I'm sure that there are other fetish/job combinations that will give affection gains and money. Half the fun is experimenting with enchanting items and customizing your slaves.
I went through the pain of making five imported characters, each one a elemental (fire, earth, wind, water, & arcane) only to figure out the max party limit was 2 people. A summoned elemental by you doesn't count, apparently, so you can have 3.
Also, by "pain", I mean getting them legit names (Salamander, Gnome, Sylphine, Undine, Octavia I'm not original lol) and maxing out some certain stats as well as outfits fitting them (like a androgynous butler build for Gnome or a kimono set for Undine).
aaaaaaaaaa
