Skull Wall?(sea caves quest)

[Jackdaw Mask]

So apparently this is final day of quest(considering on previous day Katie said something about tides and tomorrow being final day of the break) and I broke the barricade but Katie tells me to go to "Skull Wall" but I have no clue what that is referring to. Like, Catacombs has lot of "Skull Walls" but is it any of those? Or should I reload to previous day because I already missed chance to do this one?

It's in the far southwest in the sea caves. You need some special skills to get there. From where you met Katie in the caves, go west. Then figure out how to get yourself across the numerous obstacles. Once through those puzzles, the skull wall and its door will be kind of southwest again.

If you mean the fish head with empty slot for skull and two gems, already been there but no Katie

[TechnoGoth]

In my playthrough she didn't appear there until I showed her the other half of the map, the necklace, and the skull and had acquired the key.

I guess I need to reload to earlier day to get necklace and key then because after I reloaded to day 26 destroyed barricade and returned next day everyone there including zombie pirates were gone and Katie still wasn't at the locked door

It's all on a day off from class. You need to have the skull, key, and your amulet to open the door. I know I missed it once, but that was a long game ago. You meet Katie first by the broken ship's hull and offer to help her with the treasure hunt. Then, either with the items you have acquired, or after you get the skull, key and Captain's hat, (or Katie gets the key and hat) she will show up at the door that needs the skull and amulets.

As I recall, it is possible for you to fail this quest, but when I did Katie had gotten the stuff she needed to open the door and I did not.

If the pirates are gone from the ship/card game area, then you probably are too late.

Okay, this time I managed to obtain both the key and skull and Katie showed up at the door. But still can't open it because I guess I still miss the other gem. So umm, is it possible to find it or is this one of those "You can't find it but Katie finds it on the final day" situations?

[Jackdaw Mask]

Okay, can confirm I still can't get past Death Door <_< So uh where the heck is the other gem? It doesn't seem to be anywhere in sea caves

(...Am I literally only one who can't find the gem? All other threads seems to have more difficulty with finding the pirates)

Nevermind, finally found the darn thing(I had checked sense magic on the skeleton but I had apparently forgotten to press search option)
