Force Gem

Force Gems are triangular-pyramid-shaped jewels that have appeared in several Zelda series. Their roles vary from restoring power to the Four Sword in Four Swords Adventures to restoring Spirit Tracks and portions of the Tower of Spirits in Spirit Tracks.

Four Swords Adventures
Force Gems first appeared in Four Swords Adventures. They appear throughout each level, found on enemies, under rocks, frozen in ice, and more. The Links need to collect 2000 of them to empower the Four Sword. Once empowered, it can break Vaati's Dark Barrier at the end of each level. They come like Rupees in the game, the size of them and color determines its value. (Such as, getting a small Red Force Gem is more valuable than a small Green Force Gem) Often in levels, there will be an area that allows an opportunity to get many at once, mostly, these are defeating many enemies without being hit. Doing this awards combo points, which will give more Force Gems from defeating the enemies or lose the accumulated points. Beware though, because Tingle is in the game. After Link finds him under a rock, he will come when a big Force Gem or many lie around. He attempts to steal one. Link can throw a rock or enemy at him, but for humor, other Links can be tossed as well.

Force Gem Thieves

Phantom Hourglass
Force Gems return in Phantom Hourglass. They are used in Temple of the Ocean King and are an integral part of multiplayer Battle Mode. In the temple, they are used to complete a Triforce symbol in the ground that will open a door. These are gold-colored and slow down Link while he is carrying one. Oshus at one point in the game explains that the Sand of Hours are made out of Force Gems from the Ocean King.

The Battle mode force gems vary in size. The colors are changed during gameplay but the value of points remain the same. The larger it is, the more it is worth and heavier to carry. The Golden colored Force Gems signify an unclaimed Force Gem. The player colors for the Battle Mode are red and blue. Each will have Safe Zones in respective colors. The safe zones serve to hide Link from the Phantoms and the colored safe zones will change a Force Gem to its color, which adds its value to that players score. The neutral safe zones will turn red or blue gems back to gold and subtract the values from the scores.

Spirit Tracks
Force Gems return in Spirit Tracks with a more integral role within the story and universe. Force Gems lie within the various temples across Hyrule with the role of powering the Tower of Spirits, and they also serve as the symbol of the Spirits of Good. After the Tower of Spirits is destroyed by Chancellor Cole, Link must travel to temples and unlock each of of their Force Gems to restore and repair the Tower. This also restores more Spirit Tracks in its respective realm, usually revealing tracks that act as a shortcut to the Tower of Spirits.

Spirit Tracks can also be restored when the citizens of Hyrule feel a great emotion of gratitude, usually when Link helps them out, creating other Force Gems as a result of the energy emitted by their spirits. These Force Gems are necessary to completely restore all of the realms' Spirit Tracks as well as to uncover all of the hidden stations, such as the Lost at Sea Station and Disorientation Station. Moreover, Force Gems are attached on top of certain Warp Gates. Link must hit the Force Gems with bombs from his cannon to activate the Warp Gate and allow him to easily transport between realms.

The Battle Mode for Spirit Tracks has Link collecting as many Force Gems within the time limit while also trying to dodge various traps and attacks from Phantoms and other players.

Trivia

 * At first glance, the Force Gems' appearance seem to be inspired by the gem-like multicolored Triforces from the Zelda cartoon series. However, the Triforces are tetrahedrons and Force Gems are six-sided.
 * In Spirit Tracks, Force Gems share similarities with The Adventure of Link's Crystals, in that they are not so much items Link acquires from completing dungeons, but rather items he restores to those dungeons in order to access the final area.
