How to obtain Investigation Merits in Zenless Zone Zero

Investigation Merits in Zenless Zone Zero are one of the many currencies players can farm from the special challenges in New Eridu. They primarily serve as tokens rewarded by the Hollow Investigative Association to those who complete dangerous missions for this club. In those quests, players are put through tough battles against the Hollows. These entities, according to the company, are disasters, so getting such benefits upon victory shouldn’t be surprising at all.

Interestingly enough, the hard-earned tokens can be exchanged at a designated store to purchase some valuable resources. This article discusses everything there is to know about obtaining and using the Investigation Merits in ZZZ.

Zenless Zone Zero features multiple gacha currencies, something Proxies who have played the game long enough would know. Aside from the limited ones, there are tokens like the Investigation Merits, which can be exchanged with a vendor for vital supplies. But first, you have to farm them from different sources allocated by the Hollow Investigative Association.

As of this writing, you can obtain Investigation Merits from Shiyu Defense and Notorious Hunt in ZZZ. The former is a battle domain akin to the Forgotten Halls from Honkai Star Rail, where you create teams to defeat enemies across different stages. You can complete Challenge targets while doing this, which will get you good rewards, so it is important to use the best units possible in Shiyu Defense.

On the other hand, the Notorious Hunt is the weekly boss challenge, a recurring feature in almost every gacha game. In it, you will battle against a powerful entity and defeat them to obtain crucial character development materials, among other rewards, including Investigation Merits.

That said, you might not be able to access these challenges right away after signing into a new account, as they are locked behind a certain Inter-Knot Level. So, progress through the story quest to eventually unlock the access points.
