How do I start the "The Thunder Magnet" side quest in The Legend of Zelda: Breath of the Wild?

To start "The Thunder Magnet" side quest in The Legend of Zelda: Breath of the Wild, you need to travel to the Faron region, specifically to the Lakeside Stable. This stable is located southeast of the Great Plateau, near Lake Floria and the Floria River. The quest is given by an NPC named Kass, a Rito bard who is often found playing his accordion near stables or other notable locations. Kass is a recurring character in the game, and he provides many shrine quests and side quests through his songs and riddles.

When you arrive at Lakeside Stable, you will find Kass standing near the entrance, playing his accordion. Speak to him, and he will tell you about a shrine that is hidden nearby. He will sing a song that contains a riddle, which you must solve to reveal the shrine. The riddle goes like this: "When lightning strikes the dragon's mouth, the shrine will rise from the earth." This cryptic clue is the key to unlocking the shrine and completing the quest.

The shrine in question is the Shora Hah Shrine, which is hidden underground and can only be revealed by solving the riddle. The "dragon's mouth" refers to a specific location near the stable. To find it, head east from Lakeside Stable toward the Floria River. You will notice a large rock formation that resembles a dragon's head. This is the "dragon's mouth" mentioned in the riddle. The shrine is hidden beneath this rock formation, but it will only appear when the conditions of the riddle are met.

The riddle states that the shrine will rise when lightning strikes the dragon's mouth. This means you need to create a situation where lightning strikes the rock formation. To do this, you will need to wait for a thunderstorm. Thunderstorms are common in the Faron region, especially during rainy weather. If it is not raining when you arrive, you can wait at the stable or pass time at a campfire until a thunderstorm occurs.

Once a thunderstorm begins, you need to position yourself near the dragon's mouth rock formation. Equip a metal weapon or shield, as metal attracts lightning. Stand on the rock formation and wait for lightning to strike. When it does, the shrine will rise from the ground, and you can enter it to complete the quest. Be careful during this process, as standing in the open during a thunderstorm with metal equipment can be dangerous. If you are struck by lightning, you will take significant damage and may die if your health is low. To avoid this, you can unequip your metal gear just before the lightning strikes, but make sure to re-equip it quickly to ensure the lightning hits the rock formation.

An alternative approach is to use the Thunder Helm, if you have obtained it from the Yiga Clan Hideout. The Thunder Helm makes you immune to lightning, allowing you to safely stand on the rock formation during the storm. This eliminates the risk of being struck by lightning and makes the process much safer. However, obtaining the Thunder Helm requires completing the "Divine Beast Vah Naboris" questline, which is a significant undertaking.

Once the shrine has risen, you can enter it and complete the trial inside. The Shora Hah Shrine contains a puzzle that involves using electricity to power mechanisms and open doors. You will need to use metal weapons or objects to conduct electricity and solve the puzzle. The shrine rewards you with a Spirit Orb, which can be used to increase your health or stamina at a Goddess Statue.

In summary, to start and complete "The Thunder Magnet" side quest, you need to travel to Lakeside Stable, speak to Kass, and solve the riddle about the dragon's mouth. Wait for a thunderstorm, use metal equipment to attract lightning to the rock formation, and reveal the shrine. Be cautious of lightning strikes, and consider using the Thunder Helm for safety. Once the shrine is revealed, complete the trial inside to earn your reward. This quest is a great example of the game's environmental puzzles and requires careful observation and timing to succeed.
