Boss 1: Rotar

Rotar kicks off the dungeon with mechanics that test precision and awareness. The fight revolves around shape matching and lantern management.

Shape Matching: Pay close attention to the icon beneath your character’s feet and stand on the geometric shape near the boss that matches it. Failing to do so can deal fatal damage instantly.

Lantern Control: Colored lanterns spawn throughout the fight. Players must destroy the ones linked to their assigned shapes quickly.

Purple Lanterns: These are especially dangerous and high-priority. Always focus on them immediately when they appear.

Success here relies on quick reactions and strict adherence to assigned shapes and colors. Teams that communicate clearly about lantern assignments often cruise through this phase.

Boss 2: Robstino

Robstino introduces interactive object management and requires heightened spatial awareness. This fight can quickly wipe the party if timing and positioning are off.

Mirror Reflections: Spinning mirrors create reflected images that indicate the correct action prompts.

Interaction Timing: Avoid standing in the mirror’s radius while it spins, or you’ll trigger a raid-wide AoE that disables healing and defensive skills. Step in only when the spin ends and hit the correct prompt.

Player Scaling: Later phases demand multiple players (up to three) to enter the same mirror and hit synchronized prompts. One mistake can fail the entire phase.

This encounter is a test of patience and observation. Teams that pre-plan roles for each mirror phase tend to have a smoother run.

Boss 3: Kromede's Desolation

The final boss fight against Kromede is a mix of precise positioning and high DPS pressure. Mistakes here are unforgiving.

Clone Lines: Certain players will be marked and targeted by boss clones that fire linear AoEs. Position these clones carefully, as their attacks leave rectangular puddles of damage lasting 30 seconds.

Truth Within the Mirror: At 75% health, Kromede teleports and spawns eight mirrors. Only one mirror is blank; the party must move there to avoid a devastating arena-wide blast. The safe mirror is always in one of the four corners relative to the main entrance.

The Heart Run: In her desperation phase, a strict 20-second window appears to navigate floating hearts, reach the boss, and break her shield. Pool all high-stagger or burst-damage skills during this period, or the raid risks an instant wipe.

This fight demands flawless teamwork and split-second execution. Communication and planning are just as important as raw damage output.
