How to Breed Monsters in Monster Legends

Get a Goldfield Monster by Breeding:

Gold Background: 2x Legend Combo
Silver Background: 1x Legend Combo

Dec 14: Important Update!

It appears that at least some, perhaps all, of the Legendary monster breeding combinations have been changed 2 days ago. So far the only reported combinations that are working are for:

Darkzgul, Thorder, Lord of the Atlantis, Goldfield, Nemestrinus, Rockantium, Vadamagma

New Breedable Epic Monsters!

Erpham, Drop Elemental, Tartarus, and Darknubis are all confirmed as breedable Epics now!

What is the Average Breeding Time?

The average breeding time is an estimate based on the odds and how long it takes to breed each of the possible monsters from a combination. This is just a rough estimate right now. Because of some shortcuts I took, it will always underestimate the amount of time.
