Frost Walker is a treasure boots enchantment in Minecraft that transforms water into temporary frosted ice beneath the player's feet and provides immunity to campfire and magma block damage. This unique mobility enchantment allows players to walk across water surfaces while offering protection from certain hazards.

Players can obtain Frost Walker only through treasure sources including jungle temple and stronghold chest loot, fishing for enchanted books, trading with librarian villagers of any level, or from raid drops in Bedrock Edition. As a treasure enchantment, it cannot be obtained through standard enchanting tables.

Frost Walker creates frosted ice in a radius of 2 plus the enchantment level around the player's feet when walking on ground level. The ice remains solid during continuous movement but gradually melts when the player stops, with nighttime providing longer ice duration. Additionally, the enchantment eliminates all damage from magma blocks and campfires without affecting boot durability.

The enchantment is mutually exclusive with Depth Strider, requiring players to choose between ice-walking capabilities and enhanced underwater movement. Frost Walker is ideal for players seeking creative transportation methods, avoiding water hazards, or exploring areas with dangerous heated blocks.
