Vashnik is a single phase fight built on a 1:24 Imbibe cycle: each window the two active fountains hit the raid together, spawn living venoms, and stack his vapor higher. Cooldowns are planned to the Imbibe windows; everything between them is layered rot and targeted damage that grows to the end.
- 1Imbibe (every 1:24): Vashnik drains the two active fountains. Their Expulsions hit the raid as one burst when the cast ends, living venoms spawn from both sides, and the vapor stacks once more.
- 2Kill the venoms: The venoms crawl toward the central cavity and must die before they arrive; one getting through is a wipe-level burst. On Fire cycles every dying wave hits the raid.
- 3Debuffs and orbs: Infections go out twice per cycle, Plague Froth coats players, and the Catalyst orb explodes with bile soaks in between. The middle of every cycle is rot plus targeted damage.
- 4Clear and reset repeats: The second infection of each cycle is still ticking when the next Imbibe lands unless it is dispelled, so clear it early and top the raid before the window. Then it repeats.
Toxic Vapor stacks with every Imbibe and never resets, so the whole fight ramps. The closing stretch is the hardest healing of the fight purely because of it.
Every 1:24 an Imbibe opens the fight's damage window: the fountains' burst as the cast ends, then the dying venoms and the malignant burst right after. Raid cooldowns cover that whole window, and a repeated fountain hits about twice as hard.
The spacing fits no cooldown cleanly: 1 and 2 minute cooldowns end up holding, 1.5 and 3 minute cooldowns drift a window. After the sixth Imbibe the cycle collapses into rapid final casts.

Ability timeline
Your Cooldown Plan
Every 1:24 Vashnik drains the two active fountains and opens the fight's damage window: the Expulsion burst as the cast ends, the living venoms dying into raid damage, and the malignant burst, all landing back to back.
Plan raid healing cooldowns to carry the whole stretch rather than one moment, coverage that lingers earns its full value on top of the ramping vapor.
The 1:24 spacing fits no cooldown cleanly: 1 and 2 minute cooldowns come back early and end up holding, while 1.5 and 3 minute cooldowns run slightly long and drift a window later across the fight. Expect a rotation that shifts rather than a fixed per-window mirror.
A fountain kept in for back to back cycles hits about twice as hard, so weight the heavier covers toward the repeated-side windows of your chosen rotation.
After the sixth Imbibe the cycle collapses into rapid casts with the final pair locked in and still stacking, on top of fully ramped vapor. Hold real cover for that closing stretch.
Twice per cycle Vashnik explodes an orb of venom over the central cavity: a raid hit plus Catalytic Bile sprays that each need to catch at least one player. A spray that lands on nobody punishes the whole raid much harder.
The first hit of each pair lands inside the Imbibe window, the second sits mid cycle, and both matter more late in the fight when the vapor is high.
The bile sprays are a soak check, not a healing check: make sure every spray is caught.
Other boss mechanics
Hemo Expulsion공격대 피해Blood's share of the Imbibe burst: an unavoidable raid hit the moment Imbibe ends, growing by roughly its opening size for every consecutive cycle Blood stays in, so a second cycle lands about twice as hard. Covered by the Imbibe plan.
Conflagrating Expulsion공격대 피해Fire's share of the Imbibe burst: an unavoidable raid hit the moment Imbibe ends, growing for every consecutive cycle Fire stays in. Covered by the Imbibe plan.
Gloom Expulsion공격대 피해Shadow's share of the Imbibe burst: an unavoidable raid hit the moment Imbibe ends, growing for every consecutive cycle Shadow stays in. Covered by the Imbibe plan.
Toxic Vapor공격대 도트, Ramping RotThe chamber's rot: it stacks with every Imbibe, ticks from pull to kill, and never resets. Every mechanic hits into a higher floor as the fight goes on, and the closing stretch is the hardest part of the fight because of it.
Burning Presence공격대 도트While Burning Venoms are alive on Fire cycles, their presence pulses steady fire damage into the whole raid. It stops when the venoms are dead, so it rewards killing them fast.
Caustic Surge공격대 도트, 공격대 피해On Fire cycles the Burning Venoms explode as they die, each wave hitting the whole raid and stacking a short DoT. The waves follow your kill speed, not a boss timer, so healing follows the adds dying.
Siphoning Infection공격대 디버프Blood infection: a heavy DoT that shuts off the target's healing received and pulses damage into anyone nearby. Keep infected players out of the group and dispel it. A good spot for a personal defensive.
Exploding Infection공격대 디버프, 산개Fire infection: a ticking DoT that detonates raid-wide when removed, so dispels are timed, not spammed. The target holds a personal for the ticks and the raid expects the burst. Mythic: it stacks until dispelled, so it cannot be left to sit.
Stygian Infection공격대 디버프Shadow infection: a short DoT with a healing absorb that repeatedly bursts the ground at the target's location. Move it away from the group and heal through the absorb; personals help here.
Plague Froth이동, 공격대 디버프Corrosive venom on six players, once on the opener and twice per cycle after that: it hurts anyone near them, and on expiry Plague Waves erupt in cardinal directions, dodge those. Mythic: the expiry waves are also the tool that destroys the Malignant Tumors Imbibe conjures, and a tumor that gets its cast off hits the whole raid with stacking poison.
