In-depth video tutorials on how to create custom classes for BG3?

[Kantorock]

Osiyo, everyone.

Kantorock here. I'm that orange cat with that annoying voice, who until recently was uploading Cyberpunk mod reviews on a daily basis. After taking a break over the holidays, the BG3 bug bit me, and I found myself diving back into the game. Having digging around Nexus and other sites, I have come to the conclusion that no-one has created a character class or sub-class that I'm truly interested in sticking with for a long term, end-scene, roll-final-credits game.

So, I got a question: Does anyone know of a good, in-depth video tutorial that teaches a person how to create a custom starting class and sub-class for the Player Character?

I'm looking to create my own character class, starting from the bottom up, but I cannot seem to find any reliably thorough video tutorials on how to create said class. They never explain why I need to alter this line of code. They never tell me why I need to download this program, or what it does. They don't show me how to manipulate the number of cantrips a wizard gets at Level 1. They don't show me how to create a new Warlock pact. They don't instruct me on how to alter what level the class gives feats.  They don't go into the class' hit point dice, their proficiencies, or how much experience it takes for them to level up. They don't go into how to create a new spell for a Sorcerer. They don't even bother showing how to alter the starting gear.

While I am aware there are separate tutorials out there that explain how to do those things individually, I have not come across any tutorials that - in a sense - combines these instructions into an in-depth guide on how to create a custom class that touches on all aspect of what makes a class a class in BG3. All my attempt at finding such a tutorial video that goes to these lengths to take the time of explaining how to create a custom class - not just breeze through in ten or less minutes, mind you - have resulted in reviews for the class mods that have already been released. While I use a number of them, with the Dimension Traveler and Way of the Force currently being my favorite, I wish to create my own. Yet, I find myself incapable due to the dearth of documentation - primarily video, but also textual - on how to do that, and a wealth of reviews for the ones that current exist.

So, I will beg my question again: Does anyone know of a good, in-depth video tutorial that teaches a person how to create a custom starting class and sub-class for the Player Character?

P.S.

Being a visual learner sucks. Wish I could learn by reading and imagining, and not watching and mimicking.

P.S.S.

Oh, please do not point me towards the tutorials by "I'm A Doctor Not A" over on YouTube. I have already watched them. They are not in-depth, leave out a lot of information, skips steps, and tends to assume their watcher already has prior knowledge of things and why they are needed and/or how they work.
