The Frostblade is an item from The Legend of Zelda: Breath of the Wild. It is an elemental sword filled with ice power causing frost damage to enemies. Link can also use it to prepare food by freezing ingredients and lower the air temperature to survive moderate heat. As with the other elemental weapons in Breath of the Wild it's high durability and magical effects make it a good backup to the Master Sword during it's recharge period.
