How do I unlock the "The Hero's Cache" side quest in The Legend of Zelda: Breath of the Wild?

To unlock "The Hero's Cache" side quest in The Legend of Zelda: Breath of the Wild, you need to follow a specific sequence of events and interact with the right NPCs. This quest is part of the DLC expansion pack, "The Master Trials," so you must have purchased and installed the DLC to access it. The quest revolves around finding a hidden treasure chest left by a legendary hero, and it requires you to solve a riddle to locate the chest. HereÔÇÖs a detailed guide on how to unlock and complete the quest.

First, you need to ensure that you have the DLC installed. Once you have the DLC, the quest will automatically become available after you complete the "EX Treasure: Ancient Mask" quest, which is also part of the DLC. To start "The Hero's Cache," you need to find the quest giver, Kass, who is located in the Hyrule Ridge region. Kass is a Rito bard who often gives you shrine quests and other challenges. He can be found near the Tabantha Tower, specifically at the coordinates (-2850, 0480, 0220). When you approach him, he will sing a song that contains a riddle about the location of the treasure.

The riddle Kass sings goes like this: "A hero's cache, a treasure rare, lies hidden in the dragon's maw. Seek the place where the earth drinks the rain, and there you'll find the hero's awe." This riddle is the key to finding the treasure. The "dragon's maw" refers to a specific location in the game, which is the Thyphlo Ruins. The Thyphlo Ruins are located in the northern part of the map, near the Korok Forest. The ruins are shrouded in darkness, so you will need to bring a light source, such as a torch or a fire weapon, to navigate through the area.

Once you reach the Thyphlo Ruins, you need to find the "dragon's maw," which is a large stone structure that resembles a dragon's head. Inside the mouth of this structure, you will find the treasure chest. However, the area is filled with enemies, including Keese and Stal enemies, so you need to be prepared for combat. ItÔÇÖs a good idea to bring weapons with high durability and some healing items, such as hearty meals or elixirs, to ensure you can survive the encounter.

When you open the treasure chest, you will receive the Phantom Ganon Armor set, which includes the Phantom Ganon Skull, Phantom Ganon Armor, and Phantom Ganon Greaves. This armor set provides stealth and attack bonuses, making it a valuable addition to your inventory. The armor also has a unique appearance, resembling the dark armor worn by Phantom Ganon in previous Zelda games.

One important tip for this quest is to make sure you have enough stamina to climb and explore the Thyphlo Ruins. The area is quite large, and you may need to climb several structures to find the dragon's maw. If you donÔÇÖt have enough stamina, consider cooking meals that increase your stamina or using stamina-boosting elixirs. Additionally, the darkness in the Thyphlo Ruins can make it difficult to see, so having a light source is crucial. You can use a torch, a fire weapon, or even the Lightscale Trident, which emits light when wielded.

A common mistake players make is not bringing enough light sources or stamina-boosting items, which can make navigating the Thyphlo Ruins more challenging than it needs to be. Another mistake is not being prepared for the enemies in the area. The Keese and Stal enemies can be quite aggressive, so having strong weapons and armor is essential. If you find yourself struggling, consider upgrading your armor at a Great Fairy Fountain or cooking meals that provide defense boosts.

For advanced players, there are a few optimizations you can make to complete the quest more efficiently. One strategy is to use the Sheikah Sensor+ to locate the treasure chest once youÔÇÖre in the Thyphlo Ruins. This can save you time by guiding you directly to the chest. Another optimization is to use stealth to avoid unnecessary combat with the enemies in the area. Wearing stealth-enhancing armor, such as the Sheikah Set, can help you sneak past enemies and conserve your resources.

In terms of required items and preparation, you will need a light source, such as a torch or fire weapon, to navigate the Thyphlo Ruins. You should also bring weapons with high durability and some healing items to deal with the enemies in the area. If you have the Sheikah Sensor+, it can be helpful for locating the treasure chest. Additionally, having stamina-boosting meals or elixirs can make climbing and exploring the ruins easier.

An alternative approach to this quest is to use the Master Cycle Zero, if you have unlocked it, to quickly travel to the Thyphlo Ruins. The Master Cycle Zero can help you cover the distance more quickly and avoid some of the enemies along the way. However, you will still need to navigate the ruins on foot once you arrive, so the same preparation and strategies apply.

In summary, "The Hero's Cache" is a rewarding side quest that requires you to solve a riddle and explore the dark and dangerous Thyphlo Ruins. By following the steps outlined above, you can successfully unlock and complete the quest, obtaining the Phantom Ganon Armor set as your reward. Make sure to prepare adequately with light sources, weapons, and healing items, and consider using advanced techniques like the Sheikah Sensor+ or stealth to optimize your experience. With the right preparation and strategy, you can overcome the challenges of this quest and claim the legendary hero's treasure.
