These items are used for support and in most cases provide additional stats to help players meet requirements or boost their abilities. While the first set of accessories do not have stats on them, they can provide defense, magic defense and other abilities. Always remember to check the stat requirements of accessories you have equipped to your character so that losing an accessory or other item that enhances your stats does not negate that accessory. If you have recently died and lost a piece of your equipment or changed a piece of equipment and your character is doing less or no damage at all or has weaker defense, make sure you are still stated correctly to use your equipped weapon and armor. Accessories have specific options per piece and additional options cannot be added besides the options specified for them. Each player can equip 1 Necklace, 2 Bracelets, 4 Rings, 2 Earrings, 6 Charms and eventually 1 Belt once they are released. Archers, in addition to this, can equip Quivers in their shield slot.
