With my roster, what group will eventually make the best defense if they were fully ascended?
I don’t know much about grazul or Miki yet so currently I’d go something like
Rigard Richard Kash Colen Chao/Li
Or
Rigard Richard Boldy Caedmon Chao/Li
If others said Graz is a decent tank I’d think about
Merlin/Tibs Richard Graz Caedmon Chao/Li
What does your ascension mat inventory look like?
Right now I have the materials to ascend one 4* of each color past 3/60.
From left to right:
Scarlett, Tiburtus, Kashrek, Kiril, Li-Xiu. That’s my vote.
Perhaps Sonya instead of Kiril just to have a dispeller in the flank.
Defence is not the most important aspect of the game so I think you should concentrate on key all-around heroes. You should do rainbow leveling.
Blue feeders: to Grimm, then Kiril
Reds: to Boldtusk, then Colen
Greens: max out LJ, then work on Kashhrek, then Caedmon
Purples: to Merlin, then Rigard
Yellows: to Wu Kong, then Chao.
Merlin-Grimm-Kashhrek-Colen-Chao could be a decent defence team after you max these 11 heroes. But bear in mind that Merlin is not great on defence, he shines on offence.
