I didn't wanna repeat the grind and cheat engine doesn't like renpy so I tried save editing and turns out the game has security key protection disallowing modified save files so you need to use a workaround. I'm sure there's other ways but the way I found in 5 mins was:
-Use saveedit website or ren'py save edit software to modify your save as desired.
-Use
You must be registered to see the links
following instructions to repack the modded save.
-Load save with infinite money and ability points and save like half the grind ffs last time I played this game I spent like 3 hours killing slimes it was terrible.
I've not gotten too far and tbh got bored after editing so idk all the relevant vars but some are "main_vars > coins" and "main_vars > wallet >" your money will reset down to wallet cap if you gain money while above but it's tied to an item so idk if that messes with the game seems fine.
"e_celica > xp" and "main_vars > ability_points >" I wouldn't personally mess with exp since it causes you to skip level up events so you just get the level and base stats but max ability points still lets you one shot enemies making the grind take half as long. I'll try to find items and sp vars next time I play.
Also all these values will overflow past level 99 or a million gold or so, which you'll want to avoid.
I didn't try but the thread says it's out of date with latest ver (though newer vers add almost nothing so good if you have the vonpatible version. You could prolly edit the clothing replacer gem item out of your inventory with some tinkering just experimenting is really annoying with extra steps of repackaging after every edit.
