I've defeated Queen Coraline, but it was insanely difficult because after waterlogging twice, her move can one-shot my party, unless they were guarding. My team was level 13 in case you were wondering. Was there anything else to do after the boss fight in this update?
The only bug I've saw was after Queen Coraline waterlogged twice, after she said something about her amulet being berried (even though I didn't), her visual art still remains on the right side of the screen during the fight. This only happened once.
Regardless, once again I'm happy that Polly now has art for all forms. I just wish to have the full resolution non-cropped artworks of Polly and her forms.
