Crystal equipment

Crystal equipment is a recurring set of Heavy Armor that appears in several Final Fantasy games. They are often among the better sets of equipment available, although not the best. Shield, Helmet, Armor, and Gauntlets typically make up the set, although Crystal Swords also appear sometimes.

Final Fantasy
The Crystal equipment set of Shield, Armor, Helmet and Gloves are the strongest pieces of the equipment in the original release, although the Genji equipment is just as strong, if not stronger, in the Advance port.

Final Fantasy III
The Crystal equipment set of Shield, Helmet, Mail and Gloves are the second strongest in the game, surpassed only by the Onion Equipment and a handful of other equipment pieces. It can be bought at Forbidden Land Eureka.

Final Fantasy IV
The Crystal Shield, Helmet, Mail, and Gloves are found in the Lunar Subterrane and are Cecil Harvey's strongest equipment. The Crystal Ring can be won from Red Dragons and is usable by everyone. In the Advance release, a handful of stronger equipment pieces are found. Cecil's strongest weapon in the original release, the Ragnarok, was originally translated as "Crystal".

Final Fantasy V
The Crystal Mail and Helmet can be bought in the Phantom Village, but the Crystal Shield must be Stolen from Crystelle. The Helmet can also be won from Crystelle, and the Mail won from Crystal Dragons or Sekhmet. Their defensive abilities are surpassed only by the Genji equipment.

Final Fantasy VI
The Crystal Armor, Shield and Helmet are available for sale in Maranda in the World of Ruin and are the best heavy armor available for sale, although many rarer, stronger pieces of armor can be found and won. The Crystal Sword, the second strongest buyable sword, is also for sale in Jidoor, and is Leo Cristophe's weapon of choice. The original Eight Dragons can also be Metamorphosed into the various equipment pieces.

Final Fantasy VII
The Crystal Bangle can be bought in Mideel, and is the strongest armor that can be bought, although many stronger pieces of equipment can be acquired elsewhere. It provides six Materia slots in three linked pairs. Various Crystal weapons, including Cloud Strife's Crystal Sword, can also be bought in Mideel.

Final Fantasy X-2
The Crystal brand of accessories are usually the strongest type of stat-raising accessories. Crystal Bangles raise HP by 100%, a Crystal Ball will raise a character's Magic stat by 50, and the Crystal Gloves raise Defense by 60.

Final Fantasy XII
The Crystal Shield can be bought in Archades and Balfonheim and is one of the stronger shields available, but not the strongest.

Final Fantasy Tactics
The Crystal Shield, Armor, and Helmet are the most expensive and powerful heavy armor that can be bought at a common outfitter.

Dissidia Final Fantasy
The Crystal Set gives a bonus of 20% to EX Force and EX Core absorbtion. In order for this bonus to be aquired, the character must equip three pieces of Crystal Equipment.
