I've never been able to disarm the *!&?! think, even with my own L10 rogue, maxed out Pick Locks, etc. Ice Storm didn't work either. :cartman: However, there's an easy way past: situate your characters just outside the area effect wait until just after the lightning effect hit C for combat run - you can run past the trap without triggering it. It's obvious, I know, but I haven't seen anyone else mention it. When I need to visit the nodes, I just send my rogue past the trap, all the way to a node entrance. Party arrives with him, of course.
