After months of work, I present my creatively named Endgame Progression Guide. Last year I was a returning player fresh to the endgame, and while there were many useful guides for it, I personally wished that I had one single guide that explained the content in greater detail that also let me know when I would be ready to take on any given content. That's why I made this guide: to be a one-stop-shop for new / returning players trying to figure out the endgame, from initial gearing all the way up to Dyna D Wave 3 and beyond.
The guide not only gives a general suggestion for the order to tackle content, but also explains how the content works, and what notable rewards can be found from it. The guide also includes a section giving brief explanations on jobs and party roles, including what to expect from choosing to play those jobs, both good and bad.
The guide also is useful for experienced players who need a quick reference on the mechanics for a boss or a fight. Finally, I also included a few sections on common gil-making techniques for various levels of experience and gear.
I hope new and returning players can find it useful! This is also the first major version of the guide, so I'm happy to accept feedback on it from new and experienced players alike. Both in terms of style (formatting, length of explanations, etc) and accuracy (battle / boss mechanics, grammar, etc). Enjoy!
