Hi yesterday i can past the number of the beast in madness in my first round, i do this with a tricky allie. My got a purple golden son and i level up till 4* lvl 80. Because i used one from my tropers and i found that he can hits like a truck, but i was ignoring their ability "inmortality". This ability for 5 energy give you two turns of resistence, with this you can never die in any stage at least you face someone with steal or a two blue angels, virtually you can pass any level with this dishonoruable strategy.
My team was carrige rider eddie 4*, pharaoh eddie 5* and wickerman eddie 3*
Purple golden son and allied soldier blue
I just spawn inmortality every two turns (one in first round for an blue angel) and face the beast with the same strategy, the beast can cancel the resistence but probably you will live to cast again, and when started their transformation i used carrige rides special to kill him, he dont become phase two and died with this result and in the first run i felt more difficult beat in hard. I share this with you if you can't get your legendary soul i hope this works for you as work for me.
Grettings to all, btw i go a 5* Child of dammed (red) i want a axis general, or a yellow child is ok.
