Couldn't find a thread for this yet(maybe it's the late hour that I missed it...), please post the status of the Enemy on the block, the clearance of which would open 3 squares for monstalogists. This is the square west of this location:

...or alternatively south from here:

At present: An army of 66666 monsters is awaiting you towards west.
