Yeah it took me a while to find a lot of the relevant info. On speedrun.com I've tried to compile a guide with a bunch of info about how the RNG works, most of which I've learned from japanese speedruns, very old threads on here about japanese speedruns, talking to people, and experimenting myself.

Like I said, if you have less than 10 skill the game will pull a random number for the staff hit, but if you have 10 skill, the game doesn't do that. If you don't roll a number for hit, how can you miss? It may be the case that if you leave animations on the displayed hit is 99 (I never leave animations on for staves so I wouldn't know) but after screwing around with Thracia RNG manips for months I know that the above is actually how the game works.

Actually as long as a staff user has 10 skill healing staves never miss, the cap is 100%. The game won't even roll the number. As a speedrunner I actually enjoy the fact that staves can miss because it provides an opportunity to get weapon XP without losing staff uses. I imagine the max hit being 99 for regular attacks isn't just a big middle finger to the players, but a way to make characters in cutscenes invincible without any contradiction in game with the combat math. I like the holy blood in fe4 but I think if it's going to be implemented in the future it should be more like crusader scrolls. Being able to make your characters more like certain crusaders in each chapter is a bit more of the kind of micromanaging I like than trying to manage inheritance optimally.
