Now I'm getting into Platinum eggs during the next breed event. Once I got to green, I started my path. I'll put it below, along with the progress I've made so far, and will update at the end of the next breed. (I might adjust this depending on how I want to go when the Obsidian dragons come out). For the dragons I've bred already in Gold, I've put ratings next to them per my other dragon reviews (1=breed and bench, 5=keep), and will be more detailed once I'm out of the gold tier.
Nassus + Naga => Nix, Danzig at cost of 25,600 tokens
Danzig + Nix => Ferrox (1), Basileus (1) at cost of 25,600 tokens
Ferrox + Basileus => Sekoronos (5), Khrysos (4), Bander (3.5) at cost of 100,000 tokens
Garzev + Danzig => Lumen (2) at cost of 25,600 tokens
Lumen + Skeoronos => Caladbolg, Mune, Cerbero at cost of 31,200 tokens
Cerbero + Mune => Kelvin, Kaiju, Kulan at cost of 64,000 tokens
Danzig + Ettin => Pandi at cost of 2,100 tokens
Pandi + Kelvin => Nosfer, Necura, Whalegnawer at cost of 39,000 tokens*
Necura + Sekoronos => Vulcan, Rizar at cost of 64,000 tokens
After those comes Sapphire tier, which I'll post once I get close to the last part of this path.
Thanks as always for reading!! Happy breeding Dragon Lords!!!
