I finally got into academy 2 and found the rope to go back to pipes level 1. After I left the room I could not get back in to get the kohar-root from the imp on pipes level 1. What am I doing wrong?
You can't find the way back? Normally , you go very near to the hole (dialogue option), then click on rope. Entry is => take corridor past the mage lab, heading north, then take east door to the marker room - then east and north.
