The Final Callback Event Guide - Zenless Zone Zero (ZZZ)Version 2.0 - Phase 1

The **Final Callback** event in *Zenless Zone Zero* (ZZZ) Version 2.0 is a recurring Audition Stage Event where players can trial featured Agents in combat demos and earn rewards. Below is a concise guide:

### Event Overview
- **Duration**: Phase 1 of Version 2.0, starting after the update (exact end date not specified but typically aligns with banner phases, ending around June 23, 2025).
- **Requirements**: Reach **Inter-Knot Level 15** to participate.
- **Description**: Players can test four featured Agents—Yixuan, Astra Yao, Pan Yinhu, and Pulchra—in curated combat trial stages. Completing these stages grants rewards and allows players to experience rate-up Agents before pulling for them.

### How to Participate
1. **Access the Event**:
- Navigate to the event menu or Hollow Deep Dive (HDD) system in-game.
- Select **The Final Callback** to enter the trial stages.
2. **Complete Trial Stages**:
- Use the provided trial Agents (Yixuan, Astra Yao, Pan Yinhu, Pulchra) to clear combat stages.
- Stages are designed to showcase each Agent’s abilities, with enemies tailored to their strengths.
3. **Claim Rewards**:
- Rewards are earned upon stage completion and can be claimed via the event page or in-game mailbox.
- Additional rewards may be available for completing specific challenges or all stages.

### Rewards
- **Polychrome**: For pulling on banners.
- **Materials**: Includes Dennies, Investigator Logs, and other resources for Agent or W-Engine upgrades.
- **Event-Specific Rewards**: Vary by stage completion and may include Boopons or other items.
- Specific quantities depend on stage difficulty and player progression.

### Tips
- **Experiment with Agents**: Use the trials to test Agent playstyles (e.g., Yixuan’s Fire Stun or Pulchra’s abilities) to decide if you want to pull for them.
- **Optimize Team Compositions**: Pair trial Agents with your own to maximize synergy, as stages allow mixed teams.
- **Focus on Objectives**: Some stages have specific goals (e.g., time limits, no KOs). Adjust strategies to meet these for bonus rewards.
- **Check Rotations**: The featured Agent roster changes with banner phases, so complete stages before the current lineup (Yixuan, Astra Yao, Pan Yinhu, Pulchra) rotates out.

### Notes
- The event is ideal for free-to-play players to test high-rarity Agents without spending Polychrome.
- Pair with other Version 2.0 events, like **Special Cleanup – Triple Bounty** or **Golden Proxy Awards**, for efficient resource farming.
- For detailed stage guides or Agent-specific strategies, check in-game notices or official ZZZ resources.
