I 3*'d Demonic Beasts on my first try blind, but Last Battle fucked me hard. I was close on my second try, then waited a day for my charisma to recover, only for me to fail ~8 more times before I got it. So much can go wrong in that opening, and then one of the flies constantly leaks through. I suppose it's my fault for relying on Berna to dodge scythe blasts and using Nanaly to challenge Verdinate.

Once I finally put Charlotte in the right place at the right time, it seemed to go well.
