HIA Club Activities
VR Device: Combat Simulation
The main thing players can do at the HIA Club is to spend Battery Charge on the Combat Simulations in the VR Device Challenge.
Accessible by speaking to Bertha, the red-haired NPC, Combat Simulations have a set of stages that drop various materials that can be used as currency, as components for strengthening Agents and W-Engines, and more.
VR Device: Expert Challenge
Progressing through Chapter 2: A Call From the Hollow's Heart and completing the Mechanical Love Investigation Commission and Let's go Bro! Investigation Commission will unlock the Expert Challenge stages in the HIA Club.
These stages drop materials used to upgrade an Agent's Core Skills. To access these stages, speak with Lyla, the blue-haired NPC at the counter.
HIA Club Rewards
Rewards for Spending Battery
Aside from getting the item drops mentioned above, there are also rewards for spending certain amounts of Battery Charge on the Combat Simulations.
The rewards can be viewed by clicking on the Reward Icon in the bottom left of the Combat Simulation menu. These rewards are tied to Inter-Knot Level, so be sure to keep raising it for more access to these rewards!
How to Raise Your Inter-Knot Level
