@Vicwaberub Welcome to the community. What you describe is a very specific usecase. It can be handled with TW, but as you described. – Not out of the box.
See: Tiddlers having many roles, types and uses - #17 by intrinsical for an example wiki, that describes how to handle D&D information. But I think @intrinsical is the right person to talk to about the structure that is needed to manage all the info.
IMO you may download GitHub - intrinsical/tw-dnd: A TiddlyWiki designed to support running or playing Dungeons and Dragons 5th edition games. · GitHub and let your preferred LLM analyse the structure, that is used there and how the templates are structured.
