High-frequency Elemental DMG | Nightsoul-aligned DMG
It can warp itself and transform into a formidable foe to attack.
Some attacks will inflict the stackable "Attrition" state, which will cause your own active party member to lose HP after a certain amount of time passes.
Due to turbulence in the Ley Lines, the Tenebrous Papilla will deploy a Void Ward while initiating attacks. Perform a certain number of Elemental attacks to break the Ward. Once the Void Ward is broken, the Tenebrous Papilla will receive a single instance of immense DMG based on the DMG absorbed by the Ward and enter a weakened state for an extended period of time. Nightsoul-aligned Elemental attacks are more effective at breaking the Ward and will increase the DMG dealt when the Ward is broken. After being in the weakened state for a while, the Tenebrous Papilla will attempt to re-deploy its Void Ward.
Due to turbulence in the Ley Lines, if the Void Ward remains unbroken for too long, the Tenebrous Papilla will initiate Hatefully Beseech the Dark: Enters a charging state, which, if the Void Ward continues to remain unbroken, will conclude with the Tenebrous Papilla unleashing a Wrathful Dark Bombardment, immediately defeating your current active character. | |
Low-frequency DMG, High-frequency DMG
After taking a certain number of attacks, it will deploy a "Thunderthorn Ward": While the Ward is active, DMG will be reflected to nearby characters when it is attacked. The Ward can be broken by using Elemental Reactions to drain the Ward of Electro.
Due to turbulence in the Ley Lines, every time the foe is attacked, its progress toward deploying a Thunderthorn Ward will increase by a greater amount, but that progress will also gradually decrease over time. In addition, the Elemental requirements for breaking the Thunderthorn Ward are greatly increased. | |
