Build for any race (works well with Fairy but Human will work too)
Charisma 6 Sex 6 Starting Class Healer (choices are limited)
First servant I choose generally a Dark Elf for the Druid Class but any race will work. Your MC is on front line the others on rear. Have you noted that, for the moment at least you can have a Futa Warlock Witch?
+100% mana trait and Curious sexual trait for both. Add an extra master room to the manor and make other watch and hope they gain Curious.
After that 2 paths for the MC
Evasion Master (Thief you always need one for treasures, Rogue, Assassin) Daisy as a bard for the Increase Evasion Skill) Light Mastery because there's a skill that increases Evasion, Advanced Medium Armor with Air Crystal. Most monsters will miss you.
Lust Drain (Harlot, Succubus) Lust Drain is wonderful for free XP and Mana Drain). You need an Aphrodisiac Factory. Somebody on grain production, somebody on alcohol production, somebody permanently in Elven Capital (for flowers), and an Alchemist on Aphrodisiac Production. Hundreds of free XP every day. Every slaves in my game have these 2 classes.
I like the Apprentice, Caster, Dominator arc for Mind controller path but it's for flavor.
My first pick for MC is always +1 social skill use because it adds 1 Lust Drain use and 1 Double XP for the day use too.
