History[]

Icon Threshold Protocol Threshold Protocol[]

After clearing Difficulty V, the Threshold Protocol feature becomes available in Ordinary Extrapolation and Cyclical Extrapolation, providing a further challenge.

Every time the enemy's level increases, the "initial" number below is multiplied, up to four times, until it reaches the listed "final" number at the third plane's boss:

Arithmetic Mapping[]

Planar Ornament Extraction[]

Overview[]

When clearing Ordinary Extrapolation and Cyclical Extrapolation in the Divergent Universe, stage clear data can be saved in a Save File. Save Files can be loaded in the Planar Ornament Extraction system's stages to directly perform Boss Challenges. Respective Planar Ornaments for the corresponding stage will be obtained with successful challenges. Save Files will be reset every Monday at 04:00 (Server time).

When the Equilibrium Level is increased, the Planar Ornament Extraction system will unlock challenges of higher difficulties. The harder the challenge, the more rewards earned, and enemies will be stronger too. Boss difficulty in the Planar Ornament Extraction system is only linked to the challenge's difficulty, and is not related to the Save File's stage clear difficulty. Teams performing Boss Challenges can be freely swapped, and players may deploy 1 Support character to assist in battle.

After completing a challenge, players can choose "One More Time" to perform the same challenge while keeping the effects of used Techniques from the previous challenge.

Note that Arithmetic Mapping is not effective in Planar Ornament Extraction.
