Can't enter Mushin's Floor 9

[Glissando]

Recently started playing again after a year long hiatus and am unable to enter Jakdan's room on any of my characters despite beating Mushin's darkness dozens of times. Any help?

Pick up blue quest (non daily) and do F8 again.
I had same thing happen to me on my alt. Couldn't remember where it was exactly so I took all non daily that were available in the tower. Worked :D

I did every quest in Mushin's tower, still can't enter :(. Oh well.

No need to fight Mushin in the first place to go floor 9. Its always the one Kimki said, non-daily blue quest which ask you to defeat junghado. If you already did that, then I have no idea too. Maybe its a bug?

Yeah, I did that quest before F9 existed on all my characters, so it seems I won't be able to do Mushin's tower, thanks guys.
