Iced environment

The ice tunnel was bluish white, and as soon as he entered the hall, the marble itself radiated a bone-chilling coldness, a jet of steam expanding with each breath.

From the first torch, which was not manipulable, the temperature dropped a little more; this process increased every 5 torches.

25 degrees... 20 degrees... 5 degrees... -5 degrees... At this point, the cold was getting into his bones, but between the cloak, the armor, and all the objects he was carrying, he felt, to a certain extent, that he could endure. When the temperature reached -20, his teeth chattered, and moving forward was painful since the air that reached his lungs was too cold.

He didn't need to suffer much, so without thinking much, he took the lesser cold resistance potion, the cheapest one. The thermal sensation of comfort relaxed him. According to his calculations, the temperature continued to drop until it reached minus 50 degrees, it was like being at the North Pole taking a walk.
