Difficulty Levels

Boss 1: Battle-Hardened Pioneer Secret Source Control Array

Mechanics & Tips:

The Battle-Hardened Pioneer Secret Source Control Array: Will of the Hive deploys 4 detection devices at the start of battle, greatly increasing its defensive pressure while the Suppression Field remains active. Each detection device is protected by a Hydro Ward, while the field creates a Force Shield for the boss and increases all of its RES except Cryo and Electro RES. This makes Cryo/Electro and Stellar-Conduct teams the most effective options for weakening the shield and setting up a stronger damage window.

An important strategy is to destroy the detection devices quickly by breaking their Hydro Wards, or by Freezing them and triggering Shatter, Melt, or other Elemental Reaction DMG. Don’t focus only on raw damage while the Force Shield is active, because Superconduct and Stellar-Conduct Reaction DMG help reduce the shield. Breaking the shield causes massive rebound DMG and paralyzes the boss, allowing your main DPS to pressure it more efficiently in Menacing, Fearless, and Dire difficulties.

Recommended Teams

Stellar-Conduct Teams

These teams focus on triggering Stellar-Conduct while keeping strong Cryo and Electro pressure. Since the Battle-Hardened Pioneer Secret Source Control Array loses Force Shield when it takes Superconduct or Stellar-Conduct Reaction DMG, these teams are strong options for breaking its main mechanic and creating safer damage windows. Team 1 uses Sandrone with Yae Miko, Escoffier, and Qiqi for a stable Cryo/Electro setup with healing support. Team 2 adds Wriothesley as an extra Cryo damage dealer while Yae Miko maintains Electro application. Team 3 uses Cyno for stronger Electro pressure, making it a more offensive option for keeping reaction uptime against the Force Shield.

Superconduct Teams

These teams focus on constant Cryo and Electro application without depending fully on a Sandrone-centered Stellar-Conduct setup. Since the Battle-Hardened Pioneer Secret Source Control Array has lower resistance to Cryo and Electro and loses Force Shield when it takes Superconduct Reaction DMG, these teams are strong alternatives for breaking its main mechanic and creating safer damage windows. Team 1 uses Wriothesley with Yae Miko, Furina, and Escoffier for strong Cryo damage, off-field Electro, and Hydro support. Team 2 uses Lohen as another Cryo DPS option, with Yae Miko and Fischl helping maintain Electro uptime. Team 3 uses Varesa as the main Electro DPS, while Escoffier and Citlali provide Cryo support to help weaken the Force Shield.

Boss 2: Lord of the Hidden Depths: Whisperer of Nightmares

Mechanics & Tips:

The Lord of the Hidden Depths: Whisperer of Nightmares — Ravager's Edge gathers Abyssal energy during battle to create an extremely durable Deepdark Shield. This shield is the boss’s main defensive mechanic, and Lunar Reaction DMG is the most effective way to destroy it. Once the shield is broken, the boss takes immense damage and temporarily enters a weakened state, creating a strong damage window for your main DPS.

An important strategy is to interrupt Rift Assault as quickly as possible. During this mechanic, the boss enters a long charging state and summons multiple Fishers of Hidden Depths before unleashing large AoE damage. Don’t focus only on raw damage while the Fishers and Deepdark Shield are active, because defeating the Fishers helps destroy the shield and stop the charge. Breaking the shield quickly makes the fight much safer in Menacing, Fearless, and Dire difficulties.

Recommended Teams

Lunar-Charged Teams

These teams focus on triggering Lunar-Charged with strong Hydro and Electro pressure. Since the Lord of the Hidden Depths has a Deepdark Shield that is weaker to Lunar Reaction DMG, these teams help break its main mechanic faster. Team 1 uses Flins, Ineffa, and Columbina as the strongest core, with Sucrose for reaction support. Team 2 replaces Ineffa with Fischl for easier off-field Electro application. Team 3 uses Ineffa, Columbina, and Fischl for steady Lunar-Charged uptime.

Lunar-Crystallize Teams

These teams focus on triggering Lunar-Crystallize through Hydro and Geo reactions, making them another strong option against the Lord of the Hidden Depths. Since the boss’s Deepdark Shield is weaker to Lunar Reaction DMG, these teams help break its main mechanic while keeping steady Geo-based pressure. Team 1 uses Zibai, Columbina, and Linnea as the core, with Illuga adding extra support. Team 2 keeps the same core but uses Gorou for stronger Geo support. Team 3 uses Navia as the main Geo damage dealer, with Columbina, Linnea, and Furina helping maintain Hydro application and Lunar-Crystallize uptime.

Lunar-Bloom Teams

These teams focus on triggering Lunar-Bloom by combining Hydro and Dendro characters with Lunar Reaction support. Since the Lord of the Hidden Depths relies on an extremely durable Deepdark Shield, Lunar-Bloom teams are effective for dealing steady Lunar Reaction DMG and creating safer damage windows. Team 1 uses Nefer, Columbina, Lauma, and Nilou for a premium Lunar-Bloom setup. Team 2 keeps Nefer and Columbina as the core, with Nahida boosting Dendro damage and Kokomi adding healing. Team 3 uses Lauma, Columbina, Baizhu, and Nilou for a safer setup with strong Dendro support and sustain.

Boss 3: Secret Source Automaton: Configuration Device

Mechanics & Tips:

The Secret Source Automaton: Configuration Device - Lysis Shears starts the battle with greatly increased All Elemental and Physical RES, making it difficult to deal strong damage at the beginning. To remove this defensive state, you need characters who can enter and maintain Nightsoul’s Blessing. As Nightsoul’s Blessing stays active, the boss builds Adaptive Countermeasures, and after this mechanic is completed for the first time, it loses the extra RES gained at the start of the fight.

An important strategy is to interrupt the Boltsphere Cannon before it finishes charging. After Adaptive Countermeasures progress fills up, the boss summons Accretion Mechanisms and creates 2 blocks of solid Phlogiston. Climb the solid Phlogiston to enter the protected force fields and destroy the mechanisms quickly. Once all Accretion Mechanisms are destroyed, the cannon is interrupted, the boss takes massive rebound DMG, and it becomes paralyzed, giving your main DPS a safer damage window in Menacing, Fearless, and Dire difficulties.

Recommended Teams

Nightsoul DPS Teams

These teams use Nightsoul’s Blessing characters to build Adaptive Countermeasures and remove the boss’s starting RES increase. Since the Secret Source Automaton: Configuration Device - Lysis Shears becomes easier to damage after this mechanic, these teams are strong choices for reliable damage windows. Team 1 uses Kinich, Emilie, Mavuika, and Bennett for Dendro/Pyro pressure. Team 2 focuses on Mavuika with Bennett, Citlali, and Xilonen for high Pyro damage. Team 3 uses Varesa with Mavuika, Iansan, and Xianyun for strong Electro damage, while Team 4 uses Mualani with Mavuika, Mona, and Xilonen for Hydro burst damage.

Conclusion

Learning how to break the Force Shield of the Battle-Hardened Pioneer Secret Source Control Array, destroy the Deepdark Shield of the Lord of the Hidden Depths, and counter the Boltsphere Cannon of Secret Source Automaton: Lysis Shears will make each stage much easier.
