The Otherworldly Gauntlet

Managed to clear it on the first day somehow. The old man was so tanky I had to retry multiple times, and my party with Star Guidance was too laggy on mobile, so it wouldn't pass. I was worried if I could clear the Control Device without Wojanitsa, but it wasn't particularly difficult. For Blade Guardian, I used Bennett to clear the gimmick and brute-forced it. Night Song Bennett is the best.
