As I was playing this afternoon, I got a reward that I never dreamed of. After winning the battle I received 1 X Elixir, 1 X Dry Either, 1 X Fuma Shruiken and The Best Ever 2 X Pink Tails. I know that this sounds totally impossible but it did happen. I tried to take a picture of the screen, but the batteries in my digital camera were dead.
I now have 4 Adamant Armor. I am trying to have 5 of them.
