Genshin Impact Weekly Boss - All-Devouring Narwahl
The All-devouring Narwahl summary
The All-Devouring Narwhal is a weekly boss in Genshin Impact, introduced in Fontaine. Found in the Salacia Plains Trounce Domain, it’s a massive abyssal whale with Hydro and Electro attacks. The battle has two phases: players first fight it on the surface, then get swallowed to face its inner core, the Dark Shadow. Arkhe (Pneuma/Ousia) attacks are crucial to progress through both phases. The boss drops unique materials like Lightless Silk String and Eye of the Maelstrom, used to ascend Fontaine characters. Its complex mechanics and cinematic design make it a standout late-game challenge.
The All-Devouring Narwhal is a weekly boss introduced in Genshin Impact as part of the Fontaine region content. This massive, abyssal whale resides in the Trounce Domain located in Salacia Plains, unlocked after completing Archon Quest Chapter IV, Act V.
The battle is split into two main phases. In the first phase, the Narwhal uses powerful Hydro-based AoE attacks like body slams, geysers, and beams. During this phase, players must monitor the "hostility" gauge. When it fills up, the boss summons an Eye of the Maelstrom, which must be destroyed using characters with Arkhe (Pneuma or Ousia) abilities. Destroying the eye triggers the boss to swallow the player, beginning the second phase.
Inside the Narwhal, players face a separate entity known as the Dark Shadow, an Electro-infused core that summons elemental constructs. The core periodically enters an orb form vulnerable only to Arkhe-based attacks. Successfully defeating the Dark Shadow deals major damage to the Narwhal and stuns it temporarily, allowing players to return to the surface and deliver heavy burst damage before repeating the cycle.
Strategically, players should avoid using Hydro DPS in the first phase and Electro DPS in the second due to elemental resistances. Characters like Furina, Lynette, or Charlotte are highly recommended for their Arkhe abilities. Healers or shielders (e.g., Zhongli, Bennett) also help manage survivability.
The boss drops unique materials such as Lightless Silk String, Lightless Mass, and Eye of the Maelstrom, which are essential for ascending Fontaine characters. With its intricate mechanics and striking visual design, the All-Devouring Narwhal is both a narrative centerpiece and a challenging endgame encounter.

Battle Mechanics
**Two-phase fight**:
• **Phase 1 – Whale Assault**: Boss stays mostly submerged, periodically surfacing to slam with Hydro AoE and cracks. Use strong damage orbs (“Eye of Maelstrom”) and avoid Hydro resistance.
• **Phase 2 – Shadow Realm**: You’re swallowed — fight a Shadow Phantom inside the belly. Deals Electro/Hydro damage, protected by shields. Must break shields using Pneuma/Ousia or Arkhe attacks to stun and return to Phase 1.
Whale is **70% resistant to Hydro** in Phase 1 and **70% resistant to Electro** during Phase 2 shadow fight — avoid bringing those elements accordingly.
Phase 1 involves large ground slams and crack zones—dodge these AoE attacks.
Phase 2 features shielded shadow wielding sword, energy nodes, summons, and orb mechanics—use Pneuma/Ousia to break shields and interrupt strong attacks.
After defeating the shadow, the boss briefly becomes vulnerable on the surface for heavy DPS—maximize burst during this window.
Appropriate team comp includes:
– One Fontaine character for Arkhe Energy to damage the Eye of Maelstrom,
– Strong DPS (Pyro, Cryo, Anemo, Dendro),
– Shields or healers, and Pneuma/Ousia user.
