Skull Cavern is located in the northwest area of the Desert. It is initially locked and requires the Skull Key to gain access. After entering the Cavern for the first time, a letter is received on the following day, from Mr. Qi. The letter begins the quest Qi's Challenge, which is completed by reaching floor 25 in Skull Cavern. Completing the quest awards 10,000g.
There is an infinite number of floors, or levels, in Skull Cavern. Similar to the Mines, the player advances through floors in Skull Cavern by finding a ladder on each floor, either by mining rocks or defeating enemies. The player can sometimes find a shaft, or hole, which makes it possible to skip 3-15 floors. Jumping down the shaft causes a small amount of damage. Unlike the Mines, there is no elevator to save progress, but on every floor there is a ladder at the starting point where you can leave the Skull Cavern. Each visit must start again from the first floor. If the player runs out of health or blacks out while exploring Skull Cavern, they will wake up sometime later on the same day, in Harvey's Clinic. A fee of 1,000g will be deducted for emergency surgery. Some items may also be lost.
Every ten floors the chance to find Iridium Ore increases significantly. The monsters in the Cavern also have a chance to drop ore and Iridium Bars. It can be a good idea to bring the Lava Katana or Galaxy Sword, as enemies are particularly strong. As with many other things, high Luck increases the frequency of ore veins, item drops, and the appearance of ladders/holes. Exploring the Cavern on a lucky day will increase the odds of finding loot and ladders. Since the frequency of Iridium Ore increases for every 10 floors descended into the Cavern, rapid descent is often more efficient for acquiring ore than thorough exploration. With a full bag of stone, its possible to descend to floor 300+.
The plaques that can be occasionally found on the walls contain enciphered messages.
