The Occult Cave is the main dungeon of Harvest Town which unlocks when reaching Manor Level 20. It's located on the right side of the Taoist Temple gate.
Killing monsters will give you Dark Essence which is a currency only used in the Occult Cave. You can also get the essence from using the pickaxe on corpses, the Snake Statue and opening chests.
The Dark Essence can be used to buy items or use the Spinning Wheel which is at every 10th floor (10-110). Some items you can buy with the Occult Cave currency allow you to increase your health permanently.
All monsters have to be killed before you can go to the next floor. Before every 10th floor (9-119) a boss will spawn and there is a chance that a second boss will spawn after defeating the first. All bosses have a chance to drop a weapon which can otherwise only be gained from Sam's Spinning Wheel.
Every 10th floor you have visited unlocks the Cave Elevator which allows you to go directly to that floor without having to go through all…
