I'm getting quite frustrated as I am trying to breed a metal dragon with Water and Light, but haven't got one! I've been trying for about a month and have got all the possible combinations, even the super rare ones (not to mention countless winter dragons!) But no 'rare' metal dragon!
Just wondering if there are any better pairings, obviously not with a metal dragon because I dont have one!
Any other combinations you try will add more outcomes to the mix. You can always try and find a combo that has a chance of hitting some other dragons you want as well. Anything with a white and blue combination, as well as any other element will breed one.
It really is the luck of the draw. I'm not sure it helps for real, but I tend to go to a different combo when I'm frustrated, and then come back to hope my luck is better.
Hope you get your Metal!!
