Can't clear Tower of Otherworld Floor 50!

The 50th floor of the Otherworld Tower, what a splendid challenge! Urill, the boss, has a troublesome烈波 (烈波 -烈 wave), so bring those with 烈波 immunity or those strong against Ancient Species! Don't hesitate to use items like Snipers and seize a righteous victory, Gau!

What part have you cleared so far? It would be much easier if you had Doron's third form...

This is how I did it on my first clear! If you finish off Madam Devil with Manju and Ex while having full items, I think you can do it with Nyanpu on auto-pilot. Please switch to manual if you run out of money.

My current setup takes quite a bit of time.
