Imagine the delight of possessing a library brimming with a vast array of books, ranging from mundane tomes to mystical volumes of eldritch wisdom. However, the arduous task of safeguarding and relocating such a collection can be overwhelming. With this power, you not only gain an inherent encyclopedic knowledge of all 103,000 magical books of eldritch wisdom, but also possess flawless indexing of your memories and knowledge. This enables you to effortlessly retrieve information from your mind whenever needed. Additionally, you acquire a subconscious ability to analyze and gather information or data through your senses. When confronted with problems or questions, your conscious mind cross-references them with your knowledge and memories, providing you with precise answers of uncanny accuracy.
Furthermore, this power grants you resilience against mental poisoning caused by exposure to eldritch truths, reducing their harmful effects to a negligible level or minor inconvenience at most. You also develop resistance to creatures or events that induce insanity. The encyclopedic knowledge you possess continually updates whenever you venture into new worlds, endowing you with knowledge and information from all stored mundane, science, and magic related knowledge that ever existed, no matter how rare or unique they may be.
