If you want to have the "best" character possible, you really need to spend way more than 300m.

To get the best possible, you need to get +10 set and weapon, 28%atk suit, the best possible awakenings on all your equipments and pet, perfect s rank pet, 10 piercings on your weapon, 10 A level cards on your weapon, statted mask and cloak, +20 jewels. To get all these would cost way more than 300m, but would get you the best possible character for you.
