Vashnik the Malignant

Position Vashnik between the next two fountains before he reaches full energy and casts Imbibe.

The two closest fountains activate, spawning their adds and applying the corresponding player debuffs.

Once every add is dead, move Vashnik to the next pair of fountains and repeat the cycle.

One fountain overlaps between consecutive pairs and becomes stronger when activated twice in a row. Prepare extra healing for its second activation.

The large add cannot be crowd controlled. Focus it down, then immediately cleave the smaller adds created when it dies.

Players marked with a leech circle cannot be healed until several other players stand inside their circle. Collapse quickly to release them.

Stack and AoE the small adds, then dodge the swirlies they fire when they die.

Targeted players receive a healing absorb and repeatedly create swirlies beneath their feet. Keep moving while healers remove the absorb.

Both adds pulse raid-wide damage while alive and explode when killed. Bring them down together and stabilise between deaths.

HeroicEach add death also applies a stacking damage-over-time effect to the entire raid.

Run large explosion circles away from the raid to reduce their damage, then return after they resolve.

Taunt after each Dripping Fangs cast so the tank debuff does not remain on the same player.

Use personal defensives and healing cooldowns for the heavy raid-wide damage.

HeroicMalignant Catalyst is a major recurring raid-damage event; plan healing cooldown coverage before the pull.
