There are five levels of item rarity.

In order of increasing rarity, they are:
 * 1) white
 * 2) light blue
 * 3) purple
 * 4) gold
 * 5) green (only dropped by bosses in the Southern Shiverpeaks)

On weapons, Focus Items and shields the chance for a magical modifier or weapon upgrade increases with rarity.

On Salvage Items the chance for a minor, major or superior Rune increases with rarity.
