Rarity

Rarity is a property of items. It is represented in-game by the item's color theme. Under rare circumstances, an item's rarity can be changed by Valve.

Rarity is a purely cosmetic property, and has no effect on gameplay. Items can have both a Rarity and a Quality value.

Tiers
Items are currently classified under the following categories, ordered from most common to least common: Common, Uncommon, Rare, Mythical, Legendary, Ancient, Immortal and Arcana.


 * Lower rarity items drop more frequently than higher rarity items.
 * The Rarity of items that can drop is dependent on the player's Profile Level.


 * Immortal items are never dropped.
 * Deleting an item in the Armory has a small chance of giving you back an item of the next rarity rank. Note: This feature has been temporarily removed due to a possible exploit.
 * Example: Deleting a Common item may yield an Uncommon item in return.
