Highcliff Castle Ruins: Locked room

[Lone_Deranger]

Hi,

I am stuck in the highcliff castle ruins. I decided to help Slaan and so we killed all the Zombies. However, the story cannot progress because I cannot open one last room in the dungeon. It must be the room with the Lizardfolk which we are trying to save. The door is locked and it says "no success possible" when I try to pick the lock.
I searched the dungeon serveral times with the "z" key pressed. I've found no key or other way to open the door.
How do I open the door?

Try having Neeshka pick it with a thieves kit. I believe the door has a higher DC than most. Just to confirm for you, there is no key to the door.

If I remember right (I'm only in Act II so I am not a whole lot further) it seemed like you were supposed to find other lizardfolk in the ruins or something along those lines. At some point Slaan ports you to talk to the chieftan so maybe just try talking with him and see what options are available.
