Upgrading Equipment

While armors color can be changed, there is normally only one type of armor that can be worn for each class and level. After first or second rebirth, level 70 characters can also use any equipment that is level 70 or below, regardless of character-class requirements.
Equipment has a range of quality levels - from lowest to highest, they are Normal, Refined, Unique, Elite, and Super. Equipment may be upgraded using either DragonBalls to increase the item's quality, or Meteors to increase the item's required level [which also makes the item stronger]. When upgrading an item via the DragonBall method, it becomes harder to accomplish the further up in the scale the item is.
'Fixed' items have the most powerful properties of any type of item[16] but are limited to level 50 or lower, and cannot be upgraded in any way. These items cannot be created; they are only found when dropped by aide or messenger type monsters.
An item may also be composed, adding "+#" to the item's name, where # is a number between 1 and 9. Weapons, however, can be upgraded to +12. [17] This number, similar to the quality levels, gives the item extra stats, making it more powerful.[18]
Gems can be mined or dropped by slain monsters, and are used to add an effect to an item such as increased damage, weapon proficiency, or overall experience gain[19]. Gems are also needed for players to be reborn. To insert a gem into an item, it must have a socket; there are a maximum of two sockets per piece of equipment. Additionally, items can be blessed or enchanted, which decreases damage or increases a player's health. There are 8 gems: Dragon, Moon, Violet, Kylin, Fury, Tortoise, Phoenix, and Rainbow.[19]
An item my also be blessed with the help of Super Tortoise Gems, in order to award the character by subtracting battle damage when in combat. A blessed item may relieve up to 7 percent of damage taken.
Gems are required for enchantment.[20] The amount of health is randomly selected - the higher quality gem, the high chance of getting a high enchant. A player may obtain up to 255 additional health per item. Gems come in three qualities: normal, refined, and super. The effect of the gem depends on the quality, with normal being the lowest and super the highest. Usually, the higher the gem's quality, the more expensive it is.
