The Binding Coil of Bahamut - Turn 1

The Binding Coil of Bahamut - Turn 1, located in the Upper Aetheroacoustic Exploratory Site and known by players as T1, is the first turn of the Binding Coil of Bahamut in Final Fantasy XIV: A Realm Reborn.
== Story ==
During the Battle of Carteneau, a fragment of Dalamud landed in Eastern La Noscea, creating a crystalline cave over which the XIVth Imperial Legion built Castrum Occidens. The Garlean Empire sent forces into the labyrinth in search of the Allagan technology encased within Dalamud.
Alisaie Leveilleur and the Scions of the Seventh Dawn send an expedition of their own into the coil, hoping to get to the Allagan weaponry before the Garleans can and unearth the truth behind the Seventh Umbral Era and the death of Louisoix Leveilleur. However, 237 yalms below the surface, they meet resistance from Allagan biotech that is still live, thousands of years after the fall of their Empire.

== Progression ==
=== Meteor fissure ===
After witnessing a cutscene, the party descends down a Garlean-built staircase into a side cave guarded by the ADS mid-boss. Throughout the fight, it will use High Voltage to paralyze the party, making it recommended to Silence the attack. During the battle, smaller Attack Nodes will appear from behind and should be dealt with by an off-tank. If not destroyed swiftly, ADS will begin casting Object199, dealing heavy damage to the raid.
=== Aetheroacoustic Exploratory Site ===
The party must venture through trash packs to clear the exploratory site. However, one cannot simply sac pull all of the enemies, because two Aetherial Fields are gated by the deaths of Dark Matter Golems which must be killed normally. The Dark Matter Golems have access to a powerful attack called Obliterate but are otherwise harmless.
=== Allagan Megastructure ===
The party fights Caduceus on this honeycomb-like structure.
Every 30 seconds, Caduceus will receive a stacking buff to damage and certain platforms on the floor of the Megastructure will glow blue. If a player stands on the glowing platforms, a Dark Matter Slime will spawn and aggro the player that spawned it. If the player runs away from the slime, it will detonate, dealing heavy damage to the party. In addition, if the slime is brought to Caduceus, it will donate its health to the boss and remove all of the buff stacks. Meanwhile, the boss will attack the tank and launch a Tail Swipe that will damage any melee fighters that don't dodge it. Caduceus will also attack random players with Acid Spit, which creates a puddle of acid under the target, dealing damage over time.
Once Caduceus reaches 60% health, it will split into two snakes with 30% health each. If the snakes are allowed to fuse together, the resulting Caduceus will begin to gain stacks every 3 seconds, and both bosses must be destroyed around the same time.
The intended strategy for use against Caduceus is to designate a non-tank to spawn a single Dark Matter Slime every time the boss gains a stack, and DPS it down to very low health before feeding it to the boss, removing its stacks. When the second Caduceus spawns, the off-tank must pull it away, and two players must be responsible for pulling two Dark Matter Slimes, one for each snake. Two DPS will attack each snake, timing their attacks so that both are slain at the same time.
However, with nerfs to the original Binding Coil, it has become more popular for parties to avoid spawning Dark Matter Slimes at all, and allow the snakes to fuse at 60%. The heavily-stacked Caduceus will deal heavy damage to the main tank, and the healers must be prepared for the barrage of attacks that the boss will launch. However, with only 302,079 HP, the boss should fall before the party is overrun.
