Shimmer-scale Dragons are a special breed in three color variations (Gold, Silver and Bronze) obtainable through an event occurring during and/or after the Christmas holidays. Shortly after Shimmer-scales were distributed, they were considered extremely rare and one of the most valuable breeds on the site. However, with a radical increase in popularity, and thus breeding, they are becoming steadily more common. Currently, they are considered between rare and uncommon due to the lineage type and number being a major factor in deciding whether the dragon is highly valued or not (and as a result, the rarity of this dragon has become highly subjective).
