Treasure

Treasures are purchasable boxes that contain cosmetic items. They are obtained through the Dota 2 Store, charms, or the item drop system. Each treasure can be opened once to receive one or more random items from its listed contents.

Rarity

 * Each treasure comes with a drop list, categorized into rarity tiers.
 * Items in higher rarity tiers are unboxed less frequently.
 * An item's innate rarity does not affect drop chances.
 * quality couriers can be unboxed from some treasures at approximately 1-2% chance.
 * Chinese servers disclose an official drop rate of 6% for Rare items, and 2% for Very Rare items. These percentages may not apply to all treasures, or on non-Chinese servers.

Duplicates

 * Opening multiple copies of the same treasure guarantees a different item is unboxed every time.
 * Previously received items will not be unboxed again unless all items have been unboxed.
 * This rule does not apply to Rare, Very Rare or Extremely Rare drops.
 * After all standard items have been received, future treasure openings will yield random items from the droplist.

Trade Restrictions

 * Items unboxed from treasures cannot be traded or marketed for 1 week
 * However, restricted items can be gifted once to a friend.
 * This restriction does not apply to Extremely Rare drops.
