Hi, I'm trying to rescue the Wizard in B9, but I think I'm stuck.
I followed the guide step by step. I completed all the required events before B9, including the B10 Wizard-related event. Arthur has already been captured and moved to B9-3, so I believe I've met the prerequisite.
According to the guide, before fighting the boss I should go back through the tunnel and head to the bottom-left area to trigger the Wizard rescue event.
However, when I go there, the door is still locked. The only message I get is:
"A faint light seeps out from beyond the door. All you can hear from inside is the continuous sound of something gurgling. You're curious about what's in there, but the door is locked, and it doesn't seem worth risking yourself over right now."
Is there another requirement that I'm missing? Or did I make a wrong choice earlier that prevents the Wizard rescue event from triggering?
Any help would be greatly appreciated. Thanks!
