The Legend of the Galactic Baseballer event in Honkai: Star Rail has offered Trailblazers a slate of multi-wave combat challenges since it first appeared, blending trial characters, stacking buffs, and roguelike upgrade choices. Among the six stages in the event, the final confrontation — Eternal Black Hole — remains the most demanding, pushing players to reach at least 60,000 points to claim every reward. For players looking to clear this stage efficiently in 2026, a solid understanding of character synergies, weapon priorities, and boss mechanics is essential.
How to Unlock Eternal Black Hole in Honkai: Star Rail
Before Trailblazers can even access The Legend of the Galactic Baseballer, they must complete the Tales from the Golden Age Trailblaze Mission. Once that prerequisite is satisfied, the event opens with a total of six stages. Each stage contains between seven and eleven waves of enemies, and players receive a series of buffs and weapon upgrades that make later fights more manageable.
To unlock the Eternal Black Hole stage, players simply need to complete the previous five stages in sequence. There is no special hidden requirement beyond progressing through the event. This final stage serves as a culmination of all the mechanics introduced earlier, so it is worth reviewing how buffs and weapon effects interact before diving in.

Once the stage is unlocked, preparation becomes the key to success. Players should consider the recommended trial characters, weapon and accessory picks, and the final boss encounter with Something Unto Death. Below are the most effective recommendations for clearing the stage with a high score.
Best Characters for Eternal Black Hole
The Eternal Black Hole stage features frequent enemy weaknesses to Wind and Lightning attacks. The following trial characters are highly recommended because they exploit those vulnerabilities while also offering strong supportive utility:
| Character | Role | Key Contribution |
|---|---|---|
| Kafka | Lightning DPS / DoT trigger | Deals heavy Lightning damage and activates damage-over-time effects |
| Acheron | Lightning DPS / debuff support | Applies debuffs and adds extra damage pressure |
| Black Swan | Wind DoT specialist | Inflicts Wind DoT that scales well against high-HP enemies |
| Huohuo | Healer / buffer | Provides healing, energy regeneration, and team buffs |
Players should prioritize teams that can stack debuffs and DoT effects. Acheron and Black Swan work especially well together because their debuffs set up powerful follow-up damage, while Huohuo keeps the team alive during longer waves. Kafka rounds out the team by triggering DoT effects immediately, creating a very aggressive damage loop.
Best Weapons and Accessories
After each wave, players can select and upgrade weapons and accessories. The following options perform well in Eternal Black Hole:
-
Nihility's Warning : After allies hit enemy targets, there is a 70% chance to inflict Chagrined. When enemies with Chagrined receive other debuffs, they gain additional stacks. Each stack increases all damage received by 0.4%, up to 20 stacks. At 20 stacks, Nihility's Warning deals Quantum DMG equal to 3,000% of base DMG, with bonus damage against Elite and Boss enemies. This weapon is exceptionally strong when paired with Acheron's debuff application.
-
Prayers of Beauty : Summons a unit with 75 SPD. When it takes action, it boosts team damage by 300%, advances all allies' actions forward by 100%, regenerates 10 Energy, and recovers 1 Skill Point for 1 turn.
-
Rainbow Bat : After an ally attacks, Rainbow Bat deals 4 hits of random-type DMG to a random attacked enemy, each equal to 100% of base DMG. Damage increases by 30% against Elite and Boss enemies.
-
Thunderbolt Thorns : Applies a Lightning DoT to an enemy. At the start of each turn, the target receives Lightning DoT equal to 400% of base DMG, which bounces 3 times for 50% of the original damage per bounce. When the initial target is defeated, the effect transfers to a new target.
-
Ranger's Longbow : After an ally uses their Ultimate, this accessory fires 3 Wind Arrows. Each arrow deals Wind DMG equal to 300% of base DMG to a random enemy, plus 25% AoE DMG to adjacent enemies.
-
Me for Everyone : Increases SPD of summon-type weapons by 30.
Among these, Nihility's Warning stands out as the top priority in this stage. Because Acheron naturally inflicts debuffs, the weapon reaches its maximum stack potential quickly, resulting in massive burst damage. Players should also consider Ranger's Longbow and Prayers of Beauty as strong secondary upgrades.
Strategy Tips and Boss Guide
Before starting the stage, players should invest Raccoon Tokens into all available upgrades at the Cosmic Store to maximize base stats. If additional tokens are needed, replaying any already completed stage is a fast way to farm them. Players can also use the refresh button at the start of the stage to shuffle the enemy lineup, which can make early waves significantly easier depending on team composition.
The final boss of Eternal Black Hole is Something Unto Death. During this encounter, the boss can immobilize allies at certain points, preventing them from taking actions. To counter this, players should grab any weapons or accessories that trigger automatically after an Ultimate is used or have an automatic launch effect. These passive damage sources continue to apply pressure even while the team is locked down.
Some of the best choices for the boss fight include Ranger's Longbow, which fires after ally Ultimates, and Rainbow Bat, which reacts to any ally attack. Prayers of Beauty also helps by advancing the team's actions and restoring Skill Points, giving players more opportunities to break out of immobilizing effects.
Players who stack automatic-trigger weapons, invest in Cosmic Store upgrades, and build around Kafka, Acheron, Black Swan, and Huohuo should be able to surpass the 60,000-point mark and claim every reward from The Legend of the Galactic Baseballer event.
