They can be bred from 2 rare hybrids (Armadillo Dragon, Gummy Dragon, Soccer Dragon, Cool Fire Dragon are common choices)

It is a long shot so if you have 5 gems to spare, try breeding boost to increase odds.

Lastly, i found one in the daily deus vault so another legendary may be offered on another week and you could gamble for it for as few as 3 gems though your odds for it are also low.

Good luck with it.
