How do I upgrade the Ancient Shield in The Legend of Zelda: Breath of the Wild?

To upgrade the Ancient Shield in The Legend of Zelda: Breath of the Wild, you need to understand the mechanics of ancient technology and how it ties into the game's crafting and upgrade systems. The Ancient Shield is part of the Ancient Armor set, which is designed to enhance your combat effectiveness against Guardians and other enemies that use Sheikah technology. Upgrading this shield requires specific materials and access to the Akkala Ancient Tech Lab, where you can craft and enhance ancient gear.

First, you need to unlock the Akkala Ancient Tech Lab. This lab is located in the northeastern part of Hyrule, in the Akkala region. To activate the lab, you must complete a quest called "Robbie's Research." This quest involves lighting the furnace outside the lab using a blue flame, similar to the process at the Hateno Ancient Tech Lab. You will need to carry the blue flame from the ancient furnace near the lab's entrance, which is guarded by enemies. Make sure to bring a torch or a weapon that can carry the flame, and avoid rain, as it will extinguish the flame. Once the furnace is lit, the lab will become operational, and you can interact with Cherry, the robot assistant, to craft and upgrade ancient gear.

To upgrade the Ancient Shield, you need to gather specific materials. The primary material required is Ancient Cores, which are rare drops from Guardians. You can find Guardians in various locations, such as Hyrule Castle, the Central Hyrule region, and the Akkala Citadel Ruins. Defeating Guardian Stalkers, Skywatchers, or Turrets has a chance to drop Ancient Cores, though the drop rate is low. You can also find Ancient Cores in shrines, particularly in chests within major test of strength shrines. Additionally, you will need rupees to pay for the upgrades. The cost varies depending on the level of the upgrade, so make sure to save up enough rupees.

Once you have the required materials, speak to Cherry at the Akkala Ancient Tech Lab. Select the option to upgrade the Ancient Shield. The upgrade process will consume the Ancient Cores and rupees, but it will significantly enhance the shield's durability and defensive capabilities. The upgraded Ancient Shield will have increased resistance to Guardian beams, making it an excellent choice for battles against these formidable enemies.

A common mistake players make is not preparing adequately for Guardian encounters. Guardians are tough opponents, and without the right gear or strategy, you may struggle to defeat them. Before engaging Guardians, consider equipping the Ancient Armor set, which provides additional defense against Guardian attacks. You can also use weapons with high damage output, such as the Master Sword or Guardian weapons, to take down Guardians more efficiently. Additionally, learning to parry Guardian beams with a shield can save you from taking damage and conserve your resources.

Advanced techniques for farming Ancient Cores include using the Master Sword's beam attack to defeat Guardians from a distance. This method is particularly effective against Guardian Skywatchers, as it allows you to attack them without getting too close. Another strategy is to use stealth to sneak up on inactive Guardians and attack their weak points, such as their legs or eye, to deal massive damage quickly.

If you are struggling to find Ancient Cores, consider exploring shrines more thoroughly. Many shrines contain chests with Ancient Cores, and completing shrine challenges can be a reliable way to gather these materials. Additionally, you can trade in your excess Guardian parts, such as screws and gears, at the Akkala Ancient Tech Lab for Ancient Cores, though this option is expensive and should be used as a last resort.

In summary, upgrading the Ancient Shield requires access to the Akkala Ancient Tech Lab, Ancient Cores, and rupees. Prepare for Guardian encounters by equipping the right gear and learning effective combat techniques. Explore shrines and Guardian-heavy areas to gather the necessary materials, and consider using advanced strategies to optimize your resource collection. With a fully upgraded Ancient Shield, you will be well-equipped to face the challenges of Hyrule's most dangerous enemies.
