Zenless Zone Zero Help Kai Event Guide: Introduction

Throughout the Help Kai Event, players will have multiple opportunities to complete event-specific tasks and earn valuable rewards. The event introduces Weekly Goals, which provide a structured way to engage with various in-game activities, refreshing at a set interval to ensure a steady flow of objectives. By completing these tasks, players can earn key resources such as Polychromes, Boopons, upgrade materials, and other essential items needed for progression.
To make the most of the event, players should focus on efficiently clearing their Weekly Goals before the next reset, ensuring that no potential rewards are missed. Since these objectives are designed to align with regular gameplay, players can integrate them into their daily activities while also working toward other in-game milestones. Prioritizing high-value tasks first can help optimize resource acquisition, making it easier to strengthen agents and prepare for upcoming content. Active participation will not only yield immediate benefits but also contribute to long-term progression, allowing players to build a more powerful roster while making steady advancements in Zenless Zone Zero.
Event Duration

The Help Kai Event in Zenless Zone Zero will take place over two weeks, starting on December 2nd, 2024, at 04:00 (server time) and concluding on December 16th, 2024, at 03:59 (server time). Throughout this duration, players will have access to two full cycles of Weekly Goals, which reset every Monday at 04:00 (server time). This structure allows participants to steadily progress through event tasks while maximizing their rewards. Efficient time management is crucial to completing all available objectives before the event ends, ensuring that players can fully capitalize on the rewards offered.
Requirements
To take part in the Help Kai Event in Zenless Zone Zero, players must first reach Inter-Knot Level 15. This requirement ensures that participants have progressed far enough in the game to engage with the event mechanics and challenges. Once eligible, players can access the event through the dedicated event menu or by locating Kai on Sixth Street, where they can begin accepting tasks.
Meeting this requirement early allows players to maximize their participation throughout the event, ensuring they have ample time to complete objectives and claim rewards. Players who have not yet reached Inter-Knot Level 15 should focus on progressing through main story quests, daily commissions, and other activities that provide experience. By doing so, they can unlock the event and take advantage of the valuable resources it offers. Since the Help Kai Event provides essential rewards such as Polychromes, Boopons, and upgrade materials, ensuring eligibility as soon as possible is highly beneficial for overall progression in Zenless Zone Zero.
How to Start

After reaching Inter-Knot Level 15, players can begin the Help Kai Event using one of two available methods. The first and most convenient way is through the event window, where a red exclamation mark will indicate the event’s availability. By navigating to the event menu and selecting the [Go] button, players will be instantly teleported to Kai, allowing them to start the event without any manual travel.
For those who prefer to explore manually, the second method involves locating Kai on Sixth Street. To do this, open the map and teleport to the Music Store. From there, head left of the store until you find Kai standing in front of a sign marked with HIA. Interacting with him will trigger the event, allowing players to begin completing tasks and earning rewards. Choosing either method ensures smooth access to the event, making it easy for players to participate and start working toward the valuable rewards offered during the limited-time event.
How to Play
The Help Kai Event in Zenless Zone Zero revolves around completing a variety of tasks to earn valuable rewards. These tasks are split into two categories: Weekly Goals and HIA Affairs, each offering different types of challenges and incentives. Players can track their progress through the event menu and work toward clearing as many objectives as possible to maximize their rewards.

Weekly Goals consist of five tasks that reset every Monday at 04:00 (server time). These tasks are designed to integrate seamlessly into regular gameplay, often overlapping with existing activities like Battle Pass missions or Ridu Weekly objectives. By completing these tasks, players can progress through the event without needing to deviate significantly from their daily routine. Common Weekly Goals include participating in Agent Invitation events, checking in at the newsstand scratch card, accumulating 400 Engagement points in Errands over three days, spending 1,200 Battery Charge, and completing Hollow Zero Operations. Since these objectives refresh weekly, staying on top of them ensures that players can claim all available rewards before the event ends.
HIA Affairs are one-time tasks that do not reset, requiring players to complete unique challenges to earn additional rewards. These tasks may demand extra effort, such as spending 100 Z-Merits at the Logistics Shop, clearing Floor 10 in the Simulated Battle Trial, defeating enemies in Bizarre Brigade at difficulty 3 or higher, or enhancing Drive Discs by 15 levels. Some tasks will also involve completing specific content, like Outpost Beacon areas in story missions or exchanging materials at Sȧn-Z STUDIO. Since these objectives do not refresh, players should aim to complete them as soon as possible to maximize event rewards.
To get started, players can visit Kai on Sixth Street, where they can access the event menu and begin tackling tasks under Weekly Goals and HIA Affairs. Completing these tasks efficiently will allow players to earn key resources such as Polychromes, Boopons, and upgrade materials, which are essential for progression in Zenless Zone Zero.
Tasks
The Help Kai Event in Zenless Zone Zero consists of two distinct types of tasks: Weekly Goals and HIA Affairs, each offering unique challenges and rewards. Players are encouraged to complete as many tasks as possible to maximize their gains during the event.
Weekly Goals are a set of five tasks that refresh every Monday at 04:00 (server time). These objectives are designed to align with regular gameplay activities, making them easy to complete alongside other in-game duties. They are similar to Battle Pass missions or Ridu Weekly tasks and provide a structured way for players to earn additional rewards. Examples of Weekly Goals include participating in three Agent Invitation events, using the newsstand scratch card twice, accumulating 400 Engagement points in Errands over three days, spending 1,200 Battery Charge, and completing two Hollow Zero Operations. Since these tasks reset weekly, players should aim to finish them before the next cycle to maximize their progress in the event.

HIA Affairs, on the other hand, are one-time tasks that do not refresh. These objectives often require players to complete specific in-game actions that may take additional effort. Some of these tasks involve spending 100 Z-Merits at the Logistics Shop, clearing Floor 10 in the Simulated Battle Trial, defeating enemies in Bizarre Brigade at difficulty 3 or higher, and enhancing Drive Discs by a total of 15 levels. Others focus on progressing through certain content, such as completing an Outpost Beacon area in a story mission or making two exchanges at Sȧn-Z STUDIO. Since these tasks are limited to a single completion, prioritizing them early ensures that players do not miss out on any rewards.
By completing Weekly Goals and HIA Affairs, players can earn valuable event rewards, including Polychromes, Boopons, and upgrade materials, all of which contribute to strengthening their agents and equipment. Efficiently managing these tasks will help players make the most of the event and enhance their overall progression in Zenless Zone Zero.
Rewards
The Help Kai Event in Zenless Zone Zero offers a wide range of rewards for players who complete Weekly Goals and HIA Affairs tasks. These rewards include valuable in-game currencies, upgrade materials, and resources that contribute to character progression. By fully participating in the event, players can earn a substantial amount of materials to enhance their agents, W-Engines, and overall gameplay experience.
Completing event tasks provides players with a total reward pool that includes 400 Polychromes, 5 Boopons, 150,000 Dennies, 50 Original Chips, 10 Senior Investigator Logs, and 20 W-Engine Energy Modules. These rewards can be earned progressively by fulfilling event objectives, making it essential for players to stay engaged throughout the event duration.
Weekly Goals offer incremental rewards for each task completed. Each Weekly Goal grants 40 Polychromes, 2 W-Engine Energy Modules, and 5,000 Dennies, encouraging players to complete all five available tasks per week to maximize their gains. Since Weekly Goals reset every Monday, completing them before the reset ensures that players can claim the maximum possible rewards.
HIA Affairs tasks, being one-time challenges, provide unique rewards that cannot be repeated. These include 10 Original Chips, 2 Senior Investigator Logs, 20,000 Dennies, and 5 Boopons (awarded specifically for clearing Floor 10 in the Simulated Battle Trial). Since these tasks do not refresh, prioritizing their completion early in the event is a good strategy to ensure all possible rewards are obtained.
Additionally, the Battle Pass system integrates with the event, offering 1,600 City Fund EXP for players who complete all Weekly Goals in the Help Kai Event. This added incentive makes event participation even more beneficial, as it contributes to unlocking further rewards through the Battle Pass progression.
By actively engaging with the event and completing all available tasks, players can maximize their rewards, gaining essential resources that will help them strengthen their roster, upgrade equipment, and prepare for future challenges in Zenless Zone Zero.
