Bear in mind, I’m a chronic procrastinator, meaning I haven’t actually done any of this in any actual capacity. But the way I see it, the way you illustrate the story is all up to you. You do eventually need all 64 Elements, but one thing I recommended in another of my posts was to start planning out the story and see where it’s not firing on all cylinders.
Like, maybe as you sketch all your characters out, you can’t find a good character to represent Support. None of your characters can really pick it up without feeling awkward, so you look at your story. Huh. There’s this scene, right here, where the Main Character is agonizing over the pain he has to bear; that’d be a perfect time for someone to Support him. What about a servant girl? She’d be nothing more than a bit part, but she’d come in to bring him some food, see him upset, and offer to listen to his plight. When he explains how he feels, she assures him that he is strong, but that doesn’t mean he has to struggle alone. And those warm words of comfort help restore his courage, and he sallies forth the next morning a stronger man. Now, of course I came up with that example exactly so I could demonstrate how to do it, but hopefully, when you look at your story, you can see it, too.
Don’t misunderstand me, though. This isn’t like Save the Cat or the monomyth where it’s gotta be exactly how it’s described in the book. The beauty of Dramatica as opposed to those other paradigms is that you can cast these Elements however you want. StC’s Fun & Games is kinda like Feeling, but in a specific way. What if I don’t want my characters to have a light-hearted moment of whimsical pleasure? Dramatica doesn’t have a problem with that; one ideation of Feeling isn’t any better or worse than any other. And the monomyth has a Guardian, but again, the Guardian has to have a specific role and meet certain standards. What if I want my character to ignore the advice of the (actually really annoying) Guardian and decide to seek help from the Contagonist instead? Dramatica says go for it; that kind of Guardian is just as Guardian-y as Joseph Campbell’s.
In the end, that’s all I or anybody else here can advise. Have all the Elements, and have them interact somehow. Hopefully, it’ll all slip together as you write.
