Good day all Raiders,

This is my first scroll and I am on a quest to gain more knowledge. I rely on your kind advice and expertise to help me in my quandary. 

Currently i am level 43 and have been playing for more than 40 days. I have three 6 star champions - Elhain (Farmer), Madame Serris and Apothecary who are pretty close to being maxed out (albeit with four star gear). 

My current roster for CB, dungeons is :

Elhain, Apoth, Madame Serris, Longbeard (Pulled him from an ancient) and Galek (My starter champ - level 50).

My Arena team is 

Apoth (Turn meter), Elhain (nuke), Madame Serris (Decrease DEF), Galek (Nuke). I am not able to gear Madame Serris effectively to go before Elhain since Elhain has my best gear and is maxed out in masteries. Still this is turning very effective as long as Galek does not fall in my opponents first wave.

So here is where I need your suggestions and desperate help - tell me whom do you think should I work on for 6 starring as my 4th and 5th 6 star. Also any suggestions on team compositions would be great!!!!

I know I have some good champs, but are they really suitable for my 4th and 5th - 6 Star champs? Currently I am working on Coldheart as my next level 50. My entire focus so far has been grinding the campaign Brutal 12-3 to 6 star my first 3. Hence haven't spent much time on grinding dungeons - only enough to ascend the champs whom i thought best - to 3 star ascension. 

I am providing screenshots of my rosters. 

Here is my Vault. My thought process - the warmaiden, Spirithost and Shaman are ones I do not want to sacrifice. I have copies of warmaiden and spirithost which I am reserving for the fusion of Relickeeper mission. I like Sinesha's skills but not sure where to use her at my current progress. The 5 champions in the vault who are level 40 starting with Skullsworn are just food to 6 star my 4th champion.

I like collecting good champs for the faction wars (I like the concept very much)

Also, i have spent around 100 USD on the game buying the 1 month pass and the 2140 diamond pack and other basic stuff i thought i got a good value for, before going F2P.

thanks all for your feedback!!!!
