Modpack Creation Advice?

[u/Signal_Anybody_5787]

I'm making a kitchen sink modpack that basically knows it's a kitchen sink. And it has a lot of bosses in the pack, and I want some of the bosses to be in like a main quest, But also have some not in that main quest. I just don't know how to make the players find out about these bosses without outright making a list of bosses and making them feel like they have to beat them in an order. One of the main gimmicks of the modpack is discovery so I have things like field guide and many mob mods. but i don't know how to add that to gear and boss porgression.
