I said the words "Blessed Be Kerah" AND "Sanctus Kerah" but nothing happened. She just says "Only the worthy may enter". I can see on the map where the door should be because corridor and stairs show up but a wall remains in the way and no door is there?
What can I do now? Anybody else have this problem?

Try saying Holy Sanctus

Thanks but "Holy Kerah", "Holy Sanctus", every combo didn't work. Revert game didn't work either.

This is what it says on the walkthrough provided with the game. "Stand in front of the statue and say the words written on the amulet (“Santus Kerah” or “Blessed be Kerah”). The door into the true crypt will open." I think I typed in Blessed be Kerah. Are you sure you are spelling it right? You have to be in the "talk" menu and right in front of the statue. maybe that character has to be holding the amulet, I don't know. Anyhow it worked for me.
By the way I copied and pasted the words above so the spelling mistake of "Santus Kerah" isn't mine, don't know if this is significant or just a typo.

Do you have the amulet the words are written on?
