How do I access the shrine hidden in the Hyrule Castle area in The Legend of Zelda: Breath of the Wild?

To access the shrine hidden in the Hyrule Castle area in The Legend of Zelda: Breath of the Wild, you need to locate the Saas Ko'sah Shrine, which is situated within the castle itself. This shrine is unique because it is not visible on the surface and requires you to navigate through the castle's interior to find it. Here is a detailed guide to help you access this shrine, including mechanics, strategies, and tips.

First, you need to prepare for the journey into Hyrule Castle. This area is one of the most dangerous in the game, filled with powerful enemies, including Guardians, Lynels, and high-level Bokoblins. It is highly recommended to have strong weapons, armor, and plenty of healing items. Equip armor with high defense, such as the Soldier's Armor set or the Ancient Armor set, which also provides resistance against Guardian attacks. Bring weapons like the Master Sword, which deals extra damage to Guardians, or Ancient weapons if you have them. Stock up on hearty meals, elixirs, and fairies to ensure you can survive the encounters.

To enter Hyrule Castle, you can approach from multiple directions, but the safest route is from the north, near the Lanayru Wetlands. This path allows you to avoid many of the Guardians patrolling the area. Once inside the castle, you need to navigate through the interior to reach the shrine. The shrine is located in the library, which is in the eastern part of the castle. To get there, you can follow these steps.

Start by entering the castle through the main gate or one of the side entrances. If you enter through the main gate, you will encounter a large number of enemies, so be prepared for combat. Alternatively, you can use the waterways to sneak into the castle. There are several docks around the castle that allow you to enter through the basement. This method is less dangerous but requires you to swim or use Cryonis to create ice blocks to cross the water.

Once inside, make your way to the library. The library is located in the eastern part of the castle, and you can reach it by following the hallways and staircases. Be cautious of the enemies patrolling the area, and use stealth if necessary to avoid unnecessary fights. The library is a large room filled with bookshelves, and the shrine is hidden behind one of these shelves. To reveal the shrine, you need to move the bookshelf. This can be done by using Magnesis to pull it aside or by using a bomb to destroy it.

After revealing the shrine, interact with it to activate the Saas Ko'sah Shrine. This shrine is a Major Test of Strength, meaning you will face a powerful Guardian Scout IV. This enemy has high health and deals significant damage, so be prepared for a tough fight. Use your strongest weapons and shields, and try to perfect your parry timing to deflect its laser attacks. If you have Ancient weapons or armor, they will be particularly effective in this fight.

Once you defeat the Guardian Scout, you will receive a chest containing a strong weapon and a Spirit Orb. This shrine is one of the more challenging ones in the game due to its location and the strength of the enemy, but it is worth the effort for the rewards.

In summary, accessing the Saas Ko'sah Shrine in Hyrule Castle requires careful preparation and navigation. Equip strong weapons and armor, bring plenty of healing items, and use stealth or combat as needed to reach the library. Reveal the shrine by moving or destroying the bookshelf, and be ready for a tough fight against a Guardian Scout IV. With the right strategy and preparation, you can successfully complete this shrine and claim its rewards.
