So I'm new to modding DD and I'm trying to figure out if there's a way to add a unique version of the file that houses all the core trinket information.

I know something like this is possible since I've seen custom class mods use things like "customclass.camping_skills.json" with only the relevant new code instead of altering the core "default.camping_skills.json" and the game is apparently reading it just fine since it all works. However when I try to do this same kind of thing with base game's "base.entries.trinkets.json" and have my own "phiore.entries.trinkets.json" file I'm not seeing my trinkets show up in game.

I could be really unlucky and just haven't seen the damn things but I get the feeling they're not loading in properly. Does anyone have any experience with this kind of thing? I'd really like to have my custom trinkets not conflict with future updates/overwrite the base game's file.
