Force Gem

Force Gems were collected items in The Legend of Zelda: Four Swords Adventures. They are the items that power the Four Sword to truly defeat evil. When the Links collectively acquired 2,000 force gems, their Four Swords would power up to an Ultimate Four Sword. Though this is done cooperatively, many players fight one another for them. The reason is that, at the end of each mission, there is a ranking session. During this the game tallies up the kills, deaths, and eventually, force gem gain. Force Gem gain is the number one source of points in rankings, and ultimely, who gets 1st place.
