The Iron Labyrnith is found in the Wilderness at co-ordinates 054/169. Wander through the lush plants to find the cracked marble walls that surround the entrance to this underground cavern.

Located somewhere within this maze is a hidden drop spot that will take you to the Treasure Room where you can use the Iron Keys that you collect to unlock the treasure boxes. You will NEVER find the hidden drop to the Treasure Room on the first level of the cave.

Unfortunately if you have not already found the Treasure Room then you won't have found very many Iron Keys. The REAL treasure is to exit the Treasure Room to the north to Gim-Yi's Den. This den is the home of the Giant Iron Tigers who frequently drop Iron Keys along with Tiger's Hearts. So collect the keys and gather all the treasure you desire!
