Open the book with B and turn to Skills: each skill shows its level beside its name and, under its bar, the next thing it opens, such as “At 2: stone spear”. Make a stone axe on your first night and Crafting reaches 2, which opens the stone spear the same night. Arrows wait for Crafting 6, the bow for Woodcraft 8, and cabin walls for Building 9, so a first hut is wattle or thatch.
Mining is a skill now: every blow into ore trains it, and working a seam out pays most. A wolf you cannot butcher yet shows a gray mark naming the Hunting level it needs. When a skill levels up you hear the book’s pencil scratch once, and the Skills page carries a fresh pencil note saying what you reached, which fades once you have read it.
Level gates belong to the world, and a new world keeps them on for everyone in it. A hen now gives a small bone, so gorge hooks and a fishing pole are possible on the first day, and anyone can take meat from a wolf, though its hide still needs Hunting 30. A world saved before this change opens with each skill at the level its experience is worth now.
