What are Expert Challenges?

Defeat Bosses to Farm Core Skill Mats

Expert Challenges are straightforward VR battles that bring you against a singular Elite Enemy, that rewards Proxies with valuable materials for their Agents. Each stage can modify both the Agent's or the Boss' stat.

Materials from these challenges are mainly used to upgrade Core Skills, like their respective Passives.

Costs Battery Charges

Like any other VR Modes, Expert Challenges would cost Battery Charges. Here, it will cost you 40 Battery Charges in one challenge.

However, Proxies can challenge these stages as much as they can, as long as they have enough charges per round.
