Abandoned Mine B4

"Rare and precious treasure is hidden in the abandoned mine. Can you find your way through the labyrinthine mine, avoiding the hidden monsters and dangerous traps to find the treasure?"

- Dungeon Background

To enter this dungeon, one player needs to have a Abandoned Mine Key (B4) to open the door at the start and open the chest at the end. Opening the door does not consume the key, so you only need one key to complete the dungeon, as it is consumed upon opening the chest at the very end.

Strategy

 * This dungeon requires 4 players to enter the dungeon. Once you are past the door, you should split into 2 groups, with one group going to the left, and the other going to the right. The right path is generally more difficult, so the more experienced players should take that route.
 * The left path is pretty simple. At a certain point the left path splits into two paths, and the two members there should split up and look for a lever to pull. After both levers have been pulled, the path to go down should be opened up, where you fight a boss. After defeating the boss, the floor should crumble, and you have the option to take a mine cart to go to the end. It's fine if you miss the mine cart, since you can walk to the end.
 * The right path also splits into two paths, and the player who is better at jumping should take the left path, since there is a difficult jump puzzle that must be completed. Halfway through the jump puzzle is a lever that must be pulled. After the lever is pulled, the player has the option to complete the jump puzzle, or they can go back up the ladder and take the right path to meet up with the other member. After both levers have been pulled, the path to go down should be opened up, where you fight a boss. After defeating the boss, the floor should crumble, and you have the option to take a mine cart to go to the end. It's fine if you miss the mine cart, since you can walk to the end.
 * After both sides have reached the end (after defeating their boss), the water should disappear and you will fight against a giant golden chest. Watch out for the coins, since they deal damage. After defeating the boss, the person with the key should open the chest to get the dungeon rewards.
 * If the right group is having too much trouble with the jump puzzle and the left group is already done and waiting, they can exit the dungeon and come back to assist.
