Okay, so I'm in Durlags Tower and past the four warders.
I enter a room and collect Kiels helmet. I return to the surface to offload some junk (you know, gems and jewels and stuff). When I go back into Durlags and get to the room, the door is closed and I can't get in. No-one has an answer for me yet.
I can't pick locks, cast knock, etc. None of these normal methods work.
Some options to explore....
1. Have I missed something?
2. If I restart TotSC, can I export my entire party and import to a new game?
3. It has been suggested I use a "CLUA". Help me here people...I don't what that it is, where to get it or how to use it.
Thanks anyone and everyone who helps.

You'll have to use whatever means that took you into the room in the first place.
The statue, the dummy or whatever. Actually you can acces the door control pannel from the other side of the wall...if you have got that far.

Exactly. All it takes to open the doors is fiddling around with the controls. It's usually the dummies that people forget to use.

Anyway, CLUA console is the cheats console in all Infinity Engine games. It's basically a free run of the game engine so you can do just about everything to the game in it. Create items, spawn monsters, move party around...

Speaking of the CLUA interface, thank god it's included, i was in the Tower and killed the warder that had the rune stone to open the door but i killed him against the southern wall of a hallway and no matter how i searched with the mouse for that magic hand with ring i could not find his body so popped open the CLUA interface and gave it to myself. Fun way to make a super-char without using Gatekeeper...=)
