You can't, but fog and lava or mud and blazing both work if you try enough.
To breed a iron dragon you use a metal dragon and earth dragon to breed your chances will be 100% chance at getting one.
its impossible to breed cool fire dragon with 100 percent chance
breed the volcano and medival to get armadillo
There is a way but not so 100 percent, breed cool fire and soccer you can get wind dragon because I breed the two dragons I got wind dragon
If you have a 'Pair' why not?
An F3 or an F4 cross kid
you breed bluefire right lvl 10 and crystal left lvl 10 worked for me
Earn 100 dollars and buy them.
100 hours
You can get seasonal dragon 100 percent real with lvl ten blazing dragon on left then lvl ten lichen it will work on first try it takes 48 hours to incubate and it doesn't need to be in epic breeding island it can be in regular breeding cave please add me i need gems or just add me for telling you
100+100+100=300. 300/3 is 100
the answer is unlikely to get a shiny you battle the Pokemon at least 100 times in a row
