Cave 56

Resources

 * 2x Gold
 * 1x Monument Piece

Walkthrough
2 Dwarfs are required to beat this cave.

First, direct one dwarf to fall off the ledge to the right. Behind one of the pillars is a pressure plate. Have the dwarf stand on it. Now have your second dwarf exit through the entrance door into a hidden room with a lever and some gold. You can collect the gold and flip the lever, which should open a new door for your first dwarf.

Before moving your first dwarf, allow the second dwarf to exit the room. Now you can use your first dwarf to go through the new doorway and collect the other gold in this cave. To the right, there is a pressure plate. Stepping off of it will collect the monument piece.

After this, the entrance door becomes an exit, and both dwarfs should be able to reach it without issue.
