Throughout the Kingdom of Hyrule, whether you're underground, on the surface level, or in the skies, chances are you have come across some pretty warm areas that you need protection in. These areas can have extremely high temperatures that cause Link to burn.
One amazing set of armor that can play off these hot temperatures is the Ember armor set. This set can be found in different caves surrounding Hyrule and can truly add some amazing features to your arsenal.
The Ember Set
The Ember Set is a perfect armor set to wear while you are in high-temperature regions of Hyrule, The Depths, or the Sky Islands. The set bonus will add flames to your attack when you are in these hot areas. The base defense of each piece is only 2. However, they can be upgraded at the Great Fairy Fountains throughout Hyrule.
You must have the Flamebreaker set to obtain the Ember Headdress and the Ember Shirt.
Ember Headdress Location
This piece of the set can be found in the YunoboCo HQ South Cave just north of Goron City.
Once inside the cave, you will need to defeat two Horriblins. Once they are taken care of, you will see a small opening on the other side of the cave that needs to be blown up or destroyed with weapons. Once you have gotten through that area, you will find a small room with all the required items to create a Zonai car.
Build the car by attaching the wheels and then use the steering wheel to move the car out of the room and into the cave's main room.
Inside the main room you were just in, use the Zonai car to travel across the lava. Once you reach the other side, you will find a chest.
This chest contains the Ember Headdress.
Ember Shirt Location
The Ember Shirt is located inside the Goronbi River Cave. This is just southwest of Goron City. You can reach it by taking the road out of the city.
Once inside, you'll have to defeat a Horriblin. Once that is taken care of, you need to use the platforms in the lava to get to the area where the platforms are falling from. Wait for a platform to fall and use Recall on it. This will allow you to travel to the area with the Fire Like and avoid the lava falling from the ceiling, blocking the way forward.
You'll need to kill the Fire-Like in order to safely continue through the cave. Once it is taken care of, travel to the ledge of the area to your right. There, you will see the lava flowing deeper into the cave, and you'll be on the other side of the lava that is blocking the path you were just on.
From here, shoot something that is made of water (Splash Fruit, Chuchu Jelly, etc.) at the lava. This will create a small platform for Link to jump on. You can continue on through the cave. The first place you can get off will have a chest with a resource inside. Then get back on the platform and ride until you're to the next spot you can hop off.
Once you reach the next area in the cave, jump off the platform. You will see a small opening up a slope. Enter into it to find your treasure.
This is the Ember Shirt.
Ember Trousers Location
The Ember Trousers are located inside Cephla Lake Cave. This is north of the Foothill Stable. Once there, you will see two brothers who have been exploring the cave. They hint that they need the nose of a dog. You can feed the dog some food, and he will take you to the exact spot where this can be found.
If you don't feed the dog, enter the cave to find that it is full of chests. This starts the quest "Misko's Cave of Chests."
This specific chest in the back left corner contains the treasure you're looking for.
The chest contains the Ember Trousers.
If you enter the cave wearing the Fierce Deity, set, a small passageway will open. This contains the Fierce Deity Sword.
