However, you also start the game with five Mastered Items - items you will never have to build. They are completely indestructible.
These items are:
- Water Bucket, used for collecting Water from the River Stones,
- Basket, used for collecting Apples, Almonds, Blackberries, and Pears (and presumably Strawberries too)
- Burlap Sack, used for collecting Grass, and foodstuffs such as Corn, Lettuce, and Cucumber.
- Driftwood Palette, used for collecting Tin and Flint Shards.
- Wooden Knife, used for making items such as the Flute, the Basic Cage, and the Basic Net.
