The 1.2 version of Genshin Impact is in full swing. Survival in the Dragonspine area is the most important, because the sub-zero temperature is a big challenge for players. The cold will play a key role called "sheer cold".
You need to use Warming Bottles to keep you warm so you can survive longer.
About Warming Bottles
Although the thermos is not the only way you can keep warm in the Dragonspine area, it is the most effective way. You can also use other ways to keep you warm all the time, such as eating Goulash food, it can reduce the freezing rate of your character's body temperature, but it cannot completely alleviate the cold. You will eventually need to walk to campfires and braziers to keep warm. In addition, you can also warm up at Statues of the Seven and teleport waypoints. But using Warming Bottles is a quick way to solve the problem, it can keep you warm all the time during adventure.
How to craft?
To craft Warming Bottles, you need to get the blueprints. In order to get a blueprint, you have to go to Frostbearing Tree. The tree has a leveling system, the highest level is 8 and the Warming Bottle recipe is at level 4. The way to upgrade the tree is to roam the overworld, open the chests, and find Crimson Agate. When you find Crimson Agate, take them to the Frostbearing Tree to upgrade it to level 4 and get the blueprint.
Once you obtained the blueprint, you can collect the ingredients for crafting the Warming Bottles: two Flaming Flower Stamen and two Starsilver pieces.
Flaming Flower Stamen
Cape Oath and Stormterror's Lair are both good places for farm Flaming Flower Stamen.
Starsilver
You can head to the north from Wyrmrest Valley, where there are many Starsilver pieces.
After obtaining these, you can go to the blacksmith for crafting. Because Warming Bottles are consumables, they will disappear after one use. If you want to start a long journey, you'd better bring a few more thermos.
When to use?
Another thing to note is that you'd better use them in blizzards, because it is difficult to keep warm there, and using Warming Bottles will give you continuous heat.
This is the way to craft Warming Bottles, which can help you resist the cold and make you survive longer in the Dragonspine area. You will continue your journey in the future.
