@maestoso That's actually why I made this. I wasn't happy with the wiki page (more specifically how annoying fandom pages render and control in Big Picture mode), so I made this using the in-game information as a reference (it's all in the Battle Book, which made it really easy to just home-button between the two). Originally, the first five were in three different categories, but I later edited it down so that it would all be visible at once. I'm glad you like it. I MAY edit in the difficulties later, but when I made it I was more concerned with farming using the Rita-Spams-a-Lot method (which - for those who don't know - is where you set Rita to minimum damage, have everyone else do nothing but taunt, go into overlimit, and spam the spells that push the FS result you want), so it was rather irrelevant.

I've been using the wiki page [aselia.fandom.com], which also includes the difficulty of different colored fatal strikes against each type of enemy.

Your guide is a bit easier to read at a glance though.

Good reference, cheers.

@Bill This IS explained in game. Check the Battle Book. You got it in Deidon Hold. I literally just made this so I could press the steam button mid-battle and check which one I needed to do to get what I want.

There's so many unexplained combat mechanics like this and guard explosions in the game.
