Honkai Star Rail Key of Knowledge Guide: Introduction
The Honkai Star Rail Key of Knowledge is a powerful 3-star upgrade material with significant utility in leveling up Erudition characters and ascending Light Cones. Revered as a “mythical key” that appears only in the hands of sages from various worlds, it holds a profound connection to unlocking the mysteries of existence. Despite its importance, its form is said to remain invisible to all except the wielder, adding an air of mystery and speculation surrounding its true nature and origin. This enigmatic artifact is used to level up Traces moderately for a select group of characters, including Argenti, Herta, Himeko, Jing Yuan, Qingque, and Serval, as well as to ascend numerous Light Cones tied to the Erudition path.
The Honkai Star Rail Key of Knowledge can be acquired in multiple ways, making it relatively accessible for players who know where to look. One method is to conquer waves of enemies in the Calyx (Crimson): Bud of Erudition, located in Rivet Town. For those with more resources at their disposal, the Omni-Synthesizer provides an option to convert materials, where three Key of Inspirations can be synthesized into one Key of Knowledge. Additionally, it can be purchased from the Deep Web Gray Market and the Embers Exchange for 18 Undying Embers, though the latter option is restricted to players who have reached Trailblaze Level 30, with a monthly purchase limit of 30.
This upgrade material is essential for progressing certain Erudition Light Cones, as it plays a pivotal role in ascending 12 Light Cones such as Data Bank, Sagacity, Make the World Clamor, and The Birth of the Self, among others. These Light Cones are critical for boosting the capabilities of Erudition characters, making the Honkai Star Rail Key of Knowledge invaluable to those looking to enhance their squad’s performance. As the item aids in the ascension process for both Traces and Light Cones, players will need to strategize their collection efforts carefully to ensure they have the resources necessary for optimal progression.
While no character directly utilizes the Honkai Star Rail Key of Knowledge for their own ascension, its influence cannot be overstated. From improving character Traces to enhancing Light Cone abilities, it serves as a crucial part of the resource ecosystem. The Key’s versatility extends further, as it can also be used in the Synthesizer to convert into other Trace or Light Cone Ascension Materials, giving it an essential role in the progression of many characters. With its ability to level up Traces “slightly” or “moderately” depending on the source, the Key of Knowledge remains an indispensable resource for players looking to maximize the potential of their Erudition-focused heroes.
