I haven't seen anyone mention it on here, so I guess I will:
After the release of Chapter Five, it looks like one of Gerson's attacks has changed slightly. I was replaying chapter 4 after the new chapter released, and I noticed that attack 13 seemed a bit harder (it's the one where he stretches out the battle box horizontally. I think some of the gaps are smaller).
For context, I play on the Switch (1). I'm unable to upload a video right now, but I'll try to get footage if there's interest.
Is someone able to verify this happens on other platforms? Do we know which update/patch made this change? I'm also curious if there's been any other changes to his attacks, or to those of other bosses.
