Got diamond dragon from breeding pure dark lvl 20 + terra lvl 11, lava dragon from breeding pure dark lvl 20 + fire lvl 10, great white dragon from breeding lvl 15 pure and lvl 7 ice dragon. From my tests and outcome it shows that only one of the parents need to meet the minimum lvl 20 requirement to breed these exclusive dragons, to be on the safe side if you are targetting to breed these exclusives, since we all know it sucks to wait for some crappy outcome on a failed breeding attempt. And I suspect it is easier using pure level dragons to breed exclusive (breedable ones) because normal hybrid + normal hybrid will always fail, at least for me.

Pure dark dragon can also act as Pure element, as I also got Pure Terra dragon from breeding lvl 20 pure dark + lvl 11 terra. Hope this helps.
