Skull Cavern Elevator is an awesome mod that will add an elevator to the game. You can use this in a normal way, to get to the different floors of the mine, but it will also be added to the Skull Cavern. This means that you will be able to take a trip to the different floors of the mine, just like in a normal mine.

The elevator is updated every 5th floor by default.

This mod will give you an easier time when playing the game.
