Total amount of EXP materials you need to reach level 60 in ZZZ

Agent levels are crucial for tackling tougher challenges. While completing quests and missions grants some EXP, the primary way to level up your characters is by using Investigator Logs.

Reaching level 60, the maximum level, requires a significant amount of EXP, totaling around 900,000 points. This translates roughly to using 300 Senior Investigator Logs, the rarest and most valuable EXP material.

As you progress, leveling up becomes more costly. This means you’ll need a higher number of Investigator Logs, especially Senior ones, to reach higher levels.

Given the resource investment, it’s wise to prioritize leveling up characters who play key roles in your team composition.

The best candidates are typically your Damage per Second (DPS) characters, those who can inflict heavy damage, your Stun characters who can control enemies, and your Support characters who buff your team. These roles are essential for a well-rounded team composition that can conquer challenging content.

The easiest way to farm Investigator Logs in ZZZ

Looking for the easiest way to farm Investigator Logs and power up your characters? Look no further than the Hollow Investigative Association (HIA) Club.

This helpful feature unlocks after completing the Cat’s Lost and Found main story commission, which becomes available after finishing the Chapter 1 Intermission. Once unlocked, simply head to the HIA Club and talk to Bertha.

She’ll offer you access to a VR training program called Combat Simulation, where the real farming magic happens.

Hamster Cage Pass: Your key to Agent power in ZZZ

Combat Simulation allows you to tailor the challenge by picking the specific enemies you want to face. The key here is to choose enemies that have a chance of dropping Senior Investigator Logs. While you can check enemy info for potential drops, it’s not always guaranteed.

While picking the easiest difficulty might seem tempting, remember that higher difficulty levels offer better rewards. Try to find a sweet spot where you can comfortably complete the challenge but still get the most Investigator Logs possible.

By following these steps, you can turn the HIA Club’s Combat Simulation into a reliable source of Investigator Logs, helping you level up your characters to conquer tougher challenges in ZZZ.
