I am new here, but I have read some of your discussions and I see that there is a glimmer of hope for me, for I cannot remember where I have seen information on this particular matter.
To rephrase: I would like to make a dragon that is an offspring of different coloured/typed dragons; say, one is chromatic and the other is metallic, or both are different chromatic kinds. I already know that I can apply a half-dragon template to a dragon. That is not what I am looking for. A few years ago I have seen some published (electronically or in paper, not sure) source that contained information that I require. It might have been an unofficial .pdf (open licensed d20), or some sort of compendium with creatures and templates, but I remember it specifically addressed the issue and it even had a "fancy" name for such creatures.
Can anyone, please, drop me a hint? Pretty please!
