Control which two fountains empower each 100-energy wave, kill every venom before it reaches the center, and alternate colors so no fountain reaches three stacks.
Boss mechanics
Tank swap
Swap after every Dripping Fangs hit.
DO THIS: Swap exactly on this trigger and call it early.ALTARS
Viewed from the entrance, mark Fire left, Shadow right and Blood at the far side. Start between Fire + Shadow.
ROTATION
Move Fire + Shadow → Shadow + Blood → Blood + Fire. Blood is farther away, so pull Vashnik fully into position and confirm the two active glows.
RAID
Loose stack behind the boss. Ranged Catalyst soakers step away from the boss, soak fully, then return.
INFECTIONS
Fire goes to the far outer edge; Shadow drops its pool at the edge; Blood briefly stays near the raid. Point Plague Froth waves away from everyone.
Role assignments
Tanks
- Swap immediately after each Dripping Fangs; it leaves a long physical vulnerability.
- Keep Vashnik locked between the called fountains and do not rotate him during Heroic projectile lanes.
- Pick up adds without letting any reach the center.
Healers
- Fire target moves away; its raid hit scales with proximity.
- Heal through Shadow’s absorb, then the player exits the resulting pool.
- Blood applies a severe absorb/reduction: briefly stack allies in its aura to heal the target.
Damage dealers
- Living Venom is absolute priority. Slow and stun susceptible adds.
- Fire adds explode on death—stagger kills when the raid is unstable.
- Blood adds split on death; Shadow adds pressure their nearest target.

- 02

The two nearest fountains empower the boss and spawn Living Venom. Kill every blob before it reaches the central pool.
- 03
INFECTIONS
Fire goes far out, Shadow is healed through then leaves a pool, Blood needs allies briefly inside its aura to feed healing into the target.
Difficulty changes
Follow the exact three-step fountain rotation. Keep the boss facing fixed when projectile directions matter.
Stationary tumors cast a lethal ability. Aim Plague Froth waves through them; each needs repeated wave hits before removal.
