The Cloud Deck (Extreme) Guide – Diamond Weapon Mechanics & Strategy

Encounter Overview

The Cloud Deck (Extreme) is a high-mobility, platform-based encounter that revolves around split-party coordination, teleport timing, and layered mechanic resolution across two arenas. Players must constantly evaluate positioning, platform safety, and debuff windows to survive overlapping mechanics.

The fight emphasizes structured movement and role discipline, with mechanics frequently forcing players to divide into light parties and execute mirrored responsibilities across platforms. :contentReference[oaicite:0]{index=0}

Arena Overview

The encounter takes place across two floating platforms connected by teleport pads. Falling from either platform results in death, making knockback control and positioning critical throughout the fight.

Teleporters allow players to swap platforms but apply a temporary lockout debuff, preventing immediate reuse. Proper rotation between groups is required to handle raidwide damage and platform-targeted mechanics.

Mechanic Archive

Diamond Rain

Raidwide damage based on number of players on a platform.

Micro-strategy:

• Split into two light parties
• Rotate platforms between casts
• Never stack full party on one side

Adamant Purge

Platform cleave + follow-up (stack or spread).

Execution:

• Move to safe platform immediately
• Read boss glow:
• Chest → stack
• Shoulders → spread

Photon Burst

Tank flare markers.

Execution:

• Tanks go corners
• Party moves opposite side
• Mitigate + heal immediately after

Articulated Bits

Tether + knockback mechanic.

Micro-strategy:

• Stretch tether (turn purple)
• Use knockback to reposition between platforms
• Stand at edge for controlled landing

Airship’s Bane

Destroys a platform.

Execution: Immediate platform swap—no hesitation.

Outrage

Heavy raidwide damage.

Execution: Mitigate + top before next mechanic.

Auri Arts

Zig-zag and directional charge attacks.

Micro-strategy:

• Use platform triangles as safe anchors
• Identify boss facing early
• Commit to position—don’t over-adjust

Auri Doomstead

Tankbuster with debuff.

Execution: Tank swap every cast.

Vertical Cleave

Knockback slam.

Execution:

• Stand near impact point to minimize knockback
• Or use knockback immunity

Diamond Shrapnel

Chasing AoE markers.

Execution:

• Bait away from group
• Teleport after placement

Adamant Sphere

Meteor soak mechanic.

Execution:

• One player per circle
• Maintain spacing from lasers

---

Phase 3 Mechanics

Flood Ray

Sequential conal attacks on players.

Micro-strategy:

• Split by marker (even vs odd)
• Bait cones to corners
• Rotate positions after each hit

Bits + Adamant Purge

Combined laser + platform mechanic.

Execution:

• Wait for lasers → then teleport
• Resolve stack/spread safely after

Bits + Diamond Shrapnel

Chasing AoEs + lasers.

Execution:

• Bait markers on unsafe side
• Teleport to safe platform after drop

Encounter Flow

Phase 1 – Platform Discipline

The encounter opens with strict light party splitting and platform rotation.

Core loop:

• Diamond Rain → platform swap
• Adamant Purge → safe platform + resolve stack/spread
• Tank mechanics → isolate damage

Key skill: Managing teleport timing without overlapping debuffs.

Phase 2 – Movement Complexity

The boss sheds armor and introduces layered movement mechanics.

Players must now handle:

• Knockback repositioning (Bits)
• Platform destruction
• Directional movement patterns

Failure point: Misreading safe zones or mistiming knockbacks.

Phase 3 – Precision Execution

The final phase combines all prior mechanics with stricter positioning requirements.

Flood Ray introduces sequencing discipline, forcing players to rotate positions cleanly.

Combined mechanics now require:

• Correct platform swaps
• Clean baiting of AoEs
• Accurate spacing under pressure

Key success factor:

Commitment to assigned positions. Most wipes occur from hesitation or overlap.

The encounter ends with a Flood Ray enrage if DPS is insufficient.
