Act 3

Nemesis of Coppelius: the main lead here is the clockwork meka Coppelius. At the climax of the performance, Coppelius will halt at the center of the dance floor and expose his artificed clockwork component charged with pneuma, thereby drastically increasing the efficiency of his exertions, granting him a shield, and generating three retributive Frosthearts. During this phase, using ousia-imbued attacks will effectively break his shield and overload him, thus progressing the performance.

Act 6

This ancient aggregation of machinery hails from the desert and has quirks that modern-day civilizations cannot comprehend. In battle, the Algorithm of Semi-Intransient Matrix of Overseer Network will fire its components out while its core enters an "invisible" state that hides it and increases its RES. Use Catalyze reactions to strike this core, or use Electro attacks on it during such times as the fired components have been destroyed and need to recover to cancel this invisibility and cause the core to be immobilized due to overclocking. If you fail to cancel the core's invisibility for too long, the Algorithm of Semi-Intransient Matrix of Overseer Network will begin to display its power by using a mighty overclocked attack...

Algorithm of Semi-Intransient Matrix of Overseer Network
The gigantic combined form of many water droplets. During the challenge, small Half-Tulpas will constantly appear and fight against their opponents. The Hydro Tulpa will absorb these Half-Tulpas into itself to grow stronger. You can use attacks or Elemental Reactions to disrupt this absorption process.

Hydro Tulpa
A great black monster that has come from the abyssal dark, eroding the memories of the earth. It can warp itself and transform into a formidable foe. Some of its attacks can cause stackable Attrition that, after a time, will cause your active character to lose HP. During combat, the Tenebrous Papilla will use Beseech the Dark to grant itself a Void Ward. At this time, use a certain number of elemental attacks to break the Ward, which will cause it to enter a confused state. Nightsoul-aligned elemental attacks will break the Ward more effectively.
