T2 – ADS Guide | FFXIV Binding Coil of Bahamut Turn 2

Encounter Overview

T2 – ADS is the second encounter of The Binding Coil of Bahamut and functions as a gauntlet-style raid. Instead of a single boss fight, players must progress through multiple ADS-type nodes while a strict timer counts down. The goal is to defeat all nodes and the final ADS before the timer expires, or the raid will be wiped.

This encounter introduces routing decisions and mechanic management. Each node defeated removes one mechanic from the final boss, while also empowering remaining enemies with buffs. Choosing which path to take and which mechanics to eliminate is a key part of the strategy.

Arena Overview

The arena is divided into multiple pathways leading to different nodes. Players must choose a route, defeating nodes along the way before reaching the final ADS. Each node introduces unique mechanics, and the order in which they are defeated directly impacts the difficulty of the final boss.

The encounter is governed by a timer represented by audible “clicks.” If the timer expires before all enemies are defeated, the raid is wiped.

Boss Mechanics

Global Mechanics (All Nodes + Final ADS)

High Voltage: Raid-wide damage that applies Paralysis, which periodically stuns players. This must be interrupted consistently.

Repelling Cannon: Point-blank AoE around the boss. Melee players should step out when this is cast.

Cleave: Frontal cone attack that applies Vulnerability Up. Tanks should swap around 3–4 stacks.

Node Mechanics

Monitoring Node:

• Vacuum Wave: Light raid-wide damage. Manageable, but becomes more dangerous when repeated.
• On Death: Remaining enemies gain Physical Damage Up.

Defense Node:

• Chain Lightning: Hits a player and chains to nearby players. Spread out to reduce damage overlap.
• On Death: Remaining enemies gain Slashing Resistance.

Disposal Node:

• Firestream: Star-shaped AoE pattern with multiple lines. Avoid all lines to prevent heavy damage and DoT.
• On Death: Remaining enemies gain Magic Resistance.

Quarantine Node:

• Allagan Rot: A debuff that must be passed between players before it expires. If it times out, it explodes and wipes the raid. Passing applies temporary immunity, so players must rotate carefully.
• On Death: Remaining enemies gain Haste, increasing attack speed.

Attack Node:

• Gravity Field: Places a damaging slow field on the ground. Avoid standing in it.
• On Death: Remaining enemies gain Blunt Resistance.

Sanitary Node:

• Ballast: Expanding ring AoEs that knock players back. Safe zone is behind the boss or outside the rings.
• On Death: Remaining enemies gain Piercing Resistance.

Final ADS

The final ADS uses all global mechanics and inherits abilities from any nodes that were not defeated during the gauntlet.

Mechanic Scaling:

• If Quarantine Node was not killed, ADS gains Allagan Rot at 75% HP.
• If Quarantine Node was killed, ADS instead gains either Gravity Field or Firestream at 75% HP.
• At 50% HP, ADS gains either Ballast or Chain Lightning, depending on remaining nodes.
• Additional mechanics may appear at 25% HP if multiple nodes were skipped.

Vacuum Wave (Enhanced): Returns during the final fight with significantly higher damage output, requiring consistent healing and mitigation.

Encounter Flow

Gauntlet Start: Engaging the first node begins the timer. The party must move quickly while maintaining control of mechanics.

Path Selection: Choose which nodes to defeat based on which mechanics you want to remove from the final boss. Prioritize removing mechanics your group struggles with.

Node Clearing: Defeat nodes while managing their mechanics and handling the buffs applied to remaining enemies.

Final Boss: Engage ADS with a reduced or modified mechanic set based on earlier decisions. Handle remaining mechanics while maintaining interrupts and tank swaps.

Enrage Condition: If the timer expires at any point, the raid is wiped.
