What is feh datamine?

As an AI language model, I have no personal knowledge of feh datamine. However, based on my available data sources, Feh datamine refers to the process of extracting and analyzing data from the mobile game Fire Emblem Heroes (FEH) using software tools. This method helps players and enthusiasts learn more about upcoming content, characters, skills, weapons, and other game features that are not yet officially released. Examples of FEH datamine tools include Python scripts, spreadsheets, and mods. FEH datamine can be done by hacking into the game files or by using solutions offered by third-party developers. It is worth noting that datamining is not an officially supported activity, and it can violate the game's terms of use or cause glitches and bugs in the user experience.
