The most effective method for breeding your first panlong is Lava (lvl 10) + Fog (lvl 10). This has around a 17% success rate. It will take 36 hours to breed and another 36 hours to hatch. The egg will be red with blue Asian style writing.
A couple of other methods you could try:
The panlong dragon will only be available in 2012, the year of the dragon.
River &Iceberg Dragon
Mountain & Water Dragon
It's called a panlong dragon but anyway to get a panlong dragon you breed a mud dragon and a blazing dragon. but what is very strange about that combination is that you can get a rainbow dragon from that combination which is very nice but you will mostly get a panlong dragon.
love dragon and panlong dragon
mud then blazing maybe
It is the Chinese New Year dragon from the game dragonvale
Well the panlong dragon can be bred using a couple different methods. The panlong dragon's elements are as follows, Air, Earth, Water, and Fire. I used Mud+Blazing and for the first time I got a rainbow dragon and then a panlong dragon. Another possible combination is a Fog+Lava. Your welcome. =)
If it the dragons are level 10 you get a panlong dragon but if they are not level 10 you get a mud or a blazing or a lava but the panlong you must try it more times.
panlong+love
You don't breed a Kairos Dragon in DragonVale. You have to get parts to complete it.
you breed a ice dragon with a mine dragon
You have to breed a plant and a fire dragon.
As of July 2012, there has not been a star dragon in DragonVale.
You can't, but fog and lava or mud and blazing both work if you try enough.
