For the cold biome in Legend of Zelda: Tears of the Kingdom, the Frostbite armor set would be a suitable choice. It will give you attack enhancement and add an icy explosion to your combos. To find it, you need to embark on a small expedition through the snowy peaks of Hyrule. However, it's worth stocking up on food with frost-resistant properties. The Frostbite set will not protect you from the cold.
The set includes 3 items:
- Frostbite Headdress
- Frostbite Shirt
- Frostbite Trousers
How to obtain the Frostbite Headdress:
You can find this item by reaching the Kilsi Lake Cave (coordinates: -3925, 2793.0015). Use the Rospro Pass Skyview Tower or the Ijo-o Shrine located in the West Hebra Sky Archipelago to reach the cave entrance.
Once inside, defeat the Horblin. It is most effective to use ranged attacks and the "Recall" ability. Explore the right side of the cave's hall. Find an additional passage blocked by icicles.
Clear the way using Bomb Flowers and stone weapons. Enter the room, open the chest, and take the first part of the armor set.
How to obtain the Frostbite Shirt:
The next item can be found in the Brightcap Cave (coordinates: -2995, 1657, 0199). You can reach the cave by heading southeast from Rito Village. Move straight towards the Tabantha Mountains on the right side of the road, and you'll find the cave entrance near a couple conversing.
After some time, you will encounter a Horblin on your path. Act as you did in the previous cave. Inside the cave, everything is straightforward, and there are no alternative paths. The next cave inhabitant eager to attack you is a Like Like. You can ignore it and simply run past.
The last challenge on your way to the target will be thorny vines. Here, the player also has a choice: burn them or simply climb over.
How to obtain the Frostbite Trousers:
The final piece of the armor will await you in the Hebra Headspring Cave (coordinates: -2897, 2511, 0393). It is located north of the location with the same name, east of the Rospro Pass Skyview Tower.
You will have to fight two Ice Keese there. Use any combat technique; there's nothing supernatural here. The main problem lies in the following: you need to cross the room while avoiding water, as it will damage the main character. Be cautious with that.
After completing the obstacle course, you need to leap to the other side. Then create an ice platform. To do this, you can throw an ice fruit or a white jelly chu into the water. Use the "Recall" ability to jump onto the platform. Then, reach the hole in the wall by using the wall. Inside, you will find a chest with the last item.
