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.

Act 8

A creature with two forms that is capable of continuously generating heat. When in its "Geohuman" form, you can use Pyro attacks to cause it to enter its "Molten Dragon" form. At this point, if you continue to use Pyro attacks, it will enter an Overburn state... However, if you manage to cool it down, it will revert back to its "Geohuman" form...

Lava Dragon Statue
A Biting-Cold Wayob Manifestation that once appeared in a special trial.
Will manifest during combat as a "Protection Spirit" and a "Hostile Spirit." Of the two types, the Protection Spirit will create a spirit connection with the character, and when each member of the party receives healing, HP will be recovered for the Protection Spirit. When the Protection Spirit's HP is fully restored, it will use the coordinated attack "Pierce: Binding of Dawn and Dusk's Breaking" to attack the Hostile Spirit. At this time, the more HP is restored to the Protection Spirit, the greater the damage that will be dealt, until finally Pierce: Binding of Dawn and Dusk's Breaking can be transformed into the more powerful Decisive: Binding of Dawn and Dusk's Breaking.
