beowuuf: If you mean using some lockpicks (which are referenced somewhere previous in this topic), then I think I have a problem

.
Having searched in all possible (and impossible) places to find such a tool (and having a headache bumping into all those walls

) I'm still stuck and desperate. I even tried to fetch some acid in a vial to melt that lock, but no luck.
To give you an idea of my progress yet:
I already found the bladed sun, the silver orb, the staff bearing the druid's mark and the platinum horn, every creature except the dragon and the banshee is dead.
EDIT: ok, after one more thorough exploration I found what I was looking for

. Thanks anyway.
