Three fountains - Blood, Fire, and Shadow - ring the room, and Vashnik's Imbibe draws from the TWO closest, empowering his next explosion and summoning that pair's adds, which crawl toward the central pool. The tank chooses each mix by where the boss stands, and the raid CCs and kills every add before it reaches the center.
The tank positions Vashnik between the two fountains the raid wants next. Each Imbibe empowers the following raid-wide explosion, raises add health from those fountains, and stacks - so rotate deliberately rather than camping one spot.
Every Imbibe summons adds that crawl toward the central pool. CC, root, slow, and kill them before any arrives - one add reaching the pool triggers Malignant Burst and a stacking 30 second DoT on the raid.
Malignant Catalyst deals raid-wide damage and rains Catalytic Bile soak circles after it - every circle needs a player standing in it or it explodes.
Plague Froth debuffs players who, after 8 seconds, fire Plague Waves in the four cardinal directions. Run out and aim the waves away from the raid - and on Mythic, aim them through the Malignant Tumors.
Each fountain pair hands out its Adaptive Infections: Blood players stack with allies and siphon to clear, Fire players run out before exploding, Shadow players call for the absorb to be healed off while spraying dodgeable swirlies.
Every rotation the empowerment stack grows and the tank's Dripping Fangs DoT climbs - keep the add kill clean, rotate tank cooldowns, and race the ramp.
Boss position selects the two fountains drawn from. Move him each cast so empowerments rotate instead of stacking one pair out of control.
Failure: Camping one pair stacks the same empowerments and add types until they overwhelm the raid.
No add may reach the central pool - CC and kill every crawler.
Failure: Each arrival explodes the pool and applies a stacking DoT to the raid for 30 seconds.
After the raid-wide hit, catch every falling Bile circle.
Failure: Unsoaked Bile explodes into more raid-wide damage during an already heavy window.
Run out and aim the four cardinal Plague Waves away from the raid.
Failure: Waves through the raid deal avoidable damage - and on Mythic a missed Tumor wipes the raid.
Blood: stack with allies and siphon while unhealable. Fire: run out and explode at distance. Shadow: healers burn the absorb off while everyone dodges the swirlies.
Failure: An unresolved infection either kills its carrier or feeds damage into the raid.
A stacking tank DoT that raises damage taken - rotate cooldowns and externals as the mix count climbs.
Failure: Ignoring the stack turns routine fountain rotations into tank deaths.

Vashnik draws from the two nearest fountains, empowering the next Imbibe explosion and summoning adds that crawl toward the center pool.
Raid response: The tank chooses the mix by position; the raid readies for that pair's adds and infections.
Any add reaching the center pool explodes it, applying a stacking DoT to the raid for 30 seconds.
Raid response: Treat every crawler as lethal: CC, slow, and kill before arrival.
Light stacking raid damage every 2 seconds for the whole fight.
Raid response: Healers pace mana - the fight's baseline damage never stops.
Raid-wide damage that shoots out Catalytic Bile circles which explode if not caught.
Raid response: Assigned players catch every circle immediately after the hit.
Debuffed players shoot Plague Waves in the four cardinal directions after 8 seconds.
Raid response: Run out, square up, aim the waves into empty space - or through Mythic Tumors.
A stacking DoT on the tank that increases damage taken.
Raid response: Cooldown rotation and disciplined swaps as stacks rise.
One add immune to CC until destroyed, splitting into smaller adds.
Raid response: Nuke it first; cleave the splits before they spread.
Two pulsing adds that explode with a stacking DoT when defeated; CC-able but immune to CC after 60 seconds.
Raid response: Kill them one at a time to stagger the explosions, gripping them together first if possible.
Many adds shielded for 100 percent of their health, spraying dodgeable swirlies when killed.
Raid response: Root and CC the pack, break shields with AoE, and dodge the death swirlies.
Siphoning (Blood) blocks healing until life is leeched from stacked allies; Exploding (Fire) detonates at distance; Stygian (Shadow) is a healing absorb that sprays swirlies until removed.
Raid response: Each infection has one correct answer - stack, run, or heal through - and the raid calls it early.
You steer the whole fight: park Vashnik between the chosen fountains, rotate the mix each Imbibe, and treat Dripping Fangs stacks as your swap and cooldown clock.
Hold cooldowns for Fire add explosions and the Catalyst window, burn Stygian absorbs off fast, and remember Siphoning players cannot be healed - they need bodies nearby, not casts.
Adds before boss, always: nuke Blood, stagger Fire kills one at a time, root and AoE Shadow packs. The center pool staying untouched is your scoreboard.
Know which two fountains are live and what that means for your infection. Catch Bile circles, aim Froth away, and never funnel adds through the middle.
