Yes, we know the ruby combo now, but not when she just came out. That is why I still have rust in the den. But now that I think of it rust has only 6 hrs breeding... Oh, In yesterday's frenzy I just don't know anymore! I forgot which combo I used that gave me rust . Ah, well it does not matter anymore. I am trying to get my hands on the ruby dragon! And as I only have one scorch and one chrome dragon and two breeding dens, I have one den free to get a sandstorm, rainbow or bluefire dragon to compleet my goals.
Thanks for the breeding tips! Air-iron combo gave me another iron, but I will keep on trying!
