Are we going to get stuck again?

If you have everything you need, Alexander will automatically say he's ready. If not, they give you a chance to go back and get whatever you want, but if you come back to the top of the mountain without all of the necessary items, you will still be thrown in immediately.

Ya, that's what I was saying.

[Enchantermon]

Okay. Then yes.

Must've been KQ2 I was talking about... 

1st playthrough I couldn't continue because of the collapsing bridge (crossed it needlessly several times at the start), 2nd time I killed the snake and gave away treasure to the mermaid. After finally consulting a guide I assumed the items and usage were essential for completion.

KQ6 - You can enter the castle without a way to "defeat" Shamir.
