Hello everybody
I have a problem in the 3rd chapter right at the beginning, in the section The Vengeance (The War Lady)

- I talked to Maladie twice
- I talked to Ranley
- then I looked at Alexandar and took him the gem
- then I went to the right decorated door and held the rock stone to the door, but that was without success.

I know from Lets Plays that at the first dialog with the door the codeword strength appears, which one must choose to open the door.

Only with me this dialogue option does not appear.

What did I forget to do? I play on a PS 4

You need to get a book from a dead magister on the upper deck which has the password.
