My main team in battle order left to right.
Sha Ji - fully ascended + 11 emblems
Graymane -fully ascended lvl 11
Brienne - 2nd level ascended lvl 31
Renfeld - fully ascended lvl1
Jahangir - fully ascended lvl1
Exalted Monks lvl 4
Imperial Knights lvl 2
Rebel Sharpshooters lvl 4
Reanimated Knights lvl 3
Firecaller Wizards lvl 4
I do have a red 3* Trainer Hero to use on Jahangir when I get 9 more reds for maximum level upgrade.
Problem is the boss on this level can one hit kill any of my team and its mana recharge is pretty darn fast. So even when I do make it to the end with the full team and have enough potions to charge full HP and mana, leading off with Brienne followed by Jahangir (if he doesn’t get taken out right to start), I’m still toast 5 to 7 moves later.
Other heroes I have, Valen 2nd level ascended + lvl 7, Carver lvl 25, Gan Ju lvl 14, Azar lvl 10, Prisca lvl 5
Hawkmoon lvl 1, Bane lvl 1. The rest is a gaggle of assorted ‘feeder mice’ 1* with a Brogan and an Olaf awaiting their fate to be absorbed into other heroes.
I see some pretty high level players still using a well buffed Bane, or two, in their defense team.
