The Binding Coil of Bahamut - Turn 1

A Realm Reborn Raid Lv50 iLvl 70

The first turn of the Binding Coil delves into the depths beneath Castrum Occidens, where adventurers encounter Caduceus, a massive two-headed snake guarding the way forward.

Caduceus

A unique boss fight centered around managing Steel Scales stacks and coordinating the split phase at 66% HP.

Phase 1 (100% - 66%)

MechanicTypeDescription
Hood SwingCleaveMassive frontal cone (160-180 degrees) - only tanks should be in front
Whip BackCleaveDevastating rear-facing AoE - do not stand behind the boss
Steel ScalesEnrageBoss gains a stack every ~45 seconds, increasing damage dealt
Glowing TilesAddsFloor tiles glow and spawn Dark Matter Slimes on players standing on them
Acid SpitAoESingle-target attack that leaves a damaging DoT pool on the ground

Dark Matter Slimes

When tiles glow, slimes spawn on any player standing on them:

  • Slimes fixate on whoever spawned them
  • If moved too far away, they explode dealing massive AoE damage
  • Lower slimes to under 20% HP before feeding them to Caduceus
  • Feeding slimes removes Steel Scales stacks from the boss

Phase 2 (66% - 0%)

At 66% HP, Caduceus splits into two separate snakes.

MechanicTypeDescription
SplitAddsBoss divides into two snakes, each retaining Steel Scales stacks
RecombinationEnrageIf the two halves get too close, they merge with combined stacks
Synchronized KillEnrageBoth halves must die within ~20 seconds or Caduceus respawns at full HP

Notes:

  • Organize into two teams (1 Tank, 1 Healer, 2 DPS each) for the split phase
  • Approach from the center/sides to avoid frontal and rear cleaves
  • Clear all Steel Scales stacks before the 66% split if possible
  • Keep the two snake halves separated but kill them within 20 seconds of each other
