To successfully open the Master Sword pedestal in The Legend of Zelda: A Link Between Worlds, you need to follow a series of important steps that reflect the classic Zelda gameplay mechanics. Here’s a detailed breakdown of the process:

Step 1: Collect the Pendants of Virtue
First, you must acquire all three Pendants of Virtue. These pendants are essential to prove your worthiness to wield the Master Sword. Each pendant is found in a different dungeon, where you’ll need to overcome various challenges and bosses to retrieve them.

Step 2: Enter the Lost Woods
Once you have all three pendants, your next destination is the Lost Woods. There are two known entrances to the Lost Woods:
– North of Kakariko Village
– To the left of Rosso’s house

Step 3: Solve the Lost Woods Puzzle
The Lost Woods contain a unique puzzle involving Poes that will attempt to mislead you. You must navigate through three successive areas, carefully avoiding the false trails that the Poes create. The correct route is often trial and error, with environmental cues to identify the right path.

– Pay close attention to the orientation of the Poes and any significant landmarks, as they can provide hints to guide you through the maze-like woods.

Step 4: Reach the Master Sword Pedestal
After successfully navigating the puzzle and avoiding the misleading paths, you’ll emerge in a clearing, which is the location of the Master Sword pedestal. Approach this pedestal, and you will be able to draw the Master Sword.

Step 5: Additional Upgrades
After obtaining the Master Sword, you have the opportunity to enhance its power later in the game. This can be done by collecting Master Ore and taking it to blacksmiths found throughout the game world.

Summary
In summary, to open the Master Sword pedestal:
1. Collect all three Pendants of Virtue.
2. Navigate to the Lost Woods through one of the entrances.
3. Solve the puzzle by avoiding the misleading routes created by the Poes.
4. Reach the meadow and approach the pedestal to claim the Master Sword.

Following these steps will not only allow you to wield one of the most iconic weapons in the Zelda series but will also advance you further in your adventure.
