— In-game description
The Final Coil of Bahamut - Turn 4 is a level 50 raid introduced in patch 2.4. The raid is also known as T13.
It was first defeated by the Free Company Lucrezia on the server Alexander on November 2nd, 2014.
Objective
- Defeat Bahamut Prime.
Strategy
Bahamut Prime uses a simple arsenal of incredibly hard hitting attacks, requiring the group to learn and adapt or be flattened by his might. This fight has a hard 14 minute enrage.
Prior to the fight:
A marker should be placed as a location for players marked by Megaflare to stack.
Phase 1: 100% - 76%
To begin the fight players should pull the boss to the south wall of the arena. The walls will kill players on touch, so individuals must watch their footing.
| Name | Description |
|---|---|
| Flare Breath | A high damage cleave. |
| Flatten | An extremely powerful tankbuster. |
| Megaflare | Places Static circle AoEs under 3-4 players, hits 3-4 players with unmarked spread circles, and 2-4 players are targeted by rings of crystals. Players targeted by a ring of crystals can only survive by sharing their damage with another player marked by a ring.
|
| Earth Shaker | Two players are marked with brown spread line arrows. Bahamut Prime fires at both players three times, dropping a puddle under the targets with each attack that deals damage and inflicts  Heavy.
|
Much of this phase will be a trial for the healers, as every attack will deal incredible amounts of damage to either the main tank or the party.
Megaflare must be handled by having the entire party spread apart once the cast begins. Once the unavoidable explosions occur, those marked with rings of crystals can stack together in the pre-designated spot away from others.
Earthshaker will require the two marked players to split to the left and right side of the boss, and should aim to place the puddles against the edge of the arena. The rest of the party should stay safely behind Bahamut Prime.
Lastly, the Flatten and Flare Breath x3 combo can be handled by either using large mitigations or tank invulnerabilities. Due to the length of this fight, an invulnerability used in phase 1 is likely to be off cooldown by the time the final phase begins.
| Attack | Strategy |
|---|---|
| Flare Breath | Ensure the main tank's health stays topped up. |
| Megaflare | Spread out prior. Once players are marked with rings of crystal, those marked players should stack together in the designated spot. |
| Flare Breath | |
| Flatten | Tanks should use heavy mitigations or an invulnerability. A tank swap can be used afterwards to split mitigation cooldowns. |
| Flare Breath x3 | -- |
| Earth Shaker | The two marked players should split off to the left and right and run towards the edge of the arena, placing the puddles safely along the sides. |
| Repeat | |
This phase will repeat until the boss reaches 76% HP. Players should push this phase as hard as possible to give more time later to handle other phases.
It is also recommended that players use a DPS Limit Break level 1 to push the phase as a Tank Limit Break 3 will be needed later.
Phase 2: 76% - 52%
| Name | Description |
|---|---|
| Gigaflare | High unavoidable party-wide damage. |
| Shadow of Meracydia | An enemy that will tether to Bahamut Prime if too close, buffing each other. Additionally will fire lines of several puddles if left alive too long.
|
| Flare Star | Seven orbs will appear periodically and attach chase tethers to random players. Orbs move slowly at first, but speed up after 10 seconds. Touching an orb makes it explode into a small AoE, inflicting nearby players with a stack of  Suffocated Will.
|
| Rage of Bahamut | Unavoidable party wide damage that deals more damage to individuals based on their stacks of Suffocated Will. Clears all stacks afterwards.
|
| Flatten | Hits harder, but is no longer followed by three Flare Breaths. |
| Megaflare | Now also places a tower under a random player after the Static circle AoEs explode. |
While the second verse is similar to the first, the Shadow of Meracydia and Flare Star will require the entire party to shift focus away from Bahamut Prime temporarily to prevent unnecessary deaths.
The first Shadow of Meracydia always spawns in the north, which the off-tank can simply grab and hold still while the DPS kill it. Later spawns will be in the Southeast and Southwest and must be pulled away from Bahamut Prime immediately.
Players should attempt to distribute Flare Stars so that each member of the raid, minus the main tank, only gets one stack of Suffocated Will.
And lastly, the party should keep an eye out for the tower that appears during Megaflare. Players not marked by a ring of crystals should be prepared to hold their position should the tower appear under them, or run to the tower if left unoccupied.
| Attack | Strategy |
|---|---|
| Gigaflare / Rage of Bahamut | High amounts of party healing required. |
| Shadow of Meracydia | The off-tank should hold the enemy away from Bahamut Prime while DPS kill it as fast as possible. |
| Flare Star | Try to spread out stacks of Suffocated Will equally across the party. Non-tanks are unlikely to survive more than 2 stacks.
|
| Flare Breath | Prepare for heavy healing on the main tank. |
| Flatten | Mitigate and heal. |
| Flare Breath | -- |
| Megaflare | Spread out as before. Be aware that a tower will now spawn under one random player. This tower must be occupied by a player or it will explode and wipe the raid. |
| Flare Breath | -- |
| Repeat | |
This phase repeats until 52% HP, after which Bahamut Prime will cast another Gigaflare and leave the arena.
Phase 3: Dragons of Meracydia
| Name | Description |
|---|---|
| Divebomb | Bahamut Prime appears in a random position outside the arena and places a red circle above a player, then a Storm of Meracydia appears in another location and places a green circle above a different player.
Both dragons dive at the locations the markers were initially placed, dealing high damage and knockback in a line AoE. At the same time, Megaflare is cast. |
| The Blood of Meracydia | A dragon with low health, but is shielded by either a  Physical Damage Shield or a  Magical Damage Shield. The type of shield it has swaps frequently.
|
| The Pain of Meracydia | A hard-hitting bipedal dragon that attacks with cleaves from its front and back. Absorbs nearby Gusts of Meracydia, restoring health and gaining  Damage Up.
|
| The Gust of Meracydia | Small whelps that spawn in groups. Has no outstanding abilities. |
| The Sin of Meracydia | Large blue dragons that hit moderately hard. After 20 seconds, casts Evil Eye, dealing damage equal to their remaining health to the party. |
| The Storm of Meracydia | A large flying wyvern reminiscent of Twintania. Similarly attacks with Death Sentence, a moderate damage tankbuster. Drops a Neurolink 2.0 puddle on the ground on death, which grants  Flare Dampening while inside.
|
| Teraflare | Bahamut Prime's ultimate attack. Can only be survived by standing inside the Neurolink 2.0 puddle and using a Tank Limit Break 3 at the same time. |
An intermission phase, the deadliest attack players will have to contend against will be Divebomb.
It is recommended for the entire party to stack up in the center as there is no way to predict which direction Bahamut Prime or The Storm will appear from. By grouping in the center until both targeting icons appear, both are guaranteed to fly straight across the arena.
Players will have to react quickly to the locations of both Bahamut Prime and The Storm and run towards the edges out of the path of both. At the same time, players will have to spread out for Megaflare before letting the ring-marked players stack back up in the center.
Between Divebombs, waves of enemies spawn that all must be handled differently:
- Blood of Meracydia should be killed first due to its low amount of health.
- Pain of Meracydia must be faced 90 degrees away from the party to protect them from the claws and tail.
- Sins of Meracydia are of the highest priority and must be DPS to low HP as quickly as possible. A cast of Evil Eye at high health will likely wipe the party.
- Gusts of Meracydia can be ignored by most of the party until last, only needing to be kept away from The Pain of Meracydia.
- Storm of Meracydia can be treated akin to any other boss.
One all enemies are defeat and Bahamut Prime casts their final divebomb alone, a long cast of Teraflare will begin. All players must run into the Neurolink 2.0, and a tank must use their Limit Break after the countdown reaches 4 seconds remaining.
| Attack | Strategy |
|---|---|
| Divebomb + Megaflare | Stack in the center until both markers appear, the move away from danger while spreading out for Megaflare. |
| Blood + Pain of Meracydia | Kill the Blood of Meracydia first, then The Pain. |
| Gust of Meracydia x3 | Have the available tank pick up The Gusts and moved away from The Pain if necessary. These can be ignored until later if other enemies are still alive. |
| Sin of Meracydia x2 | DPS both Sins to as low as possible before they can cast Evil Eye. |
| Divebomb + Megaflare | Handle as before. |
| Storm of Meracydia | Tank and begin DPSing them down. |
| Blood of Meracydia | Switch targets and kill The Blood. |
| Gust of Meracydia x2 | The tank holding enmity on The Storm can also pick up these enemies to ensure they stay away from other dragons. |
| Sin of Meracydia | DPS must focus The Sin and kill it as quickly as possible. |
| Pain of Meracydia | Kill both The Storm and The Pain and move back to center in preparation for the final Divebomb and Megaflare. |
| Divebomb (Bahamut Only) + Megaflare | Handle as before. |
| Teraflare | Group up in the Neurolink 2.0 and use a well timed Tank Limit Break 3 to reach the final phase. |
| Phase 4 Start | |
After the party survives Teraflare, Bahamut will return to the arena and begin the final phase.
Phase 4: 52% - 0%
| Name | Description |
|---|---|
| Akh Morn | A multi-hit shared tankbuster. Damage will be divided with the player closest to the main tank when the cast finishes. The first hit deals the highest damage, with every hit after dealing about half as much as the first.
|
| Tempest Wing | Attaches two transferable tethers to players. After a few seconds, the tethered players are hit with AoE tankbusters. Players too close to the tethered targets when they burst take heavy knockback and  Bleeding.
|
| Megaflare | Now spawns two towers, and is always paired with Tempest Wing. |
| Earthshaker | Now tethers the same two marked players with Tempest Wing. |
Damage output during this phase is extremely high, taxing the healers to their limits. Tanks have to utilize their mitigations as much as possible to lighten the burden on healers.
Akh Morn must be shared between both tanks. When the cast starts, the off-tank should run to and stack with the main tank to share the damage. By the third cast, it is recommended to instead take the attack alone and use an invulnerability.
Tempest Wing creates even more tankbusters to worry about. Tanks will constantly need to be intercepting tethers placed on other party members and moving the attack safely away from the party. Standing too close to others is likely to outright kill them, if not send them flying into the wall of death.
After every second Earthshaker + Tempest Wing, Bahamut Prime will cast Gigaflare for massive party damage before repeating their rotation.
| Attack | Strategy |
|---|---|
| Akh Morn | Both tanks must stack together and mitigate. If this is the third cast, using an invulnerability to take the attack alone is recommended. |
| Megaflare + Tempest Wing | Tanks must intercept the tethers and move them away from the party while the rest spread out. Ensure players stay in towers that appear underneath them. |
| Earthshaker + Tempest Wing | Quickly grab the tethers off the players marked for Earthshaker and move away from the blast zones. Quickly heal the main tank up after this so they survive the next Flare Breath. |
| Flare Breath | Keep the main tank alive. |
| Akh Morn | Mitigate and heal. If this is the fourth cast, a tank swap prior to use another invulnerability is recommended. |
| Megaflare + Tempest Wing | Repeat as before. |
| Earthshaker + Tempest Wing | Repeat as before. |
| Flare Breath | Repeat as before. |
| Gigaflare | Use party mitigations and heal through the flames. |
| Repeat | |
This repeats until the boss is either defeated or enrages. At its enrage, it casts a 15-second Gigaflare that will wipe the party.
Solo strategy
As of patch 6.0, the duty can be easily cleared solo by any well-geared level 90 character.
The boss fight consists of attacking the boss and the adds it spawns until they die. The only danger lies in the three phases in which the boss and its add charge through the arena; they must be carefully evaded or they will push the player out of the arena and to their death.
