Blood Memory

You infuse your own blood with a powerful divination spell, allowing you to recall distant memories or knowledge. While the spell is active, you gain proficiency in one skill or tool of your choice, as well as the ability to recall information about a specific topic related to that skill or tool. This information could be something you have heard or read in the past, or even knowledge that you have learned through a previous use of the spell. The DM determines how much information you are able to recall, based on the relevance and complexity of the topic.
