Celebrate the third anniversary of Honkai: Star Rail with our comprehensive Cosmic Data Roaming event guide! Learn how to maximize your streamer level, unlock powerful character slots, defeat difficult chapter bosses, and claim the exclusive 4-star Light Cone alongside 1,120 Stellar Jades.

The third-anniversary celebrations for Honkai: Star Rail have reached an all-time high with the introduction of the highly anticipated Cosmic Data Roaming event. Running from April 22 to June 1, 2026, this massive Version 4.2 streaming event tasks Trailblazers with stepping into the shoes of a galactic broadcaster. By streaming the epic journey of the Astral Express, managing audience hype, and strategically upgrading a virtual combat lineup, players can earn some of the most lucrative rewards of the year. This comprehensive guide will walk you through every stage, combat power requirement, and mechanic needed to conquer the virtual leaderboards.

📡 Initiating Your Cosmic Data Roaming Stream

To dive into the streaming action, players must first meet the baseline requirement of reaching Trailblaze Level 21 or higher. Once unlocked, the core gameplay loop revolves around managing resources to continuously upgrade your broadcast's combat capabilities. During your streams, you will actively collect Diamonds from viewer gifts and stage clears, which are then used to draw new characters for your virtual lineup. Simultaneously, you will earn Gold Coins to level up your team slots, boosting their baseline stats.

Unlike traditional combat events, Cosmic Data Roaming incorporates a highly rewarding idle mechanic. Trailblazers can step away from their streams and accumulate offline rewards over time. Upon returning, you will find a massive stockpile of Crystal Orb Chests, Diamonds, and Gold Coins waiting for you, ensuring that you can constantly upgrade your team's equipment and star levels even when taking a break.

⚔️ Navigating the Chapter Bosses and Mechanics

The event is structured across six main chapters, each introducing new gameplay mechanics and requiring significantly higher Combat Power (CP) to defeat the final boss. Your journey begins at the Herta Space Station, where you must achieve a minimum CP of 38,000 to defeat the Starcrusher Swarm King, Skaracabaz. Progressing to Jarilo-VI introduces the Basic Talent tree, allowing you to spend Talent Points on crucial team boosts while managing interactive viewer messages that alter stream outcomes.

As your channel grows, the challenges scale aggressively. Reaching The Xianzhou Luofu unlocks the Raid feature, allowing you to farm specific resources while working towards a mandatory 1.25 million CP threshold. The Penacony chapter forces you to prioritize drawing duplicate characters to upgrade their star ratings, pushing your team past the 2.70 million CP mark to overcome the Swarm Nightmare. Upon arriving at Amphoreus, you will unlock the Chrysos Heir Assist feature, granting an extra support slot necessary to hit 5.20 million CP and defeat Zandar. Finally, the ultimate challenge awaits in Planarcadia, where you must utilize the Level 6 Banner to assemble a team of 5-star characters, max out your slots to Level 80, and achieve a staggering 6.20 million CP to defeat the Alloy Mechatron King Pom-Pom.

💎 Exclusive Event Rewards and Objectives

Successfully managing your stream and clearing all six chapters yields an incredible haul of anniversary resources. Players who consistently upgrade their setups and interact with their chat will walk away with an abundance of premium currency and exclusive gear.
