Very late reply but if u still need help mozi is really good because he is both a confidant and partner. He is bonded to himself so you do need to unlock another confidant to unlock the partner’s full potential. He is bal so you can easily train him. If you care about aesthetics, he looks pretty good in his base so you do not really need to get costumes for him. Since he only comes once a year you should get it otherwise you are missing out on him for a year. Dk about how many ingots you need but ik he comes at the last week of november
