There is no magic formula for a Crystal Dragon. I have three of them and each bred a different  way. I have to wait to find out what my 7th legend dragon is, but I used Pure Dark level 4 and Pure Electric level 4 this time.

You can check my blog for breeding charts. It has all successful legend dragon breeds in it.
