I was considering trying to make a mod of a handful of either flavor mutations or other mutations that I think would be somewhat interesting. Before I start though, my main question would be this: Is it possible at the moment? Can I just add in a new mutation, or will I have to recompile an executable myself? Because I don’t want to really go through the trouble to do that if I can’t just do it in the JSON files.

Yes you can add mutations. But not all features of the mutations are json values. In fact quite a lot of them are hardcoded.

I tried to update some of the mutations json documentation recently. (see these changes: [https://github.com/CleverRaven/Cataclysm-DDA/pull/18062/files](https://github.com/CleverRaven/Cataclysm-DDA/pull/18062/files) scroll down for the JSON\_INFO.md file). The only thing missing is the documentation about the attacks. (Look at the other mutations for how those work).

Alright! Thanks for the answer. I’ll take a look eventually. See if I can do what I wanna do without having to compile it myself.
