In the game there are a few items that you should definitely have in your inventory. The absolutely basic ones include:
- Woodcutter Axe - you can use it, e.g. to cut down trees and acquire firewood, which is needed if you want to start any fires. You can find one of the first axes near the Old Man's camp, at the beginning of the game. Remember, that you can also use e.g. the bomb to bring down trees, and if absolutely necessary, also a melee weapon, but it is much better to save them for combat situations.
- Sledgehammer - it is mainly used to crush rocks and gain minerals that way. Hammers are quite common, you can find them in some of the shrines, houses in the village, etc.
- Korok Leaf - The huge leaf is mostly used for sailing, as you can use it to navigate a raft. You can usually find one near an abandoned boar, but most often you will simply get them after you cut down a tree. Whenever you bring down a tree, apart from the wood, you will also get a Korok Leaf.
Keep in mind, that these items will gradually deteriorate while they are used, so it is necessary to continually acquire new equipment. Check the condition of your gear on a regular basis, and dispose of the items which have low durability.
