Continue to farm Dragon so that you CAN focus on your CB team. :)
Looks like you've hit the Dragon section of the Tips for New Folks, so congrats!
Enter The Dragon
Start Dragon progression. Your goal is to reach Dragon 20, where 6 star gear starts dropping. Lifesteal, Speed and Accuracy sets will help you build teams for all areas of the game, and also will help you gear up other teams for other dungeons. Leave those other dungeons for later though, as they all will require more specialized teams.
All of the above will help you progress in Clan Boss....
But why is clan boss important?
CB is a chance at having the best rewards in the game, on a daily basis, for free. Your ultimate goal should be to reach highest clan boss difficulty, UltraNightmare, within a year. Nightmare top chest by the time you've been playing 4ish months. Each day CB will give you a chance to get, daily, Sacred, Void and Ancient shards, as well as Legendary, Epic, Rare books, ascension pots, and gems. Plus you can get the exclusive gear sets: Immortal and Cruel, and getting useful gear without energy to farm it is sneaky good for you.
Toragi is really going to be so good for you in CB too. I'd be ranking him up as fast as I could farm food for him. :)
