Recruit Tetsu
To recruit Tetsu get Alex (the item keeper) in your group and when he sells fried tacos buy 3. Next go to Lakewest and keep giving them to your hero. Once you done that steam should start coming out of your hero. Then go and talk to Tetsu and he will ask if you like baths and answer I love baths then he will say somethings and will build a sauna for you. The sauna is where you enter in the front not by the bar
