Stage 4
- Move through the portal into the darkness (Be sure to mark the portals you go through so you don't double it up).
- Kill the monster that is in the darkness.
- Once you kill it, collect the pass.
- Give the passes to the party leader, and click on Lime-Green Balloon.
- Head into the portal and move on to the next stage.
Note: You can only attack them when their eyes are open. The two bottom portals contain monsters weak to physical attacks, and the three top portals contain monsters weak to magical attacks. One portal will have two monsters lurking inside.
