As the "Year of the Dragon" nears and end, are you hoping to find the fastest breeding combo to hatch a Panglong Dragon? You've had a whole year (but maybe you are new to the game). It's a cool dragon, and you should definitely try to snag one. Here are the details:
Breeding Pair: (Lava OR Obsidian) + (Rain OR Fog) OR Mud + Smoke
Breeding Time: 36 hours or 28 hours 48 min (with upgrade)
Availability: Chinese Year of the Dragon
Type: Fire, Air, Earth, Water
Price: 500 Gems (There are better things to spend them on...)
These dragons are among the best for the Earth Habitat (only surpassed by Paper) , making them great earners before you get better Epics. The 4 elements make them excellent for leveling your shrines as well, but the somewhat long breed time is a bit of a bummer.
