Data Bank Completion Guide

Achieve full Data Bank completion in Honkai: Star Rail. Guide yourself through collecting all necessary entries and filling your archive.

The Data Bank in Honkai: Star Rail serves as a repository for all the lore, character profiles, enemy information, and item descriptions you uncover throughout your journey. As of the 2026 updates, achieving 100% completion in the Data Bank is a significant undertaking that requires diligent play across all game modes. This includes not only progressing through the main story quests and character companion missions but also engaging with side content like the Simulated Universe, Forgotten Hall, and even the daily assignments. For example, to unlock the full entry for the 'Stellaron Hunter Kafka,' players must not only encounter her in the story but also potentially defeat her in specific challenging encounters or read all related lore entries found in various logs and terminals scattered across planets like Xianzhou Luofu. Enemy entries are typically unlocked by defeating them a certain number of times, with tougher foes like the 'Doomsday Beast' requiring multiple encounters in challenging content like the Echo of War. Item descriptions are filled by obtaining and using various materials, from common 'Trash' items to rare Light Cone materials like the 'Stellaris Jasper.' A key mechanic for Data Bank completion involves interacting with specific lore objects in the game world, such as the 'Ancient Records' found in the ruins of Jarilo-VI or the 'Xianzhou Archives' on the Luofu. Some entries are also tied to specific achievements, meaning that completing certain feats, like reaching a specific Trailblaze Level or clearing a difficult stage in the Pure Fiction mode, will automatically unlock associated lore. make it a habit to revisit their Data Bank regularly to see what entries are still locked and then strategize their gameplay to unlock them, often by revisiting older areas or focusing on specific enemy types or content.
