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

To start "The Thunder Helm" side quest in The Legend of Zelda: Breath of the Wild, you need to visit Gerudo Town, which is located in the Gerudo Desert in the southwestern part of Hyrule. This quest becomes available after you have completed the main quest "Divine Beast Vah Naboris," which involves freeing the Divine Beast from Calamity Ganon's control. Once you have completed this main quest, you can speak to Riju, the leader of the Gerudo, to initiate the side quest.

The Thunder Helm is a unique piece of headgear that provides immunity to lightning strikes, making it extremely useful in areas where thunderstorms are common. Riju will tell you that she cannot simply give you the Thunder Helm, as it is a sacred treasure of the Gerudo people. However, she will allow you to borrow it if you complete a series of tasks to help the townspeople. These tasks are essentially smaller side quests that you must complete to prove your worthiness.

The first step is to speak to various NPCs in Gerudo Town to find out what they need. There are four specific quests you must complete: "The Mystery Polluter," "Medicinal Molduga," "The Search for Barta," and "The Eighth Heroine." Each of these quests has its own set of challenges and requirements, so you will need to be prepared for a variety of tasks.

For "The Mystery Polluter," you need to investigate the source of a foul smell in the town. This involves talking to several NPCs and eventually finding a hidden Yiga Clan member who is causing the problem. You will need to defeat this Yiga Clan member to complete the quest. Make sure you have a good weapon and some healing items, as the Yiga Clan members can be tough opponents.

"Medicinal Molduga" requires you to defeat a Molduga, a large sand-dwelling creature, and bring back its fin. Moldugas are found in the Gerudo Desert, and they can be quite challenging to defeat. One effective strategy is to use bombs to lure the Molduga out of the sand and then attack it while it is vulnerable. Make sure you have plenty of arrows and a strong weapon for this fight.

"The Search for Barta" involves finding a missing Gerudo woman named Barta. She can be found in the Kara Kara Bazaar, where she has been spending time with a man named Loverboy. You will need to convince her to return to Gerudo Town. This quest is relatively straightforward and does not require any combat, but you will need to have a conversation with Barta and Loverboy to complete it.

"The Eighth Heroine" is a more complex quest that involves finding a statue of an eighth heroine hidden in the Gerudo Highlands. You will need to solve a puzzle to locate the statue and then take a picture of it to show to Rotana, the NPC who gave you the quest. This quest requires some exploration and puzzle-solving skills, so make sure you have a good understanding of the game's mechanics.

Once you have completed all four of these quests, return to Riju, and she will allow you to borrow the Thunder Helm. This item is incredibly useful, especially in areas where lightning storms are frequent, as it will protect you from lightning strikes. Keep in mind that the Thunder Helm is a borrowed item, so you will need to return it to Riju if you want to complete the quest fully.

Some important tips and considerations for this quest include making sure you have a good supply of weapons, arrows, and healing items, as some of the tasks involve combat. Additionally, it is a good idea to have a decent understanding of the game's mechanics, such as how to use bombs effectively and how to solve environmental puzzles. Common mistakes to avoid include not being prepared for the Molduga fight and not having the necessary items to complete the quests, such as a camera for "The Eighth Heroine."

Advanced techniques and optimizations for this quest include using stealth to avoid unnecessary combat and using the environment to your advantage, such as using high ground to get a better view of the area. Required items and preparation include a good weapon, arrows, bombs, and healing items. Alternative approaches might include using different strategies to defeat the Molduga or finding different ways to solve the puzzles in "The Eighth Heroine" quest.

In summary, "The Thunder Helm" side quest in The Legend of Zelda: Breath of the Wild is a multi-step quest that requires you to complete several smaller tasks to prove your worthiness to borrow the Thunder Helm. By following the steps outlined above and being prepared for the challenges ahead, you can successfully complete this quest and gain access to a powerful piece of equipment.
