Brothel (location)

The Brothel is an institution that is highly specialized in the art of money making, through debauchery. It is where you can find Luna, Amber, and Ki-ki.

It is unlocked after completing a transport mission for Soran with Kivir. After that you can access it by clicking on Kivir and selecting "Go into the Brothel".

Improving the Brothel
Improvements for the brothel can be made by speaking with Luna and completing quests for her

Revitalizer
Luna needs 3 Revitalizers to improve the drinks. We can get Janet to make this for us after progressing her questline to the point where she's willing to cook for us. Each Revitalizer requires Mana nectar x2 to make. Mana nectar needs to be grown and harvested from our Garden. It's seedling looks like a bulb, and when it matures it looks like a blue drooling flower.

Silk Cloth
To craft Silk Cloth, she gives us the crafting recipe Antique Rag x2 + Ectoplasm. We can acquire these materials from the minigame Karos' Defence. Then to craft it, we need to visit Lily to perform Alchemy.

Hiring Someone
When we complete both the Revitalizer quest and Silk Cloth quest, when can ask Luna to hire a new performer. She will hire the goblin Ki-ki.
