Yeah, so you're not prioritizing right then... within a few weeks, a month at most, you should've had your first 6* champ. Which, yes, requires a LOT of grinding campaign - it gets a bit easier once you have that first 6* and can easily run them with 3 food champions in brutal 12.3 or 6. Though with good gear, perhaps your starter could already do that even at 5* level 50. 

agreed always focus on your campaing farmer like kael or any of the starter champs unless your lucky enough to pull some god tier lego then build him but even then id be weary of doing that because you prob wouldnt have books to make the lego better, so back to staying on track the starter champs are your first 6 star 90% of the time they will carry you through early game then from there start working on your next 6 star

Took  me  about  5  days  and  largely  free  to  play.  Sometimes  was  annoying  waitibg  for  energy  or  gems  but  worked  out.  I  maxed  elhane  and  didnt  regret  it.  

Hi, thanks for the answers.

I need to focus more on the starter champ. I have too many at the same time. For 6 stars you need 5 times 5 star champs and also you have to level them up first. How do you do that in 5 days? 

Probably I have to destroy some in favor of 6 stars....

Here is my current lineup 

i

Do not invest in Warpriest. She is pretty bad. Go with Ninja as your first 60. Also definitely dont invest in Shaman and Jizoh.  But dont use them as food either. You can get a lmited use out of them in Faction wars.

Your best line up here is:

Ninja, Kael, Magnar, Warmaiden, High Khatun

Kael and Warmaiden are definitely worth using rare books on. And you can even use legendary books on Ninja.

I raised Kael in 5 days too. It is important to be active and to concentrate on 1 champ (starter). My Kael 4*/40 farmed food on 9-3 (normal). Being 5*/50 - on 12-3 (hard). 

I fed him Sniper and Crusaider, preserved Warpriest though (and also raised her to 5*/50 - still my best supporter after 3 weeks of F2P).

Hi 

yes i am now also actively farming on 12-3 heavy the new ram. 4x4* for 1 5 Star and everything 5 times in a row is already a task but just focused on that it works already. You just have to have patience.  RSL Helper Tool is in continuous use ^^ 

I can't give away War Priest (yet) because she is the most important healer at the moment. 

Biggest problem now is the limited energy :D

I had my first 6star Campaign farmer within 2 weeks ftp.

After 7 weeks I have 7 6stars. Another will be 6starred next week.

You need to focus on 1 at a time, with the starter coming first (unles you pull a better campaign farmer).
