Zenless Zone Zero Investigation License Boost
Investigation License Boost is a ZZZ in-game service that increases your Investigation License level in Zenless Zone Zero by completing high-difficulty Hollow Zero stages like Withered Domain and Lost Seed, earning maximum Investigation Points, and unlocking rewards such as Polychromes, Boopons, Denny, and rare upgrade materials like Booressure Cores and W-Engine parts. This service focuses on reaching the weekly point cap efficiently, using first-clear bonuses and optimized intensity runs to fast-track your license progression. The Investigation License acts as your Hollow career rank, unlocking faction respect, new Bounty Commissions, and improved supply drops. ChaosBoost handles the full boost process manually, ensuring every run contributes the highest point value while completing weekly tasks and claiming milestone rewards. By boosting your Investigation License, you gain faster access to endgame content, powerful Agent upgrade items, and prestige as a top-tier Proxy in Zenless Zone Zero.
Rewards
Leveling the Investigation License in Zenless Zone Zero unlocks a steady stream of valuable rewards that directly support Agent growth, team strength, and overall progression. Each rank gained through an Investigation License Boost from ChaosBoost delivers in-game currency, rare items, and exclusive upgrade materials that usually require weeks of consistent farming. These rewards represent the core incentive behind every Proxy’s desire to increase their Investigation License rank quickly and efficiently.
- Polychromes – ~40 per license level; used for Battery refills or purchasing Master Tapes in the Signal Shop. These are essential for maintaining run frequency in ZZZ and supporting gacha currency needs over time.
- Denny – Up to 50,000 per milestone rank; used for upgrading Agents, gear, and W-Engines. A stable Denny supply ensures consistent progression through all upgrade systems in ZZZ.
- Boopons – Special gacha tickets for Bangboo Channel Signal Searches; chance at rare items and intel. Boopons help fuel important Bangboo development in ZZZ, especially for support units and materials.
- Inter-Knot Credits – Given at certain levels (e.g. 600 credits); used for Proxy reputation and faction shop exchanges. These credits serve as key trade currency in ZZZ for exclusive shop rewards and unlocking trust levels.
- Upgrade Materials – Includes Booressure Cores, Bangboo System Widgets, Winding Roses, and Fragrant Infusions for advanced Agent and gear enhancement. These materials are difficult to farm regularly in ZZZ, making license-level rewards a critical resource path.
- Consumables & Misc – Includes Ether Electrolyte, Energy Transfer Fluid, Ether Fuel, and Cooling Fluid for sustaining combat and Hollow activities. These extra items improve combat efficiency and Hollow Zero stamina economy in ZZZ.
Every reward earned during an Investigation License Boost is permanently added to your inventory and ready for immediate use. Zenless Zone Zero players benefit greatly from these high-value items, especially when accumulated across dozens of license levels. With ChaosBoost, every possible reward tier is hit efficiently, turning your Investigation License into a rich supply vault.

Requirements
To begin an Investigation License Boost in Zenless Zone Zero, a few essential conditions must be met to guarantee efficient progress through Hollow Zero. These requirements align with standard progression in Zenless Zone Zero and ensure access to the systems that generate Investigation Points. Meeting these prerequisites allows the boost to function smoothly within the game’s weekly structure and content limits.
- Unlocked Hollow Zero Mode – After completing the Qualification Assessment mission, access to Hollow Zero becomes available — the main investigation zone within ZZZ, where license progression begins.
- Investigation License System Enabled – The license interface appears in the Proxy profile shortly after unlocking Hollow Zero, acting as a key tracking system in ZZZ for Hollow activity and progression.
- Agents at Level 20+ – A minimum of one full team with level 20+ Agents is recommended to survive mid-intensity combat in ZZZ, especially in stages like Lost Seed 5/11 or Withered Domain 6/11.
- Functional Team Setup – A balanced squad featuring damage dealers, support, and defense roles — or Bangboo synergy — is vital for stable Hollow Zero runs throughout ZZZ.
- Unlocked Weekly Features – Systems like Bounty Commissions and License Rewards must be accessible, since weekly progression in ZZZ depends on those limited-time content cycles.
With these elements in place, any Investigation License Boost in Zenless Zone Zero can move forward at full pace. These are natural parts of standard progression and reflect readiness for deeper Hollow activity. Once met, every Hollow run directly contributes to faster license growth and greater reward gain in Zenless Zone Zero.

FAQ
Even experienced Proxies in Zenless Zone Zero often want clarity before starting an Investigation License Boost. Understanding how the boost works, what’s needed, and what to expect helps eliminate confusion and build confidence. Below are answers to the most relevant in-game questions surrounding the process. Each one is based on real gameplay systems and the experience of Proxies who’ve gone through the boost journey.
Is the Investigation License Boost service safe for my account?
The entire process is fully manual and follows the natural rules of Zenless Zone Zero, with no third-party software involved. VPN login from your region is used to avoid suspicious access flags and ensure safety. There’s no interaction with friends, mail, or social systems, and no changes are made to unrelated content. Boosts are executed cleanly, with every action focused on progressing the Investigation License only.
Do I need high-level Agents or meta teams for the boost?
While high-level Agents can speed things up, they are not required to begin an Investigation License Boost. Even teams made up of 4 star units can clear necessary Hollow Zero stages when used with proper tactics and synergy. If stronger characters are available, more difficult stages can be cleared for faster point gain. Any account with Hollow Zero unlocked can start the boost process regardless of team power.
How long does an Investigation License Boost take from start to finish?
The time depends on starting rank, the desired end goal, and the weekly Investigation Point cap. Small boosts are often completed in 1–2 days, while full rank boosts may stretch across several weekly resets. Efficient gameplay ensures all weekly caps are reached immediately after reset for rapid progress. Larger boosts may take multiple weeks, but every reset is used to its fullest potential.
What rewards will I receive during and after the boost?
Every reward unlocked during the Investigation License progression is fully retained by the account. This includes all Polychromes, Denny, Boopons, Inter-Knot Credits, and upgrade items like Booressure Cores and Winding Roses. Loot from Hollow Zero runs, such as dropped gear, currency, and rare parts, is also kept. After the boost, all resources will be available in your inventory with nothing missing or claimed externally.
