Describe your idea, include images if necessary

Well... I would think it would be cool to be able to edit the Traits, Powers, Life, etc... Of a mob that has nothing, for example: A mob from a mod, I would like to be able to edit the attributes that it will give when I defeat it and have it in my Morph Menu, I don't know if this is possible, or if you don't think it's cool, but it would be interesting, it would be incredible and it would make the mod more interesting to be able to add things to mobs that could have something, but don't. (Note: I'm Brazilian and I know a little bit about English, I'm using the translator to type).

Hey! You can already edit the traits, abilities and variants via data packs (I've linked the corresponding wiki links).
Note that these wiki guides require a bit of data pack knowledge, you can watch a YouTube video on how to get started with creating data packs.
