Is there a better way to find a unique strongbox?

OP, it is driving me nuts too. And the scammers trying to get you to give them $$ for no box. And, like you, sick of monstrous treasure.

And OMIGOD the people that play this game can't read. If I get one more person telling me to do that Obama map or Plaguemaw because those count I'm going to scream. HELLO. I've done Plaguemaw 6 times. I found Kaom box in normal.

People, it is simple to read the list of challenges and open that one and read the list of boxes. Please read before saying things.


Edited to add: OP keep it up. After I posted the above I ran my next last monstrous treasure on canyon and I got Deshrets Storm!

You can do it too! Best of luck.
