Combat Simulation
Last updated 2026-07-29
Combat Simulation is a game system that allows players to spend 
Battery Charge to fight various enemies for materials. Players can customize the challenge level and the type and amount of enemies to fight which varies the amount of rewards the player receives. Combat Simulation can be accessed by talking to Bertha at the HIA Club.
Details
Combat Simulation is unlocked during Chapter 1: Cat's Lost & Found (A) of Phaethon's Story, with the player only having access to the Basic Material (not including "Plating Agent Specialization"), Agent Promotion, and W-Engine Modification series of challenges at this point. The Agent Skill series of challenges will unlock once the player has progressed through Chapter 1 Intermission.
Each type of challenge will feature a different Enemy Card, representing a specific enemy, with the number of which deciding how much Battery Charge a given challenge will cost, and how many enemies will be faced. Upon unlocking Combat Simulation, the player will only be able to slot in up to 3 Enemy Cards in any given challenge, with the 4th slot becoming available at Inter-Knot Level 20, and the final 5th slot unlocking at Inter-Knot Level 30. Each Enemy Card added, will increase the cost of the challenge by Battery Charge ×20, up to a maximum of Battery Charge ×100 when all 5 slots are in use.
The player can also select a level for the enemies to be at during the challenge, with Level 10 being unlocked by default. Higher levels can be unlocked for each Inter-Knot Reputation Rank the player achieves:
- Level 20 requires
Certified Proxy - Level 30 requires Senior Proxy
- Level 40 requires Elite Proxy
- Level 50 requires Legendary Proxy
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.
Auto Combat
Auto Combat allows the player to consume Ether Batteries to immediately receive rewards for a Combat Simulation or Area Patrol mission. This only applies to missions that cost Battery Charge ×60, and therefore does not apply to custom missions set up in Combat Simulation (which can cost up to 100 Battery Charge).
1 Ether Battery will equal 1 set of rewards from the chosen mission. A maximum of 10 Ether Batteries can be used at one time in Combat Simulation, while for Area Patrol that limit is 4.
Challenge Target
The "Combat Commissions" that can be challenged by Combat Simulation are all titled as Combat Simulation.
The Challenge Targets are universal for all Challenges, regardless of difficulty; and the Rank gained from completing them does not affect the rewards given in any way.
- Complete Combat Simulation
- Finish combat within 2m
