What gives? I've read the walk thru for this level, and I'm stumped...I entered the electrical fan room, turned the fan up, killed the air elementals, and then, nothing?!? No scepter of air, the doof to the east of the fan, which leads to the next area is still locked, and I can't turn the fan up to make the electrical discharges stop? Any help, I'd greatly appreciate.
Have you visited all four rooms inbetween the labs? You'll find some hints concerning what's to do with the individual labs.
One more hint - not all sceptres are necessarily dropped by the lab's inhabitants.
All I can say without getting realy mixed up and confused is that everytime you find something new, kill something new, or open a new door one of the above will become available elseware on the level.
