On the other side, take the lower path first and get one device from inside a chest held
by vines, and another from a spider's web. Return to where the path split and go up. Use
the torch to get the vines to let go of a swinging platform so you can cross the gap. Use
diffindo to make a fly, which will carry away the large spider on your left, leaving a web
for you to bounce on to reach the ledge to your left. There, you will find the third
device in a chest. Up the stairs, the bridge reaches solid ground. Dig up the last device
and go back to place it on the bridge.

Follow the path all the way up and back to find a student in peril held in a giant flower.
Use dark magic to destroy some rocks on the right on the path up and then use aguamenti to
make the flower bloom and release the student.
