Frozen Loot Chests in the New Ice Caves

With the introduction of the new Ice Caves biome, exploration in cold environments could feel even more immersive. I propose a new small mechanic: Frozen Chests.

Any loot chest that generates naturally inside the Ice Caves should appear covered in a layer of ice. Players wouldn't be able to open them immediately. To access the loot, they would first need to clear the ice by placing a heat source nearby (like a torch or campfire) or by breaking the outer ice layer using a pickaxe or an axe.

This small feature would add a lot of survival atmosphere, reward environmental awareness, and prevent players from just sprinting through the new underground biomes without interacting with the freezing environment
