CROWN OF THE COSMOS Raid Boss Guide | Normal/Heroic Tips

Crown of the Cosmos: Phase One Strategies

In the Crown of the Cosmos encounter, your journey begins with phase one where you face the challenge of defeating three undying sentinels. Each of these sentinels is strategically positioned on a platform and must remain close to their corresponding void portals. They share common abilities but bring unique challenges that require careful handling.

Sentinel Abilities and Strategies

To ensure efficient handling of the sentinels, consider the following key points:

1. Echoing Darkness: When no player is within melee range, this ability causes group damage and increases the sentinel's damage output by 4% on heroic. Assign tanks to spread out to minimize these casts.
2. Umbreal Tether: To kill the sentinels, this buff must be removed using Yria's Silver Strike Arrow. Aim the arrow at a sentinel after piercing two players to dispel the tether effectively.
3. Individual Sentinel Skills:
   • Morium: Employs Dark Hand, causing a knockback. Tanks should use defensive abilities or positioning to avoid falling off the platform.
   • Demiar: Uses Interrupting Tremor, capable of disrupting spell casting. Casters need to be vigilant.
   • Vorlus: Casts Ravenous Abyss, an AoE mechanism reducing player damage within its range. Step out quickly to avoid debuffs.

Void Droplets and Buff Management

• Droplets spawn from the portals and need grouping and quick disposal beneath the sentinels, as their explosion amplifies the damage taken by sentinels through a stacking debuff.
• Beware of duplicating the Silver Strike arrow's effect, which can unintentionally clear these valuable debuffs.

Managing Additional Mechanics

• Magic Debuff - Null Corona: It's a heavy healing absorb and should not be dispelled unless necessary, as it can spread to nearby players.

• Grasp of the Void: Generates a void zone and emits lasers upon expiration. Players should position themselves strategically to direct the lasers away from the group.

• Void Expulsion: A static void zone appears under a random player, requiring baiting to the platform's edge.

Tactical Execution

1. Initial Focus: Group around Morium, taking him down first while dispelling puddles and managing droplets strategically.
2. Rotation Strategy:
   • Once Morium is down, shift focus to Demiar by routing damage swiftly.
   • After Demiar, concentrate on Vorlus. With amassed droplets, this phase should close swiftly.
3. Arrow Sequence: Align your Silver Strike arrows in the order of Morium, Demiar, and then Vorlus.
4. Healer Coordination: Ensure a healer is within range of the tank managing Vorlus, as increased droplet counts pose a risk.

Transition to First Intermission

Upon defeating the undying sentinels, prepare for the first intermission. Yria begins to fracture the arena, adding new dynamics:

• Arena Mechanics:
• Manage a stacking dot and increased vulnerability to knockbacks.
• Avoid being pulled under Yria by maintaining distance.
• Dodge singularity eruption circles to avert knockback effects.

• Debuff Management: Utilize Silver Strike Barrage lines to clear debuffs, but avoid excessive stacking by clearing every other wave, especially on heroic.

Your success in these initial phases sets the stage for the challenges ahead, preparing your raid for the intensified battle that follows.

Phase Two: Efficient Boss and Ad Management

In this phase, coordination is key to managing the space within the arena effectively. The strategy is to split the raid into two groups, with melee players positioned in the center and ranged players near the edge. This setup allows the team to efficiently bait and handle the void expulsion puddles.

Key Tactics:

• Tank Swapping: Swap tanks when Simulacrum's Rift Slash stacks reach about two to three. Taunting must occur simultaneously to ensure bosses switch places smoothly.
• Ad Control: Handle the undying void spawn ads by using crowd control and interrupts. Death grips are handy for gathering ads near the melee camp.
• Positioning: Position players debuffed by Ranger Captain's Mark to ensure Silver Strike Ricochet hits the ads, enabling their defeat.

1. Start with Yria in the middle and employ death grips to usher ads close for a ricochet hit.
2. Proceed to eliminate the Simulacrum's cosmic barrier with the entire raid aiding from a central position.
3. Sync boss swaps with the appearance of new ads to maintain control over the arena space.

   Defensive Cooldowns and Debuff Management:

   • Utilize abilities like Rally and Anti-Magic Zone (AMZ) during heavy damage phases, primarily when dealing with double void expulsion hits on heroic difficulty.
   • Clear Voidstalker Sting stacks with Silver Strike Ricochet to prevent complications from extended debuffs, especially in heroic mode.

Intermission and Transition to Phase Three

Following the destruction of the Simulacrum, you'll enter the second intermission, which mirrors the first but introduces orbiting matter to complicate positioning. On heroic difficulty, a wall of these rotates around Yria, necessitating strategic movement to avoid unnecessary damage.

Transitioning Tips:

• Use movement cooldowns to keep up with rotation and avoid orbiting matter.
• Prepare for Phase Three by positioning your group together to ensure a safe transition as the arena fractures.

Final Phase: Racing Against Time

The final phase focuses on defeating Yria swiftly to avoid the arena being overtaken by devouring Cosmos void energy. Prioritize using bloodlust and damage potions immediately to maximize DPS output.

Final Phase Mechanics:

1. Aspect of the End: Manages DOTs and stagger debuff breaks among melee, ranged, and tanks to mitigate raid-wide damage.
2. Positioning Strategy: Stay stacked to bait grasp of emptiness void zones efficiently. Move as a unit to avoid incoming lasers.
3. Navigating the Arena: Position near area edges before devouring Cosmos casts. Utilize movement abilities or dark rush feathers to traverse gaps as needed.

   Here's a simplified guide to these mechanics:

The race is against time in this phase; the objective is to defeat Yria before all sections fill with void energy. Stay alert, manage positions strategically, and remember that agility and coordination are key to victory.
