I sort of expected this to be talked about already, but since the search function reveals nothing...

I'm having a problem completing the Rescue the Slaves Quest in the Gnoll Caves in SoU. I can rescue the big batch of humans just fine, but that idiot half orc doesn't seem to realize that he's standing in the high forest. Do I have to escort him to Hilltop or what?

Normally you just have to lead him to the entrance of the Gnoll Caves.

Which I did.

Nothing happened. I assume that he's probably supposed to start a dialogue or something?

That idiot half-orc is a different quest I believe. IIRC I got XP for escorting him to the entrance as well as XP for offering to escort the other group.

You can talk to his half-sister the smith to verify that you rescued him. All she did was acknowledge the fact for me though.

I got the experience for rescuing the big group.

What's happening for me, though is that if I take the half-orc to the entrance of the cave, then I do not get a dialogue from him saying that I rescued him. If I try to force talk him, I get that "Wait here or abandon him" dialogue. He refuses to acknowledge that I rescued him.

I'll take him back to the smith on my way out of J'Nah's place if that's what it takes, but I'd like to have all the xp I can get down there.

It seems like her level is bugged too. I found the note saying to follow the lights of the same color and I won't get hurt. I've (literally) tried every hallway and branch of every hallway and still get wasted. I'm going to be upset if it's something so easy as pull the lever and she appears.

You have to pull the lever which opens a door of a specific color. As you probably noticed when you reach a fork then runs of colores "smoke" appear and you can only walk on those embranchments which have the same color as the door you came through. This should only be one way. At the end of the way you will enter a room with an elemental related to the color of the path. After defeating him you'll be teleported back to the lever. Now repeat this for every color and the door will open. J'Nah is after the door (and a cutscene).

Thanks, I'll try that.
