WOW Gold: Each set has a different ancient metal and unlocks different options
Ancient items: Even rarer than excellent items, these items have their defense/damage values increased beyond the levels of excellent items. Ancient items are characterized with text the same color as excellent WOW Gold items and a blue background behind the text.
A blue glow will appear around the outside of these items. Each set has a different ancient metal and unlocks different options.
The item carries the prefix of the appropriate ancient metal, for example, Apollo Pad Pants or Heras Skull Shield. Each set has a specific metal, and not all sets can have ancient metals.
Along with the same options as excellent items, ancient items can additionally have the following "set" options that are only applied when your character is wearing more than one ancient item of the same set.
The options are unique to each set. For example, a Gaion Storm Crow set has the following options:
Ignore enemy defense 5%
Double DMG rate 15%
Increase skill dmg +15
While an Argo Spirit Set has the following options:
Agility+30
Power+30
These are the second most expensive, rare and useful items on MU. There are 5 different jewels, each one with its own use. According to the story, each of the jewels is a fragment of the sealing stone that held Kundun before it shattered.
