Wing 1: The Earthen Defense

1. Stone-Warden Gal’zard

The gatekeeper of the sanctum.

• Tank Swap: Taunt on 3 stacks of Petrifying Slam.
• Healers: Dispel Crystalline Curse immediately, but ensure players are spread 8 yards.
• DPS: Focus down the Living Earth adds before they channel Tectonic Shift.

2. The Void-Infused Golem

This fight is a DPS check combined with a dispelling puzzle.

• Mechanic: Players will be marked with Void Resonanace. Run to the corresponding color pillar (Purple or Black) to discharge.
• Mythic Change: In Heroic, failing to discharge wipes the raid. In Mythic, it heals the boss.

Wing 2: The Primalist Council

3. Flameweaver Ko’rag & Frostbinder Sael

A classic twin-boss council fight.

• Positioning: Keep them 40 yards apart to prevent Elemental Concordance.
• Intermission: When Ko’rag shields, melee must swap to Sael. Ranged must break the shield.

Final Boss: Iridikron, the Earth-Warder

The fight against Iridikron is a 4-phase endurance test.

Phase 1: The Hunger of the Earth

Iridikron fights in his visage form.

• Earthspike: Dodge the brown swirls. getting hit applies a permanent slow.
• Galakrond’s Hunger: A focused beam targets a random player. The raid must soak this to split the damage.

Phase 2: Dragonform Descends

At 70%, he transforms.

• Cataclysmic Breath: Covers 1/3 of the room. A massive safe zone indicator appears; move immediately.
• Burrow: He burrows underground. Players must navigate a maze of rocks while avoiding adds.

Phase 3: The Void Bargain

At 40%, Xal’atath interferes (via RP), empowering Iridikron with Void magic.

• Void Zones: Purple circles expand until players stand in them to “shrink” them. Cycles of soak/move.

Phase 4: Enrage

At 10%, soft enrage begins. The room shrinks as the edges collapse. Burn all cooldowns and lust here.

Loot Highlights

• Void-Touched Earth Stone: BiS trinket for Strength DPS.
• Mount: Reins of the Earthen Drake (Rare Drop).

Good luck, champions. The War Within ends here, but the void looms on the horizon.
