Force Gems first appeared in Four Swords Adventures. The Links need to collect 2000 of them to empower the Four Sword, which has lost its power because of Vaati's magic.[6] Once empowered, it can break Vaati's Dark Barrier at the end of each level.[7][8] Like Rupees in most games in the series, their size and color determine their value. Often, levels will have an area that gives an opportunity to get many Force Gems at once; usually, this involves defeating many enemies without being hit. Doing this awards combo points, which will give more Force Gems from defeating the enemies.[9] In some cases, the Force Gems are used as currency.[10] Sometimes, if big Force Gems are lying around, Tingle will appear and attempt to take them before Link can reach them; Link can throw things at him to deter him.
Force Gems appear throughout each level, found on enemies, under rocks, frozen in ice, and more.[11] Below is a list of the values for each variety of Force Gem:
Color alternating Force Gem: Its value depends on which color it is when obtained.
Force Soldier: A large green Force Gem with a sword and legs. If Link destroys it, it will become a big green Force Gem. However, if Link does not defeat it in time and it self destructs, its value will be reduced to one Force Gem.
Force Gem Thieves
Hinoxes will shake great amounts of Force Gems from Link while he is in their grasp.
Wizzrobes can continuously suck Force Gems from Link while dodging him at great ease and speed.
When Link takes significant damage, Force Gems will fall from him.
Phantom Hourglass
Force Gems in Phantom Hourglass are gold-colored. They are used in Temple of the Ocean King. In the temple, they are used to complete a Triforce symbol in the ground that will open a door. Just like a Boss Key, they slow down Link while he is carrying one and prevent him from attacking or defending himself.[12] At one point in the game, Oshus explains that the Sand of Hours are made of Force Gems from the Ocean King.[13]
In 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 Gold-colored Force Gems signify an unclaimed Force Gem. The Links' colors for the Battle Mode are red and blue. Each will have Safe Zones in their 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 Link's score. The neutral Safe Zones will turn red or blue gems back to gold and subtract the values from the scores.
Force Gems are found in floors three and twelve, both having three each. They're usually found on chests which can only be found and opened after solving puzzles, and it's not uncommon that other Gems are held by Phantoms as well, requiring Link to stun them first. In floor nine, the role of the Force Gems is taken by the geometrically-shaped crystals found in floors seven and eight.
In Spirit Tracks, Force Gems are integral to the plot. The Force Gems in the Forest, Snow, Ocean, Fire Temples emit energy that is carried by Spirit Tracks to the Tower of Spirits, which the Spirits of Good built to imprison Malladus.[14][15] When Cole and Byrne plot to resurrect Malladus, Link and Princess Zelda go to the four temples to restore the energy between them and the broken Tower of Spirits.[16] These Force Gems are colored according to the Realm in which they are in. They each emerge from the remains of a defeated bosses and rest on a winged pedestal that appears out of the floor. This restores the Spirit Tracks from the temple to the Spirit Tower, at the same time sending a burst of energy that restores another section of the tower.
The pedestal-mounted Force Gem is the symbol of the Spirits of Good which appears on the Rail Map and the Lokomo's vehicles. For the same reason, the Shield is studded with an ornamental Force Gem—the Lokomo Sword has one in its pommel. One of each pair of Spacetime Gates is adorned with a Force Gem whose color indicates whether or not the gate is active. The gate is activated by striking the Force Gem using the Cannon.
When Link helps certain characters, their happiness or gratitude causes them to emit Energy in the form of a small yellow Force Gem that restores yet more of the Spirit Tracks.[17]Anjean gives Link one that opens the Spirit Tracks in the Sand Realm.[5][18] The other 20 of these Force Gems restore tracks that are optional. These grant access to new shortcuts, Stations, Spacetime Gates and Rabbits (generally in the Realm the person is in). Link obtains the 20 Force Gems by transportingPassengers and Cargo from one location to another.
