Strike a target with ice
Ocarina of Time
The Ice Arrow is an optional item obtained late in the game in the Gerudo Training Ground. The Ice Arrows are not necessary for any dungeon, puzzle, or side quest. Their only purpose is to freeze enemies.
In addition to freezing enemies, Ice Arrows now make temporary ice platforms in water. When Link freezes a ChuChu, it turns into a climbable block that can also be pushed. That block melts after a while, becoming a ChuChu again. Both of these abilities are necessary for completing the game.
The Wind Waker
The Ice Arrows are given to Link, along with the Fire Arrows, by the Queen of Fairies at Mother and Child Isles. The primary purpose of the Ice Arrows is to gain access to Fire Mountain to obtain the Power Bracelets.
Breath of the Wild
Ice Arrows can be found in chests, bought in shops, and looted from enemies. Ice arrows can freeze most enemies and are strong against fire elemental enemies, such as Fire Wizzrobes. If an enemy is frozen with one of these, and Link hits the frozen enemy with a melee weapon, significantly more damage will be dealt.
