Ok so this is my roster, I read some posts but since I do not have many champs I was thinking if you can tell me which ones are good for arena and which ones for the dungeons. 

I am close to building my fell hound as my farmer, what stats would you recommend as a minimum for him

Who should i 5* and who should i 6* , do if you could share which champs are good for which part of the game? my epics are Tallia, Stag Knight, Achak , Fellhound, Shaman, High Khatun, Boroth, Tainix, Pesti and Sandlash

I know deagon is where the good artifacts are, so pls help me make a team good for dragon 20 and also for spider
