No, not particularly. I would imagine that you yourself have had various Courtesan Outfits in your inventory, presumably looted off the corpses of various succubi seeking your head. Adventurer's Luck and their lack of discrimination when it comes to Loot, I would suppose. I just haven't gotten around to selling that particular piece of equipment as I was side-tracked by matters. I was lucky when I was able to deal with my own adversary succubus with only my so-called "Toothpick". Imagine, a boy of 16 just starting out on his own adventure when he's suddenly propositioned by a beautiful woman. Of course, this being the start of his adventuring days, this boy not-yet-man would believe this to be the start of his very first quest chain which would end in a very magical artifact as a reward for running around the town doing various errands like taking out the local trash, finding her lucky amulet she left in the cabinet of her neighbor's hovel, or buying some groceries. Alas, imagine my shock when the woman just comes out and says that she needs me to "warm her bed" for the night. So, I promised to come back in the evening after I've procured some firewood. When I returned, I found out she didn't actually want me to warm her bed by fueling the fireplace, but that revelation came a bit too late. My memory of the events after are very foggy, but I somehow prevailed and the succubus was dead. Following the standard adventuring procedure for these incidents, I was obligated to acquire her outfit.
