Every rock destroyed has a chance to spawn a ladder, becoming more likely as there are fewer rocks remaining. If this is successful, a ladder will spawn and prevent further ladders spawning from rocks. (In contrast, in the [[Skull Cavern]], there is a 20% chance that a shaft will spawn instead of a ladder, and this does not prevent further ladders/shafts spawning from rocks.)

(In contrast, in the [[Skull Cavern]], there is a 20% chance that a shaft will spawn instead of a ladder, and this does not prevent further ladders/shafts spawning from rocks.)

Specifically: Every rock destroyed has a base chance of 2% to spawn a ladder. This is adjusted by daily [[luck]], increasing by 2.5% at best (0.5% of which is added by the [[Special Charm]]) or decreasing by 2% at worst. It is also adjusted by luck [[buffs]] and the Statue of the Dwarf King buff that gives [[Statue Of The Dwarf King#Greater chance to find ladders and shafts|greater chance to find ladders and shafts]].<ref name="ladderchance" /> For example, food buffs add 1% for every point of luck. A hypothetical player with max daily luck and +1 luck buff would therefore have a 2 + 2.5 + 1 = 5.5% base chance to spawn a ladder for each rock destroyed. The inverse of the number of rocks remaining (after subtracting the rock that was just destroyed) is added on top of that (''e.g.,'' if 5 rocks remaining then 1/5 = 0.2 or 20%, if 100 rocks remaining then 1/100 = 0.01 or 1%). If no enemies remain then another 4% is added. Finally, after accounting for daily luck, luck buffs, and no enemies remaining, the Statue of the Dwarf King buff that gives greater chance to find ladders and shafts applies a 1.25 multiplier to the final odds.
