Skull Cavern

Skull Cavern Entrance
A shaft for faster descending

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 Gold.png10,000g (Delivered by mail the following day).

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 Gold.png1,000g 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.

Bombs make quick work of densely-clustered stones and ore veins. They're also necessary for permanently defeating Mummies.

The Slingshot's Explosive Ammo is also effective in dealing with small groups of stones, Iridium Ore deposits, and incapacitated Mummies. Loading the Slingshot with Gold Ore deals substantial damage, making it potentially useful for dispatching tough targets. Explosive ammo can be crafted or bought at the Adventurer's Guild for Gold.png100g.

Exploit: In versions prior to 1.3, the player is immune to bomb damage while eating food. So, if a bomb is placed, then food is consumed at the right moment, the player would be able to stand within the bomb's radius without taking damage. This was patched out in version 1.3.


Staircases can be used for rapid descent or skipping troublesome floors. Since staircases do not stack, it can be more space-efficient to bring plenty of Stone and craft the staircases as needed.


Magnet Ring: The increased attraction radius of the Small Magnet Ring, Magnet Ring, or Iridium Band can be useful, especially when using explosives to mine clusters of stone or ore.

Burglar's Ring: The Burglar's Ring, acquired by fulfilling Gil's goal of slaying 500 Dust Sprites, can be valuable for getting larger amounts of useful drops from enemies. Serpents can drop Bombs and Spicy Eel while Purple Slimes can drop Iridium Ore.

Slime Charmer Ring: Use the Slime Charmer Ring, acquired by fulfilling Gil's goal of slaying 1000 Slimes, for bypassing the common slime enemies in the cavern and negating their slowing debuff.

Savage Ring: The Savage Ring provides a Speed boost on slaying a monster which can make up for time spent combating the cavern's denizens.

Warp Totems

A Warp Totem can be used to make a quick exit if supplies are running low or the day is almost over.
