| Enemy | Descriptions |
|---|---|
   Characters | Crowd Control Characters
When battle begins, the Nemesis enters the Agglomerated State, during which all RES is greatly increased. While in this state, the Nemesis's Agglomeration Energy is constantly consumed. Dealing Pyro or Electro DMG to the Nemesis drains this energy more quickly. When its Agglomeration Energy is fully depleted, the Nemesis unleashes Sporebloom and switches to the Split State.
When this Nemesis enters the Split State, it splits into a large number of spores. When these spores take damage, a certain percentage of the total damage is also dealt to the Nemesis. After remaining in the Split State for a period of time, the Nemesis will return to the Agglomerated State. In this case, if the number of spores on the field falls below a certain number, the Nemesis will enter the Brittle Agglomerated State, during which all RES is greatly reduced and its combat abilities are diminished. Additionally, if all spores generated in Split State are defeated, the Nemesis will exit the Split State early and go into the Brittle Agglomerated State instead. | |
 Lv. 40 Knuckle Duckle: Normal |
 Reactions | Characters
Once the battle has progressed to a certain point, this Nemesis will go into Duckstruction Mode, in which its aggression increases. It also generates a Ward for itself that increases all RES and summons floating Stamping Devices to harass you.
Stamping devices are fairly resistant to all DMG except Electro DMG. Deal Electro-Charged or Lunar-Charged DMG repeatedly, or deal enough damage to destroy them to disrupt these devices. Disrupted stamping devices will go out of control, crash into the Knuckle Duckle, and deal a certain amount of damage to its Ward. By destroying the Nemesis's Ward this way, you can cause it to exit Duckstruction Mode and become incapacitated from Overloaded. |
 characters
Will enter Sweeper Mode while in combat: All Elemental and Physical RES is greatly increased, and it will generate Flow Momentum while performing attacks. The higher its Flow Momentum, the faster it will rotate and the more DMG it will deal.
If an active character enters and maintains the Nightsoul's Blessing state for a time, this opponent will enter Counterstrike Mode and switch to attacking with tracking rays. At this time, its All Elemental and Physical RES will be decreased. |

| Lv. 105 Knuckle Duckle: Armored Arsenal |
Reactions | Characters
Due to the effects of the Ley Line disturbance, when battle begins, this Nemesis will go into Heavy Duckstruction Mode, in which its aggression increases. It also generates a Ward for itself that increases all RES, and summons floating Stamping Devices to harass you.
Deal Electro-Charged or Lunar-Charged DMG repeatedly, or simply deal enough damage to destroy the stamping devices to disrupt them. Disrupted devices will lose control and crash into the Knuckle Duckle, dealing a certain amount of damage to its Ward. Destroying the Nemesis's Ward this way will cause it to exit Heavy Duckstruction Mode and become incapacitated from Overloaded. This will also greatly reduce the Nemesis's Electro RES for a certain time.
Due to the effects of the Ley Line disturbance, the stamping devices become more resilient — deal more instances of Electro-Charged or Lunar-Charged DMG or more damage to these devices to disrupt them. Electro-Charged or Lunar-Charged DMG dealt to stamping devices will be more effective, and when they lose control and crash into the Knuckle Duckle, the damage dealt to the latter increases based on the total damage taken by the devices. |

Descriptions
Now, under the negative influence of the Ley Lines, its territorial consciousness has been severely distorted and intensified, and it greets every intruder with blatant, unrestrained hostility.
Disturbed by the chaotic surging of the Ley Lines, its formerly vigorous vitality has been heavily depleted, turning it into the source of a green spore calamity.
Amidst the inchoate chaos of the Ley Lines, its form has long since mutated, and it is now determined to harness the howling winds to let its spores swallow the land whole...
Due to the Ley Line disturbance, its projection manifests more strongly as a weapon, unleashing crushing blows on all who draw near.
The misalignments in the Ley Line have caused its projection to join forces with the stamping devices, forming a fearsome strike force that is poised to crush all threats.
Due to the transformation caused by the extreme Ley Line disorder, the projection of this mechanism has evolved into a mobile factory fully loaded with armor and weaponry. One wrong move, and a swarm of Stamping Devices will overwhelm the challenger like a tsunami...
In the distant past, a once-mighty ancient race used this mechanism to oversee the operation of their cities. Even now, long after the fall of their civilization, it still retains immense authority.
It has returned to this realm via Ley Line memories once again to perform its "abnormality cleansing" duties...
In the distant past, a once-mighty ancient race used this mechanism to oversee the operation of their cities. Even now, long after the fall of their civilization, it still retains immense authority.
The Ley Line narratives can restore even the most decrepit machines to mint condition. This device, as if freshly combat-adjusted, can now unleash even more lethal attacks...
In the distant past, a once-mighty ancient race used this mechanism to oversee the operation of their cities. Even now, long after the fall of their civilization, it still retains immense authority.
In the depths of the chaotic Ley Lines, the core energy module that deteriorated over the lengthening years has been restored, indeed, even "overclocked" to a dangerous degree. This machine is now unchained by its original specifications, capable of freeing itself from the planet's shackles and using its horrific "Obliterator Panoply"...
