Temple of Ice

The Temple of Ice is, as its name would suggest an ice-themed location appearing in both Four Swords Adventures and Phantom Hourglass.

Four Swords Adventures
In Four Swords Adventures, the Ice Temple is the second stage in Frozen Hyrule. It consists of slippery floors and many pitfalls. The most commonly used item is the Fire Rod which can melt the blocks of ice scattered throughout many rooms. It has to be upgraded to Level 2 to create blocks that can be used to traverse the pitfalls near the end of the level. The only other obtainable item is the Boomerang. Bombs are available to solve puzzles near their cropping.

The boss of this stage is a pair of Ball & Chain Troopers. They are fairly easy, and their attacks are easily avoidable.

Phantom Hourglass
In Phantom Hourglass, the Temple of Ice is the location of the pure metal Azurine that Link must obtain in order to forge the Phantom Sword. It is found on the Isle of Frost, and is one of the final three dungeons in Phantom Hourglass. This dungeon provides Link with quite a few challenges, many of which force Link to employ every possible trick with the Grappling Hook, the item found in the dungeon. The dungeon's boss is Gleeok, a two-headed dragon that has also been seen in other Zelda games.

The surface of the Ice Temple, as the name may suggest, is a slick ice sheet surrounded by seemingly bottomless pits. The Grappling Hook helps Link speed through the hazards safely. The majority of puzzles here are levers to be pulled with the Grappling Hook.

The path to the Boss Key, as well as the room with the Grappling Hook are guarded by fearsome Yook.

It is optional whether the player completes this temple before or after the Goron Temple.

Trivia
The Temple of Ice in Four Swords Adventures is very similar to the Ice Palace in A Link to the Past.
