Can you breed sun dragons with others? Is it productive?
The Sun Dragon can only be bred with a Solstice Dragon, an Equinox Dragon or another Sun Dragon. The Solstice and Equinox Dragons were limited edition dragons and are no longer available for buying or breeding. Unless you already have either of those, you can only breed your Sun Dragon with another one, and I'm pretty sure a Sun Dragon will be the outcome.
I think you will get a sun from breeding those. Good luck!
