Wuthering Waves players looking to conquer the formidable Leviathan boss face one of the game's most challenging and fascinating encounters. This powerful Threnodian entity not only serves as a weekly boss challenge but also plays a central antagonistic role in the game's storyline, particularly in Chapter II. With the 2025 updates bringing new challenges and rewards, mastering this fight has become essential for progressing through the game's endgame content.

The Lore Behind Leviathan

In the world of Wuthering Waves (WuWa), Leviathan is a Threnodian entity residing in Rinascita, opposed by the Sentinel Imperator. What makes this boss particularly interesting is that it has corrupted and assimilated with Sentinel Imperator, assuming a hybrid hippocampus form. This corruption allowed Leviathan to take root in the spiritual consciousness of Rinascita's people, manipulating their beliefs through the Order of the Deep in Ragunna City.

According to the game's lore, Leviathan utilizes the Dark Tide to expand its influence, creating Tacet Discords called Dark Tide Creations - disciples that can assimilate other lifeforms. The unique Threnodian-Sentinel assimilation led to the creation of Cartethyia, the "Fleurdelys" who serves as the artificial Sentinel Resonator of this hybrid entity.

Locating Leviathan Boss in Version 2.7

To challenge the Leviathan boss in Wuthering Waves, head to the Three Heroes' Crest location at the foot of the mountains. Note that this weekly boss fight only unlocks after completing the Main Story Quest "Dawn Breaks on Dark Tides."

For players who haven't progressed far enough in the main story, there's an alternative access method. You can challenge Threnodian: Leviathan early by going to the Guidebook and selecting the Weekly Challenge tab. This option was added in the 2.7 update to help newer players access endgame content sooner.

Leviathan Boss Fight Strategy

The 2.7 leviathan boss fight requires careful preparation and strategy. Here are key tactics to overcome this challenging encounter:

1. Movement Patterns: Similar to Fleurdelys, Leviathan can teleport to appear closer or further from your team. Keep it in sight at all times to avoid being caught off-guard by attacks from outside your vision.

2. Attack Mimicry: One of Leviathan's most dangerous abilities is its capacity to mimic Resonator attacks from both Ragunnesi and Septimontian characters. Be prepared to face familiar moves like Cantarella's jellyfish swarms or shots from Iuno's bow.

3. Clone Summoning: The boss can summon inky clones that perform synchronized or staggered attacks, creating challenging dodge scenarios. Focus on evading these coordinated strikes before retaliating when the doppelgangers disappear.

4. Recommended Team Composition: Bring characters with strong Havoc damage potential, as the Leviathan echo's Sonata Effects can amplify this damage type significantly.

Leviathan Boss Rewards and Materials

Defeating that leviathan weekly boss yields valuable rewards:

• Curse of the Abyss: The primary drop used as a Resonator Skill Material for characters released after Version 2.7, including Galbrena.

• Reminiscence: Threnodian - Leviathan Echo: A powerful 4-cost Echo with the following effects at Rarity 5:

• Summons a Collapsing Horizon dealing 131.94% Havoc DMG twice to nearby enemies

• Grants Core of Collapse for 15 seconds, dealing 24.57% Havoc DMG when active Resonators deal damage

• Provides 12.00% Havoc DMG Bonus and 12.00% Resonance Liberation DMG Bonus

The Leviathan echo is particularly valuable for characters who focus on Havoc damage or have frequent attack patterns that can trigger the Core of Collapse effect consistently.

Best Characters for the Leviathan Fight

When tackling the 2.7 leviathan boss, consider bringing these character types:

1. Havoc Specialists: Characters who can apply Havoc Bane to exploit the 100% damage increase from Core of Collapse

2. Rapid Attackers: Resonators who attack frequently to maximize Core of Collapse triggers

3. Ranged Characters: Having at least one ranged character helps during Leviathan's teleportation phases

The Leviathan boss theme creates an intense atmosphere that matches the challenging nature of this encounter. With proper preparation and understanding of its mechanics, even newer players can overcome this formidable opponent and claim its valuable rewards.

As Wuthering Waves continues to evolve in 2025, mastering endgame content like the Leviathan boss fight remains crucial for accessing the best equipment and progressing through the game's challenging content.
