If someone has updated guides on the new system please let me know and I will update my suggestions accordingly.Some useful Breeding Resources for you:

EDIT: The following breeding suggestions pre-date the massive Fall 2020 overhaul of the Breeding system.That allows you to recall duplicates for orbs, which you use for empowerment, and empowered legendaries are end-game state. But the best thing about breeding is finding reliable, recursive legendary dragon breeds. Breeding is the fastest way to expand your gold producing inventory, so always make sure it is jamming away.u/fancy_tetrahedron maps out all of the habitat token upgrade costs here. You need many habitats to house those dragons, and you need to upgrade them intelligently (more below).Breeding gets you both collection variety and an easy outlet for dragons to level up and collect gold from. You need many dragons at decent enough levels to produce a good hourly gold total for its rarity level.Producing lots of gold basically means two things: The more gold you produce the further you can build both outward and forward. The more dragons you have, the more gold you produce.Plus many give you great secondary rewards like food, gems, Joker Orbs, trade essence, unique items and much more. Compete in as many events as you can! This is the best way to build up a library of dragons you actually want to fight with.At minimum they will cover something important about the game and will probably contain at least one fact you had no idea about. Use all of the links provided in the sub sticky panel, chances are the answer to your question can be found in one of them.I will do my best to speak to returning players as I can, but I didn't live that dynamic so I'm uncertain of all the unique challenges you may be facing. While I call this a 'Beginners' guide, the truth is I am including many of the tips and tricks I use now as a level 98 Masters 3 player. It also serves as my thank you to this sub, u/Azurebane, and u/Deetlist whose content and input finally tied it all together for me. I'm writing this guide with the hope that it helps you avoid similar frustration I experienced learning this game. Added a write-up on Dragon Rescue, added updated event info.

2: Big updates to reflect the 'Empowerment Reborn' update.Did some formatting and content work on the Events. 3: Added u/rangarooney584 s great Breeding Event Island guide.2: Added u/fancy_tetrahedron's awesome list of habitat upgrade costs.
