Difficulty Levels

Boss 1: Battle-Hardened Glacial Wolf

Mechanics & Tips:

The Battle-Hardened Glacial Wolf summons an Ancestral Spirit during battle, greatly increasing its overall resistance while the spirit remains active. The Ancestral Spirit is protected by a Frozen Ward that ignores most incoming attacks and must be depleted by triggering Pyro Swirl or Electro Swirl reactions near it. This makes Pyro/Anemo and Electro/Anemo teams the most effective options for breaking the ward and weakening the boss’s defensive state.

An important strategy is to keep applying Pyro or Electro to the boss while using Anemo attacks to trigger constant Swirl reactions. Don’t focus only on raw damage while the Ancestral Spirit is active, because the boss becomes much harder to defeat if you ignore the ward mechanic. Breaking the spirit’s protection quickly creates a much better damage window, allowing your main DPS to pressure the boss more efficiently in Menacing, Fearless, and Dire difficulties.

Recommended Teams

Pyro/Anemo Teams

These teams focus on triggering Pyro Swirl reactions while maintaining strong Pyro and Anemo damage pressure. Since the Battle-Hardened Glacial Wolf favors Pyro/Anemo reactions, these teams are among the strongest options for breaking through the boss’s special mechanics and creating reliable damage windows. Team 1 is the strongest Hexerei-focused option, using Varka as the main DPS with Nicole, Durin, and Prune providing strong Pyro/Anemo synergy. Team 2 focuses on Arlecchino’s high Pyro damage while Kazuha enables consistent Pyro Swirls and Xilonen provides resistance shred. Team 3 uses Mavuika as the main Pyro DPS with Bennett, Kazuha, and Xilonen for a powerful high-investment Pyro core.

Electro/Anemo Teams

These teams use Electro application and Anemo support to trigger frequent Electro Swirl reactions. While Pyro/Anemo teams are generally stronger for Varka’s personal damage, Electro/Anemo teams remain strong alternatives for this boss because the battlefield also favors Electro/Anemo reactions. Team 1 uses Varka with Double Anemo and Double Electro for consistent Swirl uptime and safer clears. Team 2 focuses on Clorinde and Fischl for fast Electro damage, with Kazuha enabling Electro Swirl and Nahida boosting Aggravate damage. Team 3 uses Raiden Shogun’s strong burst damage with Kazuha’s Electro Swirl support and Bennett’s powerful ATK buff.

Boss 2: Hydro Tulpa

Mechanics & Tips:

The Hydro Tulpa summons Half-Tulpas during battle and attempts to absorb them to enhance itself. If the boss successfully absorbs these summons, it can restore HP, increase its ATK, and become much more dangerous. This makes Pyro characters the most effective option for destroying the Half-Tulpas quickly, while Freeze can also help interrupt the absorption before the Hydro Tulpa powers up.

An important strategy is to prioritize the Half-Tulpas instead of focusing only on raw damage against the main boss. Don’t ignore the summons, because allowing the Hydro Tulpa to absorb them makes the fight harder and can reduce your chances of clearing within the time limit. Breaking its Ward and stopping Torrential Flurry quickly creates a much safer damage window, allowing your main DPS to pressure the boss more efficiently in Menacing, Fearless, and Dire difficulties.

Recommended Teams

Pyro DPS Teams

These teams use powerful Pyro DPS characters to take advantage of the Hydro Tulpa’s permanent Hydro nature and the battlefield’s Pyro character advantage. Since the Hydro Tulpa summons Half-Tulpas and can absorb them to restore HP and increase its resistance, fast Pyro damage is extremely valuable for clearing the summons and pressuring the boss at the same time. Team 1 uses Mavuika with Bennett, Citlali, and Xilonen for a premium Pyro setup with strong damage and defensive comfort. Team 2 focuses on Arlecchino’s high Pyro damage, with Kazuha increasing reaction damage and Citlali helping control the Half-Tulpas. Team 3 uses Gaming as a more accessible Pyro DPS option, combining Bennett, Xianyun, and Citlali for strong plunge damage and safer clears. Team 4 uses Lyney as a ranged Pyro DPS, with Bennett and Xiangling providing strong Pyro support while Zhongli protects him during Charged Attacks.

Freeze Control Teams

These teams focus on controlling the Half-Tulpas before the Hydro Tulpa can absorb them. While Pyro DPS teams are generally the strongest option for this battlefield, Freeze-based teams can help stop the boss from powering up and create safer damage windows. Team 1 uses Skirk with Escoffier, Furina, and Citlali for a powerful Hydro/Cryo setup that fits Skirk’s preferred team structure. Team 2 uses Wriothesley with Bennett and Xiangling to add Pyro damage while Citlali provides Cryo utility and defensive comfort. Team 3 uses Ayaka as a Cryo burst DPS with Shenhe and Citlali supporting her damage while Bennett adds Pyro utility for breaking through the boss’s mechanics.

Boss 3: The Open-Eyed

Mechanics & Tips:

The Open-Eyed enters the Supreme Overseer state during battle, allowing it to monitor Pyro, Hydro, Electro, and Cryo hits it receives. After receiving enough hits from one element, it records that element and repeats this process across two monitoring phases. After completing two instances of Supreme Overseer, the boss prepares Phenomena’s Delirium and summons two corresponding Elemental Stars based on the recorded elements. Destroying both Elemental Stars interrupts the attack and briefly stuns the boss, while failing to do so allows the attack to continue and makes the fight much more dangerous.

An important strategy is to control which elements the boss records by using teams that match the battlefield’s advantages: Pyro/Cryo reactions and Hydro/Pyro reactions. Don’t apply random elements during the monitoring phase, because the boss may summon stars that your team cannot destroy efficiently. Instead, focus on consistent Melt or Vaporize setups, then quickly break the Elemental Stars when they appear. Interrupting Phenomena’s Delirium creates a safer damage window, allowing your main DPS to pressure the boss more efficiently in Menacing, Fearless, and Dire difficulties.

Recommended Teams

Melt Teams

These teams use Pyro and Cryo reactions to match the battlefield advantage while controlling which elements the boss records during Supreme Overseer. Since The Open-Eyed summons Elemental Stars based on the recorded elements, Melt teams are especially effective because they bring both Pyro and Cryo damage to break the stars efficiently. Team 1 uses Lohen as the main Cryo DPS with Nicole and Durin enabling strong Melt synergy. Team 2 focuses on Mavuika’s powerful Pyro damage, with Citlali providing Cryo utility and defensive comfort. Team 3 uses Wriothesley as an on-field Cryo DPS while Bennett and Xiangling provide consistent Pyro application for Reverse Melt damage.

Vaporize Teams

These teams focus on Hydro/Pyro reactions, which are also favored in this battlefield. Vaporize teams are strong because they provide fast Pyro and Hydro hits, making it easier to control the boss’s recorded elements and destroy the corresponding Elemental Stars before Phenomena’s Delirium finishes charging. Team 1 uses Arlecchino as the main Pyro DPS with Yelan’s Hydro application and Kazuha’s damage support. Team 2 focuses on Hu Tao’s single-target Vaporize damage, with Yelan and Xingqiu providing reliable Hydro application while Zhongli gives strong protection. Team 3 uses Mualani as the main Hydro DPS with Mavuika and Xiangling providing Pyro application for strong Vaporize damage windows.

Conclusion

In conclusion, a solid understanding of each boss’s mechanics, combined with proper team composition and sufficient character investment, is the key to consistently clearing all stages. Taking the time to learn the mechanics of the Battle-Hardened Glacial Wolf, Hydro Tulpa, and The Open-Eyed will significantly improve both your efficiency and overall experience.
