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

To complete "The Thunder Helm" side quest in The Legend of Zelda: Breath of the Wild, you must help the Gerudo people in Gerudo Town by completing several smaller quests. This quest is given by Riju, the leader of the Gerudo, after you have freed the Divine Beast Vah Naboris. The Thunder Helm is a powerful piece of armor that grants immunity to lightning, and Riju will lend it to you once you have proven yourself by assisting her people. Here is a detailed guide on how to complete this quest.

First, you need to speak with Riju in Gerudo Town. She will explain that the Thunder Helm is a sacred relic of the Gerudo, and she cannot simply give it to you. Instead, she asks you to help the townspeople with their problems. You must complete four specific side quests given by different NPCs in Gerudo Town. These quests are "The Mystery Polluter," "The Search for Barta," "Medicinal Molduga," and "The Eighth Heroine."

The first quest, "The Mystery Polluter," is given by Dalia, who can be found near the town's water reservoir. She is concerned about the water being polluted. To solve this, you need to find and stop the source of the pollution. Climb to the top of the town's walls and look for a woman named Calyban. She is throwing hydromelons into the water. Speak to her and convince her to stop. Return to Dalia to complete the quest.

The second quest, "The Search for Barta," is given by Malena, who is worried about her friend Barta. Barta has gone missing in the desert. You need to find her near the Kara Kara Bazaar. She is trapped in a sand pit. Use a sand seal to pull her out, and then return to Malena to complete the quest.

The third quest, "Medicinal Molduga," is given by Liana, who is looking for Molduga guts to make medicine for her sick daughter. Moldugas are large, sand-dwelling creatures found in the Gerudo Desert. To defeat a Molduga, you need to lure it out by making noise, such as throwing a bomb or running on the sand. Once it surfaces, attack it with strong weapons. After obtaining the Molduga guts, return to Liana to complete the quest.

The fourth quest, "The Eighth Heroine," is given by Bozai, who can be found running around Gerudo Town. He is obsessed with the legend of the Eighth Heroine, a statue located in the Gerudo Highlands. To complete this quest, you need to find the statue and take a picture of it. The statue is located in the northern part of the Gerudo Highlands. Use the Sheikah Sensor to locate it if you have registered it in your Hyrule Compendium. Once you have the picture, return to Bozai to complete the quest.

After completing all four quests, return to Riju. She will be impressed by your efforts and will lend you the Thunder Helm. This helm is incredibly useful, especially in areas with frequent lightning storms, as it provides complete immunity to lightning damage.

Some important tips and considerations include making sure you have enough weapons and arrows to defeat the Molduga, as it can be a tough fight. Additionally, having the Sheikah Sensor upgraded to detect treasure can help you find the Eighth Heroine statue more easily. It is also a good idea to stock up on healing items and elixirs before tackling these quests, as some of them involve combat and exploration in harsh environments.

Common mistakes to avoid include not speaking to all the necessary NPCs to trigger the quests, or missing the location of the Eighth Heroine statue. Make sure to follow the quest markers and dialogue carefully. Another mistake is not preparing adequately for the Molduga fight, which can lead to unnecessary deaths and resource loss.

Advanced techniques or optimizations include using stealth to avoid unnecessary fights while exploring the desert, and using the environment to your advantage during the Molduga fight. For example, you can use the high ground to avoid its attacks and strike from a safe distance.

Required items and preparation include strong weapons, arrows, and healing items. It is also helpful to have the Sheikah Sensor upgraded and the Hyrule Compendium filled with relevant entries.

Alternative approaches include using different strategies to defeat the Molduga, such as using remote bombs to lure it out and then attacking with melee weapons or arrows. You can also use the environment to your advantage by hiding behind rocks or using the high ground to avoid its attacks.

Specific examples and scenarios include the fight with the Molduga, where you can use the sand seals to move quickly and avoid its attacks. Another example is finding the Eighth Heroine statue, where you can use the Sheikah Sensor to locate it more easily if you have registered it in your Hyrule Compendium.

By following these steps and tips, you can successfully complete "The Thunder Helm" side quest and obtain this powerful piece of armor. This will not only help you in your journey but also deepen your connection with the Gerudo people and their culture.
