Unlike most of their dragon kin, luckdragons possess neither an immense physical strength, nor great magical talents, though they can still breathe fire, which is blue, as shown when Falkor fights Ygramul. Their only distinctive ability that sets them apart is their incredible luck in everything they do, as shown at one point in the novel when Falkor manages to locate and rescue his companion despite being lost in a violent, blinding storm and having absolutely no idea where to look for him. A luckdragon’s typical answer to how it is going to accomplish a nearly impossible feat is always “With luck!” Despite such carelessness, it seems their luck truly never fails and is a valuable asset for their companions. – via wikipedia
