On Campaign Battles throught all of them throuhg Nightmare. Nightmare some still two star. Cannot get two champions through alone. Last Nightmare stage lose most battles on boss but every now and then I get a win. Lyssandra and Scyl and Kael and Ninja but Ninja only gets me to last stage and he quickly dies.
So I need to point you up in the thread where Quinn dropped those two videos, and suggested taking Ninja up to 60. You 100% have the champions necessary to make this a really good account and you do not need to buy chickens. You need to be in Brutal 12-3, making food. You do not need to be in Nightmare campaign, at all.
