A title card reads "GopherCraft TerraFirmaCraft Season 1, Episode 6, Tanner" over the inside of Basket's house, which now has a red plank floor, glass windows, chests and a white wolf wandering around. The goal today is leather armor. "It's kind of a big, big process," Basket says, and admits to having "just sort of skimmed over the instructions."
Barrels by the pond
Basket crafts a barrel and a wooden bucket and heads down to the fresh water near the house. Flux mixed with a bucket of water gives limewater, and it takes trip after trip to fill the barrel. A second barrel gets plain water while Basket waits out the rain. To be safe, the first test is a single Small Raw Hide, sealed in the limewater. A third barrel gets water and an Ash Log to make tannin.
The missing step
The hide comes out as a Small Soaked Hide. Basket scrapes it with a knife on top of a barrel and gets a Small Scraped Hide, but the tannin barrel won't take it. After looking it up, Basket finds a third step: the scraped hide has to soak in water first. Once that's done, the line runs limewater, scrape, water, tannin. Basket labels the barrels with signs and keeps a chest beside them.
"Moment of truth," Basket says, opening the last barrel. "Yes, we have a leather."
Cap, tunic and a medium hide
The first piece is a Leather Cap, and its tooltip lists armor stats. Basket thinks about dyeing it black, tries a hammer on some lapis, and decides there must be a grinding wheel for that. A quiver is off the list for now, with no bow and no easy arrows. A medium hide gives just one leather. "That's stupid," Basket says, and the next leather goes into a Leather Tunic anyway. "I'm starting to look like I'm no longer a caveman."
More copper while it soaks
With the barrels working, Basket tries the prospector's pick near the house, finds a spot it says has a lot of copper, and digs a narrow shaft into stone streaked with red. The haul comes to about two and a quarter stacks.
Full leather
Back at the barrels in the rain, the large hide comes out as three leather. That covers pants, boots and a saddle, which Basket hopes to use on a horse someday. The episode ends inside the house with a third-person shot of Basket in a full set of brown leather armor, the wolf sitting nearby, before the end card.
