Hey Raiders, since we're diving deep into Icecrown Citadel, I put together a quick-reference guide covering all 12 bosses from the Lower Spire to the Frozen Throne. This focuses on the must-know mechanics for progression. Good luck taking down the Lich King!



1. The Lower Spire (Bosses 1-4)


Lord Marrowgar

Key Mechanic: Bone Spike Graveyard (Impales players) and Bone Storm (Boss spins and chases).

Strategy Tip: DPS must kill the Bone Spike immediately. When Bone Storm hits, spread out and run away from the boss's path.

Lady Deathwhisper

Key Mechanic: Mana Shield must be broken. Adds (Adherents/Fanatics) must be killed. Mind Control on random players.

Strategy Tip: P1: Kill adds quickly, DPS shield. P2: Tank boss, use CC or damage on the Mind Controlled player to break the effect instantly.

Gunship Battle

Key Mechanic: Use Cannons to attack the enemy ship. Use Rocket Packs to jump across.

Strategy Tip: Assign Roles: Most stay on cannons/adds. A few rocket pack over to kill the Sergeant and Mage on the enemy ship to stop its cannons.

Deathbringer Saurfang

Key Mechanic: Blood Beasts (Give the boss Blood Power if they hit the raid). Mark of the Fallen Champion (Damages marked player, fuels Blood Power).

Strategy Tip: Ranged DPS must slow and kill the Blood Beasts before they reach anyone. Minimize Blood Power gain to prevent boss from gaining 100 Power too quickly.




2. The Plagueworks (Bosses 5-7)

Festergut

Key Mechanic: Gas Spore (Green cloud for resistance buff). Vile Gas (Orange debuff, run away from others).

Strategy Tip: Stack for Spores to build resistance stacks for the heavy damage phases (Inhales). Spread out from the raid for Vile Gas.

Rotface

Key Mechanic: Mutated Infection (Spawns Small Ooze when it expires). Oozes merge into a Big Ooze that must be kited.

Strategy Tip: Infected players run to the kite zone. Off-Tank must continuously kite the Big Ooze around the room.

Professor Putricide

Key Mechanic: Volatile Ooze and Gas Cloud (Adds that chase players). Malleable Goo (Green slime puddles).

Strategy Tip: P1/P2: Kill adds and avoid Goo. P3 (Burn Phase at 35%): All adds stop. Pop Heroism/Bloodlust and burn the boss before the continuous room damage wipes the raid.



3. Crimson & Frostwing Halls (Bosses 8-11)
Blood Prince Council

Key Mechanic: Three Princes fight simultaneously, one is Empowered. Keleseth (Dark Nucleus Orbs), Taldaram (Flame Spheres), Valanar (Kinetic Bombs).

Strategy Tip: Focus the Empowered Prince. Coordinate movement for the Orbs (Keleseth) and Bombs (Valanar) to manage the damage.

Blood-Queen Lana’thel

Key Mechanic: Vampiric Bite (Creates a vampire, must bite another player before 60 seconds). Pact of the Darkfallen (Linked players must run together).

Strategy Tip: Maintain the Bite Chain (bite $approx$ every 45-50s) to prevent a player from being Mind Controlled. Air Phase: Hide behind a pillar to avoid incoming damage.

Valithria Dreamwalker (HEALING FIGHT)

Key Mechanic: Must HEAL the Dragon to 100% HP. Portals spawn for Healers to enter and gain a stacking healing buff.

Strategy Tip: Healers stack the buff in the portals, then focus heal the dragon. DPS/Tanks must quickly kill all adds, especially Suppressers.

Sindragosa

Key Mechanic: Unchained Magic (Casters stop casting). Frost Beacon/Ice Tomb (Frozen players must be freed). Mystic Buffet (Stacking debuff in P3).

Strategy Tip: Break Ice Tombs fast. Hide behind Ice Tombs during Blistering Cold. P3: Rotate between DPS and hiding behind Tombs to reset Mystic Buffet stacks.


4. The Frozen Throne (The Lich King)


The final test combines multiple mechanics across three phases and a transition:

P1 (100-70%)

Mechanics: Necrotic Plague (Tank Swap). Defile (grows if stood in). Infest (Raid-wide damage).

Strategy: Defile Placement is KEY—move it away from the raid immediately to prevent it from growing and wiping the group. Tanks swap at 3 stacks of Plague.

P2 (70-40%)

Mechanics: Raging Spirit (Adds). Val'kyr Shadowguards (Grabs players). Ice Spheres (Adds).

Strategy: Slow/Stun the Val'kyr to prevent players from being dropped off the edge. Off-tank the Spirits.

Transition (40%)

Strategy: Kill all Raging/Wicked Spirits inside the Frostmourne room and heal up.

P3 (40-10%)

Mechanics: Vile Spirits (Explode on impact). Harvest Soul (Player ported away). Defile/Val'kyr continues.

Strategy: Focus Vile Spirits before they reach the raid. Break Harvest Soul victims out. Defile must continue to be handled perfectly.

Final Phase (10%)

Mechanics: Fury of Frostmourne (Wipe mechanic).

Strategy: Survive. Pop Heroism/Bloodlust and finish the boss before the wipe mechanic finishes you!
