Frosted Ice

Frosted ice is a translucent block created when a mob or entity wearing Frost Walker-enchanted boots moves over water. It cannot be obtained as an item and will quickly crack and melt if exposed to light or sunlight.

Frosted ice only exists as an item in Bedrock Edition, where it can be obtained using /give. Otherwise it can be placed with /setblock or /fill.

Frosted ice does not have a preferred tool, meaning it breaks at the same speed regardless of the tool used to mine it.[1] Breaking it with Silk Touch drops nothing, while breaking in any other manner produces water in the same way ice does.
