Recently I got curious and started to hack Fire Emblem: Three Houses with decent progress so far. After doing some basic stuff like hacking growths and bases I created a Nightmare Module for editing character skill tables. I’m probably going to develop more modules in the future. I also created a Github Repository to share my work.
Edit: Huge Update. A standalone tool is now available.
This tool will be updated in the future to add more functions. For now it features a fairly powerful character editor and the first release is available on Github.
You can edit bases, max stats, growths, spell lists, crests, learned skills and more.
For the next release I will add a class editor and a basic randomizer tool.
