Please see the Avatar of Destruction's page- it lists what elements it aligns with. You'll want to breed your current Avatar to dragons with those affinities (the categories are available on the wiki to browse through), bearing in mind of course that the resulting egg may be the parent Avatar (in your case Creation), the parent other dragon or an Avatar of Destruction (assuming you picked the correct element).
