I think u should start with 10 re-rolls and that's it, there should be no way obtaining more other than events or a system called amnesia causing u to re roll every like names, traits, and some mastery of things to an extent. With a system of things you can use call mementos that allow you to not re-roll some things. Once you roll some things enough times like 50 you will have the choice to return to it with a really hard quest. It won't require a super high level to acquire the means to use amnesia just a quest or a rare material. This will stop players from having OP build from the very beginning and also add a lot of game play time.
Quick side rant pls add fan made breathing and blood demon art and make breathing have strengths and weaknesses based off what they derived from and the blood demon arts having moon level where it has more or less weakness based on the level the moon is randomized with the same ability with one or two bonus ability if you get lucky or work for it to a hashira or upper 3 level. This will bring more variety and not let the options feel stale. This for hinokami
