Iron Dragons, needless to say, are as sturdy as steel throughout, rendering either physical or skill attacks seldom effective. However, clumsiness has always been the Iron Dragon's Achilles' heel.
Green Dragons have incredibly strong regenerative abilities and possess venomous attacks; while Blue Dragons inflict water-related damage, with some variant Blue Dragons having ice-based attacks.
Needless to say, Red Dragons are synonymous with fire and explosions, very much like Bajie.
Yellow Dragon, as the only Ground Dragon among the seven pureblood dragons, boasts an ability envied by all, called Dragon Breath Missiles.
This is less a Dragon Breath and more a spell. By condensing the powerful Dragon Breath, it forms into massive missiles, the size of a small cottage, which automatically tracks any Flying Dragons in any location. Once hit, not only will it inflict significant damage, but it will temporarily rob the Flying Dragons of their ability to fly.
