Done some more testing with Dragon's Crown and as it turns out, everything works for every character in every slot. I don't really need to do anything with my previous codes. I don't know why I kept thinking everything was class specific or character slot specific. From what I've tested so far my Infinite HP works for different classes and character slots. The custom Equipment mod is the same and works perfectly for every class and character. So I guess I really did confuse myself all this time.
Anyways I did some more digging and I was able to make custom equipment mod for Allies(party members) equipment as well. These codes however are indeed based on Allies created first and since you can have 30 party slots, I'm not really sure how to make these code fit properly inside vita cheats. Since party members are randomly generated, each party member can have different items in their bag and a lot of them don't even have 9 slots in their item Bag so I can't really make an all Bag code, I could but I really don't know the effects of using these codes with consumable items in the way or few slots, so its best to edit 1 equipment slot at a time, per Ally. Its not the best option but its still kind of neat.
Sadly I'm too lazy to work on more Ally slots and equipment slots, its just too much. There's a lot you could do with custom equipment codes but since vitacheat it limited on space, its just easier to add your own. Ally slots increase by 23AC(in hex) so just keep adding that to the address to get your Ally slot
Code:
85C035D0 + 23AC = 85C0597C
.
For the next equipment slot just add 54(in hex)
Code:

Also a little bit about this code and your main character equipment mod is these codes only work in the hub town after you leave the tavern. From what I noticed in my dumps is your party members addresses aren't generated until after you leave the tavern with your Allies in your party so that's when you should use the codes. Whoever you take with you outside the tavern, you need to make sure the codes you have are for them. For example you use a code for Ally slot 4 when you only have Ally slot 1, 2, and 3 in your party outside the tavern, the game is probably going to freeze since slot 4's addresses hasn't been generated.
Lastly I wanna make an mana code and a new arrow code so I can be pretty much done with this game.
