How to reach Eidos 9 in Stellar Blade and unlock Secret Battles
Eidos 9 in Stellar Blade is a hidden area filled with epic fights and rare rewards. But reaching it takes effort. If you interact with Adam too early, you will miss your chance. Here¡¯s how to get 100 percent data progress and unlock this secret spot before moving on.

Eidos 9 is a secret area in Stellar Blade that you can only access if you meet one important condition. Many players miss this location because they move ahead in the story too fast. But if you want to unlock everything the game has to offer, including hidden fights and rare rewards, you¡¯ll need to take a small detour.
Eidos 9 is tied to Lily, one of the key characters in your journey. You¡¯ll first hear about it during your mission in Abyss Levoire. But unless you hit 100 percent data progress with Lily, you won¡¯t be able to visit the location. Instead, the game will send you to Orbit Elevator or Spire 4, skipping Eidos 9 entirely.
So before talking to Adam to move the story forward, make sure you¡¯re fully prepared. Here¡¯s how you can unlock Eidos 9.

To access Eidos 9, you need to complete Lily¡¯s data log to 100 percent. This includes collecting every memory stick, document, passcode, data slate, and other hidden items tied to the mission and the Truth of Mother Sphere. You can track your progress using the percentage bar that appears in the top-right corner of the screen during the mission.
Take your time before ending the Great Desert chapter. Explore every corner, scan the environment, and pick up anything that can boost Lily¡¯s data records. If you¡¯ve missed something, go back and grab it.
Once you¡¯re sure that the bar shows 100 percent, interact with Adam. This time, Lily will stop the squad and mention Eidos 9. That¡¯s your cue to head there.
Eidos 9 is also where Lily¡¯s atelier is located, and the area offers strong enemies and good loot for those who like tough challenges.
Keep in mind that after you arrive at Eidos 9, you won¡¯t be able to go back to Xion City. So it¡¯s smart to finish all side quests from NPCs and gather whatever you need before moving forward.
If done right, unlocking Eidos 9 adds an exciting new layer to your Stellar Blade journey, with more battles, better gear, and a deeper look into Lily¡¯s story.
