I want to breed a Peridot dragon, and crystal and cactus doesn't work for me after about twenty tries, give or take a few. So I'm going to go for the fog and iron combination. Anyone know how to breed a Fog dragon?
Straight from Fog Dragon Wiki:
The Fog Dragon can be bred by using any two dragons, in either order, containing the Water and Air elements at the Breeding Cave/Epic Breeding Island.
I've found that if you want a certain element to be dominate then make sure that dragon is levels above the other one.
