Expert Challenge
Last updated 2025-09-21
Expert Challenge is a game system that allows players to spend
Battery Charge and complete various challenges in exchange for Higher Dimensional Data and Master Copies. Players can choose the challenge level, which varies the amount and rank of rewards received. Expert Challenge can be accessed by talking to Lyla at the HIA Club.
Details
Expert Challenge is unlocked during Chapter 2: A Call From the Hollow's Heart (A) of Phaethon's Story.
Each type of challenge will feature a different Enemy, and will award a different type of Higher Dimensional Data, which can be used to level-up various Agent's Core Skills. Depending on the level of the challenge selected, either Audio Booster Master Copy, or Noise Reduction Master Copy will also be awarded, allowing the player to craft -Rank or -Rank Drive Discs at Bardic Needle.
The player can also select a level for the enemies to be at during the challenge, with Level 25 being unlocked by default. Higher levels can be unlocked for each Inter-Knot Reputation Rank the player achieves:
- Level 25 (default) Certified Proxy
- Level 35 requires Senior Proxy
- Level 45 requires Elite Proxy
- Level 55 requires Legendary Proxy
No matter the level selected, each challenge will cost either
Battery Charge ×40 or
Battery Charge ×80, solely depending on whether or not Burnout Mode is turned on.
Immersive Mode
Immersive Mode is a game system unlocked at Inter-Knot Level 30. It primarily affects Combat Simulation and Expert Challenge at the HIA. When toggled on, in-game time will no longer pass after having undertaken challenges.
Burnout Mode
Added in Version 1.6, Burnout Mode allows the player to consume double the usual amount of battery charge (80 instead of 40), in order to receive double the amount of rewards in a single Expert Challenge. Burnout Mode is only available for stages that award Higher Dimensional Data that are used by the limited -Rank Agents that are currently-running on the Exclusive Channel.
