Phase 1 (100% - 60%)

MechanicTypeDescription
Double Frontal CleaveCleaveTwo-hit combo shared between both tanks - double tank recommended
Nerve GasAoECovers 1/3 of arena with damaging ground effect + Vulnerability Down
Secondary HeadTankbusterTank swap required - debuffed tank dies instantly from primary head
BarofieldAoEAt 90% HP - dangerous field around Kaliya preventing passage

Nerve Gas Strategy:

  • Always occurs in sets of 3
  • After the third cast, expect the frontal cleave
  • Avoid standing in the affected areas

Secondary Head Strategy:

  • Tank swap mechanic
  • Off-tank should Provoke during the cast
  • Debuffed tank will die instantly if hit by primary head attack

Stack and Split Missiles

MechanicTypeDescription

Egg ConstructAddsKill before phase ends

Add Phase Strategy:

  • Phase lasts approximately 2 minutes 30 seconds regardless of progress
  • Kill Ball and Cube at roughly the same time
  • Kill Egg before phase ends
  • Keep all three shapes separated - don’t let them near each other
  • Prepare for massive AoE damage during phase transition

Phase 3 - Final Phase (~30%)

MechanicTypeDescription
Construct DetonationRaidwideThree constructs detonate at phase start
Nerve CloudRaidwideMassive raid-wide damage following detonation
Nanospore JetsSpreadTether mechanic pairing characters together

Nanospore Jets (Tethers) Strategy:

  • Pairs of characters get tethered together
  • Too far apart = Vulnerability Up
  • Separated further = instant death for both
  • If one tethered character dies, partner dies automatically
  • Crossing paths with other tethered pairs = Vulnerability Up stacks for all

Notes:

  • Double tank strategy recommended for frontal cleaves
  • Mitigate heavily during phase transitions
  • Tethered pairs must move carefully to avoid crossing
  • Nerve Gas and seed mechanics continue throughout Phase 3
