There is no practical limit to the number of floors (sometimes called levels) in the Skull Cavern.<ref name="integerlimit" /> Similar to [[the Mines]], the player advances through floors in the Skull Cavern by finding a ladder on each floor, either by mining rocks or defeating enemies.  

Unlike [[The Mines]], there is no elevator to save progress, but on every floor there is a ladder at the starting point where the player can leave the Skull Cavern. Each visit must start again from the first floor.

Unlike [[The Mines]], there is no elevator to save progress, but on every floor there is a ladder at the starting point where the player can leave the Skull Cavern. Each visit must start again from the first floor.

When ladders to the next floor appear, 20% of the time they will appear as a shaft (or hole) instead of a ladder. Shafts make it possible to travel 3-15 floors at a time. The number of floors dropped is based on an integer x between 3 and 8 inclusive, chosen with equal probability, with a 90% chance that the player drops x levels and a 10% chance that the player drops 2x-1 levels. The amount of levels dropped is predetermined based on the mine level, game day, and [[Random Seed]]. In particular, [[Luck]] does not affect the chances of jumping down a certain number of levels. This also means that if multiple shafts spawn on a given level, they will all drop the player the same number of levels, so it does not matter which one is chosen. Jumping down the shaft causes [[Health]] damage equal to 3x the number of levels skipped (although jumping down a shaft will never reduce health to less than 1). Note that if a shaft above floor 100 is calculated to drop the player past floor 100, it will be modified to only drop the player to floor 100.<ref name="shaftlevels"/>

If the player runs out of [[health]] while exploring Skull Cavern, they will wake up sometime later on the same day in [[Harvey's Clinic]]. A fee of {{price|1000}} will be deducted for emergency surgery. Several items may also be lost. Passing out at 2:00 am will cause the player to lose {{price|1000}} or 10% of funds, whichever is less.

The chance to find [[Iridium Ore]] increases slowly and steadily as the player descends into the Skull Cavern, rapidly increasing from level 10 to 100. See [[Skull Cavern/Ore Distribution]] for more details.

The monsters in the Cavern also have a chance to drop [[Iridium Ore|ore]] and [[Iridium Bar]]s, as well as [[The Mines#Special Items|special items]]. It can be a good idea to bring the [[Lava Katana]] or [[Galaxy Sword]], as enemies are particularly strong.

==Treasure Rooms==

Small rooms containing treasure chests, similar to those in [[The Mines]], can randomly appear at level 10+. [[Luck#Daily Luck|Daily luck]] and [[Luck#Luck Buffs|Luck Buffs]] affect the chance to find Treasure Rooms.

Small rooms containing treasure chests, similar to those in [[The Mines]], can randomly appear at floors 10+. [[Luck#Daily Luck|Daily luck]] and [[Luck#Luck Buffs|Luck Buffs]] affect the chance to find Treasure Rooms.

The probability of encountering one when entering a new floor equals to <code>0.01 + (Daily Luck / 10) + (Luck Buffs / 100)</code><ref name="dinofloor" />. This means Treasure Rooms have a base chance of 1% to appear with daily [[Luck]] increasing the chance by 1% at best or decreasing by 1% at worst, with the [[Special Charm]] adding 0.25%, and food buffs adding 1% for every point of Luck. In multiplayer, the luck values taken into account are the average of luck stats of players present in the Skull Cavern.
