Miniature

General
Miniatures, also referred to as "mini pets," are items that reserve one of your inventory spots. When activated, a small duplicate of the named creature will appear and follow you around. Miniatures were originally added by the developers to show appreciation for long-time players, but have since become available through a variety of different means.
 * You can trade, give away, drop, and destroy miniatures.
 * You cannot dye miniatures, or sell them to NPCs.
 * You can have multiple miniatures in your inventory.
 * Miniatures appear while you are in explorable areas, missions, towns, or outposts. There cannot be more than 20 miniatures per district.
 * To activate or deactivate a miniature, double-click on it in your inventory.
 * Only one miniature can be active per character at a time. If you activate a second one, it will replace the active one automatically.
 * Miniatures cannot attack, nor do they have skills or special abilities. They also cannot be targeted or cause collision. They do, however, count as an ally of the owner's party and can be affected by some AoE effects.
 * Miniatures take the form of creatures from any campaign. It is possible for someone who only owns a Prophecies account to receive a miniature of a Factions or Nightfall creature.

Birthday Present

 * Each character will receive a present when that character is 1 or 2 years old (Type /age in game to see a character's age). 1 year olds get a pet from the first series, 2 year olds get a pet from the second series.
 * If a character's inventory is full upon his/her birthday, the present will appear when next logged in with an empty space.
 * Double-click on the present to unwrap it and reveal the miniature.
 * You may keep the present forever; it will not vanish later.
 * You will not lose a miniature if you receive one via trading and your character is under a year old.
 * Each annual series has:
 * 8 White (Common)
 * 3 Purple (Uncommon)
 * 2 Gold (Rare)
 * 1 Green (Unique)
 * The first and second birthday presents can be distinguished by their descriptions. The 1st birthday present's description says "Happy 1st birthday!".

Collector's Edition Presents

 * Arena Net has prepared a miniature in appreciation for players who bought the Guild Wars Factions and Nightfall Collector's Editions.
 * Factions owners receive a miniature Kuunavang
 * Nightfall owners receive a miniature Varesh
 * Once you add the CD key to your account you will receive a message to type /special in any outpost or town. After doing so you will receive an item named Factions Collector's Edition Present or Nightfall Collector's Edition Present. Double-clicking on it will turn it into the corresponding miniature.
 * Each account may use this command to generate only one Collector's Edition Present.
