Fair this is largely my head cannon for playing a holy whore
After thinking about the most practical way to have stats for the armor would be something like
The armor pieces all have CON boosts to give a reason for non succubus players to obtain so for example if you want to mix and match with the leather set for more carry weight for trap and bomb making or mix and match with the adventurer or footman set to be a pseudo paladin with the extra tankiness
Then each piece gives bonuses to specific sex attacks
Acc- Nun Vail gives a bonus to Oral skill
Top- Coif and crucifix that gives a bonus to Hand skill
Mid- Tunic gives bonus sexy or perhaps reduces aggro generated from acolyte skills
Bottom- Revers chastity belt gives bonus Vaginal skill and cannot be removed without either True Deepone transformation or paying someone
Mid extra- Mantle gives bonus Anal skill
Or some other kinda bonuses to sex related abilities and/or relic weapons
Repentant/flagellant armor that give bonuses for having wounds would also be cool for a glass cannon build though that's probably a different subject
