffusion Ray x2
Loop Repeat

Dialogue

Cutscene

Alisaie: I am reminded of the passages beneath Castrum Occidens. We must have traveled quite some distance below the surface. 
Alisaie: More of the same tunnels... Twelve be good! Surely they cannot continue all the way down from the upper floors?
Alisaie: Tis difficult to see inside, but I have a terrible feeling those corridors house more of the dreadful guardians you have already faced. 
Alisaie: It is said that the Allagans excelled in the creation of chimerical beasts, and that the red moon teemed with a thousand thousand fantastical monstrosities─all to prevent the enemies of the ancient empire from releasing the elder primal. 
Alisaie: I wonder, the creatures that prowl these halls─could they be the “beloved children” of which Nael spoke? 
Alisaie: Well, this is yet another mystery to ponder upon our return. Shall we continue onwards?

↑ The first charge a player gives to a Biotower (before gaining a Languishing debuff) can have its damage reduced by defensive stats and abilities. Once players are inflicted with Languishing, defense is completely ignored.
