You want to be looking at the values of the HEALTH, PHYS/MAG, HEALING to the left in the character of your choice’s Growth tree screen (Doesn’t work for defence at least to my knowledge there’s no way).
Be sure to have enough pieces to upgrade at least one node of the stat you wish to change/upgrade.
Look at its current value, say for example strengths current is +25 and you wish to alter that, put 25 into CE with 4 bytes/exact value, then purchase the node to increase that value, now say it’s gone up to +32, put 32 into CE and next scan it.
You should get 1 result most of the time if so save/move that address then change the value to what you wish and freeze it (click box to the left of address and it’ll give you a Red Cross inside).
SIDE NOTE: If for some reason you get 2 results, choose the one which value isn’t changing constantly, or try again.
This should have taken effect, now before you go into a solo battle at the party prep screen just press recommended and you’ll see your characters power adjust and you’re now off the the races.
I have heard it isn’t effective in dungeons and I’ve not bothered trying myself since hearing that but any single solo battles work.
Now get yourself an auto clicker and go to town farming.
