Entry, difficulty & preparation

Assign colours, a rapid-hit spear breaker and a backup before entering. Stage 4 increases stagger-bar requirements in the reviewed setup.

Entry requirementsSelect this dungeon and difficulty in the entry panel. Check character level, item level, minimum party size and remaining entries there. The reviewed mechanic videos do not establish a current numeric admission threshold.
Before pullingAgree assignments, activate available checkpoints, clear pursuing enemies and prepare movement, defensive and stagger skills.

Siliator of Deceit

Agree the two crossing lanes before the pull. Do not have both targets run in the same direction.

Tell / phaseYour responseWhy it matters
Around 75%, two tracking chakramsThe two targets position so the blades cross near the centre and collide. Hold the planned positions until the collision.Moving early can prevent the collision and leave blades active.
Side lines before chakramsLeave the ends of the initial lanes.A blade can hit before the tracking portion is obvious.
Locked stagger bar and repeated circlesKeep moving as circles drop chakrams, then use gaps in the returning lines.Stopping to finish a cast adds unnecessary hits.
Furthest line / frontal then donutAvoid both outward and returning line hits; move inward after the frontal resolves.The return path and donut are separate checks.

Ruthilis of Pain

Keep moving with the room’s sequence rather than racing directly across lingering lightning.

Tell / phaseYour responseWhy it matters
Clockwise quadrant cleavesFollow the newly safe quadrant. Only three lightning sectors remain active; use the outer route when returning.The next sector is not safe until its old field disappears.
Four personal circlesSpread, then prepare to jump the delayed ring if you were hit.The delayed pulse can catch players after the visible circle ends.
Early furthest jump and donutBait the jump away from teammates, then respect the inner safe area.The jump is followed by a distance reversal.
Below about 50%, personal linesSeparate the lanes and leave them quickly.These hits add bleed and knockdown.

Talisra of the Void

Use the cast tell for the late colour phase: the source mentions both roughly 30% and 35%, so a precise guaranteed threshold is not asserted here.

Tell / phaseYour responseWhy it matters
Colour collection around 75% and again lateAssign purple and white collectors. Intercept only your colour for both waves, then spread personal domes.A wrong-colour pickup stuns and disrupts progress; nearby domes can disappear.
Crystal flashes after collectionRemember the sequence, then move through matching domes in that order. A dome may be reused.The late sequence is longer; do not assume the early pattern repeats.
Four spearsFind the light spear in front and use rapid hits. The source calls for twenty hits within about six seconds.High damage with few hits is a poor solution to a hit-count check.
Prison around 50%Other marked players aim all three lines through the prison.Partial coverage only reduces the punishment; complete coverage frees the target.
Late collection plus inward ringsKeep the assigned collection job while jumping incoming rings.Watching only the colours leaves you exposed to the floor.

Difficulty changes & encounter details

Reviewed earlier affixes: elite blood pools harm players and heal monsters; trash deaths strengthen nearby trash. Pull away from healing pools and avoid accidental overlapping packs.

Tank, healer & DPS assignments

Strategy recommendation

Suggested preparation for this encounter. These assignments are editorial recommendations based on the mechanics above.

DPSExecute blade collisions, break the light spear and aim prison lines.

After a wipe: fix the cause

Strategy recommendation

Name the failed mechanic before the next pull. Check whether the target moved too early, the group missed its assignment, or a required cooldown was unavailable. Reassign a backup for any job that can target its original owner. Surviving the mechanic comes before completing a damage rotation.

  • Call the next mechanic before the HP threshold; the actual cast may occur later.
  • If a hit-count object is involved, use fast direct hits rather than assuming a long damage cooldown is better.
  • Save burst for a real vulnerability window after the group has completed its movement.
  • Check the current entry panel for loot probabilities and reward availability before spending another run.
