Nightmare campaign
Hi everyone, I'm currently stuck at 12-7 in nightmare campaign, last stage, and obviously I need to get 3 stars there to obtain the sacred shard, I've heard about a method using paragon and make him immortal, but I don't have this champion.
I refuse to believe that one is the only effective way to success there, but I tried many compositions with my current team and I just cannot.
Does anyone succeed in the last stage without using that paragon strategy?
I really appreciate some help here
Thanks
