Inscryption

The left side of the map in Act III brings in new game elements that broaden what you can do with your cards in a lot of fun ways. The bottom left area is related to Magnificus from Act II and involves adding the Mox gem mechanics to your Empty Vessels as well as cards in your main deck that can be fitted with Mox abilities 

It would seem that allowing for these new mechanics into the gameplay was a bit much for P03, because when you get to the boss of this area, you will find it isn't ready for battle and you must design the boss yourself. You get to pick its look and the game rules for the fight. Unfortunately, there is no easy choices to make the boss battle trivial, but there are a few choices that seem better then other:
 

 

If you're selection seems to give you an advatage, P03 may step in and make you choose a new rule before the round is over, so you may see some variance in the gameplay. Win the first round and you will add another rule using the above choices for the second half of the battle. Everything else plays out as normal and shouldn't be too difficult to complete. I found some of the rules made the game take a lot longer, but removed a lot of the challenge, as you can see in the linked video below:
