The Spire of the Watcher dungeon in Destiny 2 presents Guardians with intense challenges, and the Akelous, The Siren’s Current boss fight stands out as a pivotal second encounter. Set in a vast Vex-infested arena on Mars within an ancient Seraph facility, this battle combines familiar mechanics from past raids with unique twists that demand precision, coordination, and high damage output. Whether you’re running a fireteam or attempting a solo clear, understanding the flow—from powering Arc nodes to dismantling the boss’s defenses—is key to victory.
Encounter Overview and Arena Layout
Akelous awaits in a sprawling central platform ringed by four bridges, each leading to an Arc node platform. Yellow energy conduits link these nodes back to the center, mirroring the wiring puzzle from the prior Spire Ascent section. The boss, a massive Vex harpy, hovers menacingly, occasionally devouring a Minotaur in a grim display of dominance. Harpies and other adds spawn relentlessly, adding pressure during key phases.
The fight cycles through charging phases and damage windows. Guardians must grab the Arctrician buff by interacting with Arc charges, then deposit energy into all four nodes in sequence. Completing this activates the DPS phase, where Akelous exposes vulnerabilities. Repeat until the boss’s health depletes. In higher difficulties like Ultimatum or Contest mode, efficiency becomes critical to avoid wipes from overwhelming adds or failed mechanics.
- Central Platform: Safe starting zone and primary DPS spot.
- Four Bridges: Paths to Arc nodes; coordinate to avoid splitting too early.
- Node Platforms: Deposit sites; watch for Vex teleports and lasers.
Core Mechanics: Charging the Nodes
Begin by defeating initial Vex waves to spawn Arc charges. One player grabs the Arctrician buff (a temporary empowerment that lets you pick up and deposit energy). Start at the central platform, channeling energy into the wires until the first node pulses. Proceed bridge-by-bridge, ensuring the buff holder deposits at each before it expires.
Key rule: Power the final node only when your entire team is positioned on that bridge. This prevents stragglers from missing the DPS phase, maximizing collective damage. If someone lags, the boss retreats prematurely, wasting time.
| Step | Action | Team Tip |
|---|---|---|
| 1 | Grab Arctrician from charges | Designate a runner (e.g., Hunter for mobility) |
| 2 | Deposit at Node 1 (center to bridge) | Clear adds en route |
| 3 | Repeat for Nodes 2-3 | Callouts for buff expiry |
| 4 | All on final bridge for Node 4 | Synch to trigger DPS |
Missteps like early final-node activation lead to suboptimal damage, especially in Contest mode where phases are unforgiving.
Damage Phase Breakdown
Once nodes are charged, Akelous unfurls its wings, revealing multiple glowing red eyes. Rapidly shoot these weak points—prioritize speed, as quicker clears extend the DPS window. After all eyes shatter, the boss’s central shield drops, exposing a massive white critical spot on its underbelly.
Akelous then drifts toward the central platform, lingering vulnerably without a barrier (unlike similar fights in Garden of Salvation). Pour damage into the crit spot. Linear Fusion Rifles excel here due to the boss’s retreat path and easy headshot alignment. Watch for a knockback pulse at phase end—position defensively.
Harpies swarm aggressively, firing lasers from afar. Prioritize 2-3 per phase to maintain clear sightlines. Well of Radiance or Song of Flame supers provide sustain against add pressure.
Optimal Loadouts and Builds
Success hinges on weapons and abilities tuned for node-running, add clear, and boss DPS. Focus on Arc synergies for buffs, but mix elements for versatility.
Primary Weapons
- For Eyes: Izanagi’s Burden or any high-burst scout/linear fusion for quick multi-hits.
- Add Clear: Trinity Ghoul (Arc chain lightning) or Riskrunner (Arc Conductor procs).
Heavy Weapons
Queenbreaker (for 2-phase Ultimatum clears) or Indebted Kindred shine in linear fusion slots. Overflow perks on Hezen’s Vengeance aid solo ammo economy.
Class Builds
- Warlock: Song of Flame with Speakers Sight for team healing/DPS amp.
- Titan: Arc setup for survivability and node speed.
- Hunter: Mobility for buff transport; Star-Eater Scales for orb generation.
In solo runs, prioritize overflow heavies and Well of Tenacity for self-sustain. Videos demonstrate 1-2 phase clears with minimal optimization.
Team Coordination Strategies
For three-player fireteams, assign roles clearly:
- Node Runner: Fast class (Hunter/Titan) handles Arctrician deposits.
- Add Clear/Caller: Manages Harpies, directs node order.
- DPS Anchor: Preps heavy ammo, focuses eyes then crit.
Voice comms are essential: “Buff grabbed, Node 1 clear!” or “Eyes down, dumping damage!” In Contest mode, aim for 2-phase kills using Queenbreaker and coordinated supers.
Solo Flawless Techniques
Soloing Akelous demands patience and ammo management. Use Hezen’s Vengeance (overflow) for sustained heavies. Cycle nodes methodically, using platform cover against Harpies. Extend DPS by eye-shooting speed—practice yields 1-phase potential.
Build for longevity: Prismatic or Arc with healing fragments. Recent clears show Rite of the Nine solos, proving accessibility with practice.
Common Pitfalls and Fixes
- Split Team on Final Node: Wasted DPS—always regroup.
- Harpie Snipes: Clear aggressively; use cover.
- Buff Expiry: Grab charges proactively.
- Knockback: Root with Frost or Barricade.
Advanced Tips for Speedruns
Optimize for 1-2 phases: Pre-load heavies, use Well of Radiance mid-DPS. Arc 3.0 verbs (Jolts, Blind) shred adds. Track Spire’s weekly rotations for pinnacle gear rewards.
