Find access to the Lost Woods on your map and activate accessible Sheikah Stones along the way. Without the right aid, the exits in the forest will always lead you back. So don’t just put together a random sequence of directions. Your first destination is Tingle’s quarters in the tree stump near the beginning of the forest area.
Wake up Tingle and find the right exit
Enter the tree stump and go to the statue next to the sleeping Tingle. Activate the music puzzle there. Now you have to make sure that the large stone makes its way over the notes with your entries in the right time. Follow the given rhythm and observe when the next step is triggered. After the successful passage, Tingle wakes up.
Speak to Tingle to receive Tingle’s Dowser, then equip it. At each forest screen, approach the possible exits and use it. Follow the direction where its signal becomes stronger and faster.
So at every new fork in the road, decide based on the signal instead of memorizing a supposedly generally valid directional sequence. The device will finally lead you to the Lost Swamp with Gohmaracas. Also, if you find Cadence’s cave in the region, talk to her before entering the labyrinth.
Carefully through the swamp
The greenish poisonous areas are not ordinary paths. Plan your steps to avoid them as much as possible, and clear plants out of the way early if their tendrils restrict your space to move. A shovel and some bombs are helpful for blocked paths. Check chests and keys in the generated sections before moving on to the next completed area.
The room layout may change after a new attempt. Therefore, orientate yourself on open doors, stairs, switches and the obstacles in your actual room. If you run out of equipment or face the boss with too little health, returning to the upper world is more worthwhile than a series of hopeless attempts. Locations and stones that have already been explored remain useful for your further preparation.
Gohmaracas: hit the eye, avoid the beam
Gohmaracas moves sideways at the top of the arena. You cause damage to the opened eye; after a hit it closes for a few hits. Therefore, do not blindly follow every movement of the body. Bring yourself to the forefront, use the open time window and prepare the next evasive step.
This is especially important with the eye beam, which shoots straight down through the arena. If you stay permanently directly under the eye, you will be in the right attacking position and in the most dangerous line. Dodge sideways as soon as the beam is imminent. You can attack the eye from a greater distance with a bow if you have already found one.
Gohmaracas also uses nets and eggs. Free yourself from a net by trying to move further and don’t let too many larvae run around in the arena at the same time. After the first life bar is depleted, a faster phase begins with additional projectiles. Keep your avoidance area clear and continue to attack only the open eye. After winning, pick up Maracas and Heart Container. You have now received one of the four instruments for Hyrule Castle.
