You need to talk to the guard near the entrance of the bathhouse first before going back to the prank area.
I don't know, I checked and it works.
On that site there's only old versions of JP and plugins, you can find the latest updates on patreon
Almost all of these quests are done with crafting items. If you're at the bottom level the crafter it's one of the guys at the checkpoint to the tower. The mats for crafting items are of course found by farming the tower
Pretty much everything is either crafted at the tower entrance crafter, or you can buy them from the various traders, crafting will take much longer to get them, as most require materials that are from floor 6 or higher in the tower, while buying them simply costs money, I think I posted on this post a list of the items and how to get them from the first six or so floors, and for the most part the easiest way is to work in the smith each day, then work in the tavern each day, if you are doing a pure/clean run go get cleansed by the old woman as and when required, then go run around the tower, and do whatever crafting you want to.
