How do you order the house brew? I have no idea how to do it and I want to access the fight club
I have found if you go to the right and down after entering the lower ark thing, ther will be a bunch of homeless people(sad but atmospheric, sorry I can't spell well I hope I spelled it right) if you go the the left person at the table near the top and gibe him a big fish he might give you a prompt or he might give you nonsense like saying there is an egg shaped shower in the PVP area of the bathhouse(you probably already knew that like I did XD) so just sleep then give him another fish the next day, and he might give you the right prompt then you can choose the house brew option. Sorry if you already knew that but I hope this helped someone.
Ran this through google translate for those too lazy to
"Excuse me in Japanese
I need the flag first
Go to the front (south) of Don's house
It seems that you have to feed the NPCs in the upper left corner where there is a group of homeless people, listen to the story of Fight Club and set a flag.
In addition, I replied in English before
I'm Japanese ... lol"
Obvious errors due to google translate but im sure you can work it out. Unfortunately patch 23 broke it but it should be fixed in the next patch. Thanks to SAMUS for this, im just the dumbass who translated it lol
