Equipment
Equipment comes in three major categories. A character can equip one weapon and three pieces of armor. The third type, items, can be used in the field for various effects.
Weapons
Humanoid classes (mages, skulls, gunners, etc.) can equip seven different kinds of weapons and each class has a mastery rating for every weapon (E,D,C,B,A,S). This reflects the speed at which the weapon skill grows and the maximum level for that character with that weapon. Monster classes can equip one of two kinds of weapons: one focused on intelligence and the other and attack.
Armor
Armor is the best way to gain defense for your characters in the game. Each type of armor does different things: Heavy armor reduces speed but offers the best protection in the game, Robes increase intelligence as well as protect, and Light armor merely protects.
Items
Items can be found throughout playing the game or by simply buying them from the shops. Items can be used to heal characters, regenerate their SP, remove status ailments, and various other things. Buying items costs HL, the netherworld's form of currency. Additionally, items can be obtained by increasing the battle bonus gauge by competing a geo combo.
Items can be enhanced through the Item World, which can be entered at Holt Village and a few other places. While in the Item World, mysterious gates can appear, sometimes leading to shops that sell you items you can't find elsewhere.
