📌 1. Basic Formation & Opening Patterns
- Stacking Position: The main tank turns Rahu away from the party, and everyone else stacks tightly behind the boss. All of Rahu's basic attacks are frontal cleaves, so standing on the tank's side is dangerous. Placing a marker behind the boss helps the party hold position throughout the fight.
- Cross-Shaped Attack: Rahu casts a double cross-shaped AoE. Stand still and use Perfect Evasion on the first hit without pressing any direction. You'll automatically dash backward and stay safe from the second hit.
- Close-Range AoE → Donut: Dodge the first close-range AoE, then stay in the safe zone directly behind Rahu to avoid the donut-shaped follow-up.
- Eye Line AoE (Baiting): A random player is marked with an eye icon and a line AoE. The marked player moves toward the arena edge so the line points away from the party, then dashes back to safety before it detonates.
💣 2. Wipe Mechanic: SOS Bomb Debuff
- Overview: Rahu places a 20-second bomb debuff on a random player. You can spot it by the glowing green HP bar, the timer in the party list, and the icon above the player's HP bar.
- Transfer: When the 20-second timer runs out, the carrier must be standing right next to a teammate to pass the bomb.
- Failure: If the carrier is alone when the timer runs out, or dies while holding the bomb, it detonates and leaves a purple AoE field on the ground.
- Wipe Condition: Failing the bomb transfer 3 times wipes the whole party instantly.
- Instant Death: Stepping on a purple AoE field while carrying the bomb detonates it immediately and kills you.
- Party Strategy: If everyone stays stacked behind Rahu, bomb transfers happen automatically, with no need to chase each other.
⭕ 3. Ring AoEs & Mid-Phase Mechanics
- Overlapping Ring Attacks: Rahu targets every player with an individual donut AoE. Stack together to share the safe spot in the center. The tank can either stack with the party (and dodge the frontal cleave right after) or stay separate while both sides jump over each other's shockwaves.
- Wheel of Torment (Teleport Phase): At the first HP threshold, Rahu teleports all players to random spots along the arena edge. Close the gap to the boss quickly and gather on the teammate marked with a stack icon.
- Soaking & Rotation: Rotate around Rahu together while staying stacked on the marked player to share the damage. You can tank the close-range AoE on the way back and recover with heals or potions.
- Placing AoE Fields at the Edge: If Rahu raises his weapon after the rotation, run to the arena edge so the permanent AoE fields drop away from the center. Keep track of the bomb carrier while moving so no transfer is missed.
- Lingering Laser Attack: Rahu strikes behind himself first, then in front. Dodge the rear attack and stay on the safe side until the lasers end. The hitbox stays active even after the red ground indicator disappears.
⚔️ 4. 50% HP Phase: Arena Split into 4 Sections
- Arena Division: At 50% HP, Rahu splits the arena into four quadrants. Your movement space shrinks while bomb transfers continue.
- Tank Positioning: Rahu jumps onto the main tank. The tank should bait the jump toward the center of the arena to preserve fighting space.
- Managing AoE Fields & 2-Part AoEs: Drop new AoE fields near the outer edges, away from the center. When Rahu casts his 2-part AoE, the tank should stand on the side with the most open space so the party has a clear escape route.
👁️ 5. Final HP Threshold: Feeding Time
- Monster Spawns: In the final phase, additional monsters spawn around the edge of the arena.
- Aiming the Eye Attack: Rahu marks a random player with an eye icon and a line AoE. The marked player must aim the line through one of the spawned monsters to kill it.
- Wipe Escalation: Every monster left alive counts toward the same 3-fail wipe limit as a missed bomb transfer.
- Final Burn: Stay tightly stacked for bomb transfers and keep clearing monsters with the eye line AoE until Rahu goes down!
💡 Key Tips
- Never lose track of the bomb carrier: Most wipes happen when players split up to place AoE fields or bait the eye line and forget to pass the bomb.
- Watch for lingering hitboxes: Don't step back into Rahu's laser path just because the ground indicator has disappeared.
- Save your fails for Feeding Time: Clean bomb transfers early on leave you room for mistakes during the chaotic add phase.
