on my second Tablet (Samurai) i managed to get past the Beast in madness. (i was halting it a long time just before wrath of the beast (in german "Zorn der Bestie") as i did not see the "legendary soul"-reward, which was before the archievment rebuilt-patch. Then i did beat wrath and saw my legendary soul-reward popping up. Now with only 6 levels away it took me no time and (5 trooper pharaohs) to beat the beast there, too. Not everything at 3 skulls and even with reviving at the beast (wich lowered the 50 ironites to 40 ... didn't care) and got me:

the Assassin Corrupt rescuer. From a trooper i knew she seemed pretty powerful and her energy-reset on the enemy may come handy fighting bosses. I'm fine with her.
Next step: beating the 1000 secret locations (only 140 left) on this tab and 49 more 5* characters on my main-account.
