The VR mode allows you to use your Battery Charges and earn various rewards from Dennies and Ascension Materials for Agents. If you're familiar with any gacha game, the very first thing you will want to do is unlock dungeons and stages where you can spend your daily stamina to level up quickly.

The HIA club, where the VR training is located, is unlocked after completing the Cat's Lost and Found Main Commission in Chapter 1. You'll be tasked with going to Coff Cafe and receiving extra battery power. After that, you will be made to go to the HIA club. This is where you can unlock the VR training and farm materials in Zenless Zone Zero.

The HIA club offers many training stages in which you can complete the following challenges:

• Basic Materials: Used to farm Dennies, W-Engine batteries, and Investigator logs.
• Agent Promotion: Drops Promotion materials for various Agents in the game.
• W-Engine Materials: Drops both W-Engine Batteries and necessary materials to promote them.
• Agent Skill: Drops skill materials that can be used to upgrade an Agent's Skills.
• Custom: This challenge lets you customize what you need efficiently.

Custom will only be unlocked after you reach Level 30 on Inter-Knot, which can be upgraded by completing various missions and dailies and running the VR device for materials farming in Zenless Zone Zero.

The VR training in the HIA also lets you increase a challenge's difficulty. Doing so will consume more Battery but will give better rewards in terms of both quality and quantity. However, the quality will be tied down to your Inter-Knot level in Zenless Zone Zero.
