You can obtain these monsters by leveling your legendary up to level 9 and then hibernate it on dream room
 You’ll get a random element, but you can change the element when the monsters have finished the hibernation process (it costs 5/25/ 125 diamonds; It’s random).
 Although they have fire, air, etc element, they only can live on special/any legacy habitat, so build a lot of special/legacy (elements don’t matter) habitat :D.
 You can breed Legacy + Legacy to get another legendary, so you don’t need to keep your legendary on legendary form.
 Haven’t got legendary ?? Visit this link and try the formula
 You can’t breed legacy/legendary monsters with other monsters beside legacy/legendary.
 Have other tips?? just leave them on the comment, and I will add them if it’s useful. :D. Thank you for other people who have contributed info below.
