Can you make a cheat that when each level up all the abilities increase +1 except only MOV? because CHARM also increases itself on natural level up.

So is it guaranteed that my game will crash if I put two or more house leaders in the same team? I'm currently on BL route and I really want to have Edelgard and Claude on my team for the last two battles, just for fun.

How to get playable NPCs into your save with save editing:

  1. Export a character that suits the character you're trying to change it to (you can't have all proficiencies be S or S+ when editing units normally, If you want for example a Rhea that uses Magic, just export for example Dorothea or any other magic unit and change the ID like usual) using Falo's save editor
  2. Edit the .character file that comes out of it with HxD hex editor
  3. Press Ctrl + G and go to offset 24, there you should find the character ID
  4. Use the Test -> CharacterDB section of the save editor to find your character ID (The ID's are basically the same as you think just subtract one number, and convert it into hexadecimals <https://www.binaryhexconverter.com/decimal-to-hex-converter> like for example Jeralt's ID is in hexadecimals 23 but in decimals it is 35,) just type in the ID into the offset, and you're all set!

im sorry @hanseo , nearly didn't even see this .. sometimes it's better to ask again or send PM in case i missed it ,
but anywho i send to you in a sec. would u rather have by PM or in Chat?

So is it guaranteed that my game will crash if I put two or more house leaders in the same team? I'm currently on BL route and I really want to have Edelgard and Claude on my team for the last two battles, just for fun.

and yes it is guaranteed more or less..
-(One House Leader - Per Squad for story-Claude-Golden Deer, Dimitri-Blue Lions, Edelgard-Black Eagles )
To what I've Gathered and whatnot , this Seems to be the Case although I'm Early Progress in the Game right now, so i Can't Completely say for sure ,
but to a lot of others that have beat the game and stuff , they said this is the Case

No u can not do that Normally.. it will crash game.. -far as i know -- it's *Hard-Coded* into Game meaning only a Mod** Could Change that... Although..
i heard there Can or could be Special Code(s), but this would be a Major Code(s) , and also probably would also need a special *Master-Code* to Enable this .. if it was done..
i've seen this before, possibly could be done , but it would take a really *Well-Experienced Hacker and or Modder* to do this by *Code Alone..

i Can't even get a Convoy Code lol and that's nothing compared to what your talking! :P
I'll be honest with you , as of right now, this will not happen .. just wait for a mod to be released for this one..
Although the save editor may be able to do this though just for *in-battle* only?.. have u tried it yet?

Done more testing with the editor, primarily regarding saves and character recruitment so as to answer some burning questions.

First, characters - I've had quite varying results, however the most consistent was the game was the house leaders being on the same team as this crashed my game 9/10 times if just adding them to the team via the editor and not messing with values. Retainers have been somewhat iffy, since I've grabbed Dedue on a BE run and had no issue up to a certain point, which is a problem that has repeated a few times with the other retainers but does not occur as consistently - sometimes the game just crashes minutes after loading the save, sometimes hours or not at all.

Secondly, saves in general. I wanted to see if I could replicate the issue I had prior with saves skipping certain parts of the game if you overwrite one slot0x file with another edited slot0x file, and again I had rather varying results, which will be in no particular order;

- Depending on what phase the save is in (Battle Prep, Battle Selection, Monastery, Free Day Choice Screen, etc) there seem to be different outcomes - sometimes nothing happens, sometimes scenes are skipped or the save just melts down. The most recurrent one I had was overwriting a save with another that had been edited while at the Battle Prep screen, and when loading it had skipped the fight entirely. I managed to replicate this at least 4 separate times in 4 separate battles, and even on different saves.

- Character Class Flags. Sometimes, and by this I mean it happened maybe twice in the 200+ save edits I made during testing stuff, a character that has had a class added via ticking a flag in the Class Flags tab has said class locked out permanently. I have literally no idea as to why this occurred, however both times I was in the Monastery. Aside from this, everything was mostly fine aside from odd crashes when adding unique character classes to characters that do not have them via normal means (eg giving Lord to Caspar caused two crashes, but rather far apart - happened on all characters that do not get it naturally and occurs with all * classes on occasion from testing).

- Autosave File. This was something I was apprehensive about touching just in general because well, its the autosave. As expected, the issues would all occur on the autosave the same as the regular slot0x files, however at some point my switch nearly bricked itself when loading from the edited autosave during testing - gonna leave editing it alone for now, but it was probably me being an idiot somewhere along the line.

I'll keep going to have a look at what else I can get this thing to do. Also @Zaybokk , could I possibly get (via PM) a list of the general cheats you've managed to make aside from the ones currently available in the public cheat file so I can have a go with them? It just gives me more stuff to strain saves with in the end.

The maximum for Skill Rank is S+, although I don't know why you'd only want a skill to go to A and not all the way to S+ (the bonuses are sometimes pretty darn good). However, to each their own - I just rank the skills up to S or S+ with a quick toggle of x256 during a mission if the character is a class that levels in the skills I want.
