Stygian Onslaught Luna VIII / 6.7 Best Characters and Teams in Genshin Impact

Deepdark Shield: Deeproot Blight

Affected by the Ley Line disturbance, the Lord of the Hidden Depths: Whisperer of Nightmares gathers Abyssal energy to create an extremely durable protective shield. Lunar Reaction DMG is more effective at destroying this shield. When the powerful opponent deploys a shield, the first time the shield takes Lunar reaction DMG, it generates an additional Elemental Orb. When the shield is destroyed, the Lord of the Hidden Depths: Whisperer of Nightmares takes a single instance of immense DMG and temporarily enters a weakened state.

Rift Assault

Affected by the Ley Line disturbance, the Lord of the Hidden Depths: Whisperer of Nightmares will enter a lengthy charging state and summon multiple Fishers of Hidden Depths. Once it has fully charged, it will deal DMG over a large AoE and devour all Fishers. Defeat Fishers before this happens to destroy the Shield and interrupt the Lord of the Hidden Depths: Whisperer of Nightmares' charging.

Suppression Field: Energy Cycler

When combat begins, the Nemesis will deploy 4 detection devices protected by Hydro Wards, constructing a special Suppression Field that will create a Force Shield for the Nemesis and increase all its RES except for Cryo and Electro RES. When the field has been active for some time, the Nemesis will unleash Alpha Strike, dealing AoE DMG over a massive area and retrieving all detection devices. It will then deploy a Hydro Ward whose absorption is based on the number of devices retrieved. Failing to retrieve any detection devices will only grant a weak Hydro Ward.

Force Shield

Due to the Ley Line disturbance, the Nemesis' Suppression Field will fail when the Force Shield is broken, causing the Nemesis to take one instance of massive backlash DMG and enter a state of paralysis. Additionally, each time the Nemesis is affected by a Superconduct or Stellar-Conduct reaction, it will lose a fixed amount of Shield. Superconduct and Stellar-Conduct DMG is more effective at breaking its Shield and will further increase the backlash DMG it takes when the Shield is broken.

Detection Device: Pressurized Component

Detection devices will be destroyed when their Hydro Ward is broken or if they are Frozen and then affected by Shatter, Melt, or other Elemental Reaction DMG. Due to the Ley Line disturbance, the Nemesis' Shield will be damaged for every detection device that is destroyed.

Adaptive Countermeasures: Cold Start

When the battle begins, the Nemesis will be protected by a strong Shield and gain high All Elemental and Physical RES. When a character enters and maintains the Nightsoul's Blessing state, the Nemesis will accumulate progress toward Adaptive Countermeasures. Due to the Ley Line disturbance, after the Nemesis finishes accumulating Adaptive Countermeasures for the first time, it will lose the All RES increase it gained at the start of the battle, its Shield will be broken, and then it will take backlash DMG based on the amount of DMG absorbed by the Shield.

Boltsphere Cannon: High-Pressure Pumps

After Adaptive Countermeasures progress fills up, the Nemesis will activate Accretion Mechanisms and excavate 2 blocks of solid Phlogiston before absorbing energy from within them to charge the Boltsphere Cannon. The Accretion Mechanisms will generate force fields to protect themselves. You must climb up solid Phlogiston to get inside the force fields to destroy them. After all the Accretion Mechanisms are destroyed, Boltsphere Cannon charging will be interrupted, while the Nemesis will get paralyzed and simultaneously take backlash DMG. Due to the Ley Line disorder, Adaptive Countermeasures will accrue progress as time passes, but the threshold required to activate Boltsphere Cannon will be higher.
