Meteors: Meteors are stony or metallic masses that fly through space. When the meteor hit the ground (becomes a meteorite), you can pick it up and use it to do amazing things!

Meteors have mighty power. If this power is melded into items, it can upgrade them while retaining their integrity and quality. For example, level 60 super items may become level 70 super items. The higher the level, the more difficult the upgrading. Failed improvements won't reduce the items quality, but will drop its durability.

Dragon Balls: Dragon Balls are magical vessels of powerful essence. They can be used to make just about any improvement to your character. Likewise, you can up-level your items just like you do with meteors.

Obtaining Them: These items are dropped by monsters, but can also be bought from other players. Requirements: Upgrading costs meteors, meteor tears or dragon balls. There are five levels of quality: Normal, Refined, Unique, Elite, Super. Your items must not be damaged in any way when you upgrade them (they have to be at maximum durability)
