Raid boss guidesThe Tidebound Grotto
Midnight Season 2 encounter guide

Nymrissa Wavecaller

The Tidebound Grotto's lair boss is a single-phase soak-management fight: Chilling Frost players place Frost Orbs deliberately so soakers can eat them on a schedule, murloc adds must die before the central Alluring Bubble empowers them, and the Unending Tides intermission funnels the raid into the one lane without a whirlpool. Her Abyssal Rain stacks 5 percent frost damage per cast, so a slow kill becomes an enrage.

Before the pull

Set the encounter assignments before pull

  • Special notes: Frost Orb soaking can be immuned; there are no dispels and no interrupts.
  • Assign orb placement and soak duty: Chilling Frost players drop their Frost Orbs in clumps at the edge near the raid, and named soakers run them over before Shatter detonates them.
  • Plan add control: murlocs spawn at the edges and walk to the central bubble - CC, slow, knock, and kill them before they arrive and empower.
  • Position the tank plan: boss held near the add spawns, and in the safe lane during Swirling Whirlpools.
  • Remember this is a once-per-week kill per difficulty that counts toward the raid vault row - bring consumables like it is a raid boss, because it is tuned like one.
Fight flow

Resolve the encounter in this order

  1. 01

    Control the murlocs

    Adds spawn at the arena edges and walk toward the Alluring Bubble in the middle. CC, slow, and kill them on the way - any murloc that reaches the bubble becomes a Bubblefin Berserker, pulsing raid-wide damage until it dies.

  2. 02

    Place the orbs

    Chilling Frost slows its targets and drops Frost Orbs at their location - walk to the edge near the raid first so the orbs land in tidy clumps, never scattered through the play space.

  3. 03

    Soak on schedule

    Touched orbs deal damage, apply a stacking 16 second DoT that raises orb damage taken by 15 percent, and leave a slippery puddle - but an untouched orb Shatters for raid-wide damage and a stacking DoT on everyone. Assigned soakers rotate so nobody stacks the debuff twice in one window.

  4. 04

    Dodge the water

    Swirling Whirlpools send waves rushing from the arena edges toward the bubble - anyone hit takes massive damage. Track the wave lanes while handling adds and orbs.

  5. 05

    Survive Unending Tides

    At the intermission, find the one lane without a whirlpool, stack there, and position for the giant knockback when the whirlpools pop the bubble. Any murlocs that reached the bubble come out of the Tides empowered and CC-immune.

  6. 06

    Beat the ramp

    Abyssal Rain stacks 5 percent increased frost damage on the raid with every cast, and Unending Tides repeats until she dies - the fight is a soft enrage. Return from each intermission, clean up, and push the kill before the stacks own the healers.

Mechanics

What each mechanic asks of you

Alluring Bubble and Bubblefin Berserkers

DPS

No murloc reaches the central bubble: CC and kill every add on the walk.

Failure: Each arrival becomes an empowered Berserker pulsing raid-wide damage - and after the Tides they return CC-immune.

Chilling Frost and Frost Orbs

Debuffed players

Carry the slow to the edge and drop your orbs in the planned clump near the raid.

Failure: Scattered orbs cannot be soaked in time and Shatter one after another into stacking raid-wide DoTs.

Orb soaking

Assigned soakers

Run orbs over on rotation - the 15 percent stacking orb-damage debuff lasts 16 seconds, so alternate soakers and mind the slippery puddles left behind.

Failure: One player greeding consecutive clumps takes lethal orb damage; unsoaked clumps detonate the raid.

Swirling Whirlpools

Everyone

Watch the arena edges and stay out of the water lanes rushing toward the bubble.

Failure: The waves deal massive damage to anyone clipped - usually a death mid-mechanic.

Unending Tides

Everyone

Identify the whirlpool-free lane, stack in it, and brace for the bubble-pop knockback.

Failure: The wrong lane is a raid-wide wipe of crashing water; a bad knockback position throws players into the whirlpools.

Abyssal Rain and Iceblade Flurry

Healers and tanks

Rain stacks 5 percent frost damage per cast on the raid and Flurry channels stacking tank damage - plan the healing ramp and tank swaps.

Failure: Treating the fight as farmable downtime lets the stacks outgrow the healing before the kill lands.

The named boss spells, their individual sub-abilities, and the response for each. Ability names with known spell IDs open their own WoW-God spell pages.

Alluring Bubble

Permanent

A bubble in the middle of the arena that lures murlocs toward it.

Raid response: The bubble is the fail line - the add plan exists to keep it untouched.

Pop!

Intermission

The bursting bubble knocks players back and deals raid-wide damage.

Raid response: Stack in the safe lane with your back to open ground before it bursts.

Bubblefin Berserker

On add arrival

Murlocs that reach the bubble empower and pulse raid-wide damage until defeated.

Raid response: Kill any Berserker immediately - it out-damages everything else on the field.

Swirling Whirlpools

Phase 1

Waves of water rush from the arena edges toward the bubble, dealing massive damage to anyone hit.

Raid response: Track the lanes constantly; reposition early rather than threading them.

Chilling Frost

Phase 1

Debuffs and slows players, dropping Frost Orbs at their location.

Raid response: Walk to the planned clump spot before the orbs drop.

Frost Orb

Phase 1

Touching an orb deals damage, applies a 16 second stacking 15 percent orb-damage debuff, and leaves a slippery puddle.

Raid response: Soak on rotation, respect the debuff timer, and step around the puddles.

Shatter

Phase 1

An untouched orb explodes for raid-wide damage and applies a stacking DoT.

Raid response: This is the punishment the soak rotation exists to prevent - no orb reaches its timer.

Iceblade Flurry

Tank

A channeled tank hit that increases Flurry damage taken.

Raid response: Swap on the debuff and cooldown the channel.

Abyssal Rain

Permanent ramp

Raid-wide damage that permanently increases the boss's frost damage by 5 percent per cast, stacking.

Raid response: The fight's clock: healers ramp with it, DPS race it.

Unending Tides

Intermission

Water crashes down repeatedly, wiping anyone outside the safe lane; repeats until the boss dies.

Raid response: Safe lane, stack, knockback positioning, then back to the kill.

Role plan

Your job in the pull

Tanks

Hold the boss on top of the add spawns so cleave kills the murlocs, move her along the safe lane during Whirlpools, and swap on Iceblade Flurry.

Healers

Single-target the orb soakers through their stacking debuff, and plan for a fight that only gets louder - Abyssal Rain means your strongest cooldowns belong to the later intermissions.

DPS

Murlocs before boss until the walk is clear, then boss - and treat any Bubblefin Berserker as an immediate hard swap.

Everyone

Drop orbs where the plan says, soak only on your turn, and know the safe lane before the Tides start. On Mythic, kill the shielding Bubblefin Frostscale first, expect touched orbs to hit the whole raid, and let the Water Jet clear the lingering puddles.
