After the initial events in Lynna Village, Impa will lead you to her house. Inside, she will give you the Wooden Sword, your primary weapon for the early game. equip it to either the A or B button in your Subscreen. This sword is essential for defeating enemies and cutting down bushes that block your path. Without it, you won't be able to progress effectively.
The Wooden Sword is a basic but reliable weapon. Practice using it to defeat the Octoroks and Tektites you encounter on your way to the Maku Tree. It has a short range, so timing your attacks is key. cut down any bushes you see, as they often hide Rupees or recovery hearts. This early exploration and combat practice will serve you well in the dungeons ahead.
