WHERE & HOW TO FARM

Where to farm

HIA Club VR Training, Combat Simulation, Modify W-Engine stage type.

Combat Simulation’s Modify W-Engine category supplies materials for W-Engine upgrades. Identify the item shown on the target engine’s modification screen, then select the stage whose reward preview matches it. Clear, claim, and verify the material stock before spending more Battery Charge. This is a repeatable resource route for engine progression, separate from Agent promotion and skill stages.

GET STARTED

How to farm

Before you go

Unlock Combat Simulation in HIA Club VR Training.
Have a W-Engine whose next modification requires materials.
Check the required item on that W-Engine’s upgrade screen.

Open the target W-Engine’s modification screen and note the required material.
Go to HIA Club VR Training and select Combat Simulation.
Choose the Modify W-Engine stage category.
Compare stage reward previews and select the one listing the needed item.
Clear the stage and claim the materials.
Return to the W-Engine screen and check whether the intended modification is now affordable.
Repeat the matching stage only if the next planned upgrade still needs that material.
Apply the materials to modify the engine when the requirement is met.

Farming tips

Use the W-Engine screen as the source of the exact item name; do not infer it from the engine’s rarity or name.
Combat Simulation has distinct categories for Agent Promotion and Agent Skill, so confirm Modify W-Engine before entering.

Repeat, collect and use

The stage can be repeated with Battery Charge as needed. Its purpose is to fund planned W-Engine modifications, not to collect an unlimited stock without a target.

Common mistakes

Selecting Agent material stages for an engine upgrade; use Modify W-Engine.
Choosing by stage label alone without checking the listed item; match the reward preview.
Continuing after the desired modification is funded; reassess whether the engine remains a priority.

When to stop or switch

Stop once the intended W-Engine modification is funded, then redirect Battery Charge to the next needed agent, skill, or disc upgrade.
