The Cavern is a fifth level biome exclusive to the Rise of the Giant DLC. It is located beyond the Graveyard and served as a crystal mine for the King. It contains a variety of unique enemies in a series of carved tunnels, with a greenish visual atmosphere.

The layout of the Cavern is peculiar, as it contains narrow shafts, probably used by the miners to move around the area, as well as floating platforms and pools of lava. The Cavern is initially the only way to reach the Giant, who is located in the Guardian's Haven.

General information

Access and exit

The Cavern can be accessed from the Graveyard on all difficulties after defeating the Hand of the King at least once and having first accessed the area with the Cavern Key. Once the key has been used to open the biome, the Cavern remains permanently accessible from the Graveyard, and after the Giant has been defeated once, it can also be accessed from the Slumbering Sanctuary through a 2 BSC door.

The exits from the Cavern include Guardian's Haven and the Mausoleum.^FF

Level characteristics

Scrolls

The Cavern contains 6 scrolls, including 4 Scrolls of Power and 2 Dual Scrolls, which cannot spawn in areas requiring the Teleport, Ram or Spider runes. On (4+ BSC) there is a bonus Scroll of Power. When 3 Boss Stem Cells are active, this biome has 4 guaranteed Scroll Fragments, and when 4/5 Boss Stem Cells are active, this biome has 5 guaranteed Scroll Fragments.

Exclusive blueprints

• The blueprint for the Festive Outfit can be found by unlocking a door with the Garland Key, which is hidden throughout the level in a secret area on the roof. While it can be found on any difficulty, the door itself can only be accessed on Nightmare/Hell mode, as it is located behind a 4 BSC door.

• The blueprint for Flying Alcoholic Outfit can be looted from Skeletons.

Enemies

The Cavern is home to a few unique enemies, including Ground Shakers, Arbiters, Skeletons and Demons,^[a] in addition to more common ones. On higher difficulties, Lacerators are replaced by Failed Experiments.

In the table below, you will find which enemies are present in the Cavern depending on difficulty level. For each enemy, any common, uncommon, rare or legendary blueprints they carry are indicated. When applicable, the minimum difficulty level for blueprint acquisition is specified in brackets.

Lore

Alchemist grimoires

A research grimoire can be found next to barrels of crystals and a vat containing a body.^[1] The Alchemist was apparently trying to use the crystals as the ingredient for a cure for the Malaise:

• "We can do more with those crystals than sell them, I'm sure of that..."
• "Using them on corpses doesn't do anything for now, but I have to keep going!"
• "This Alchemist... Is he a madman or a genius?"

King statues

A statue of the King can be found in the Cavern, next to barrels of crystals.^[2] The Beheaded notes how inflated the King's ego appears, that he would go so far as to bring statues all the way to the Cavern:

• "Seriously? The King left one of his statues here?"
• "Is there no end to his ego?"

Miners

A lore room full of crystal barrels under the King's banner contains a letter left by a miner.^[3] It illustrates how isolated the miners were from the island's population, knowing little of the raging epidemic and the King's terrible measures to stop the spread of the Malaise. Despite being uninformed about the outsides of the Cavern, the miners hid weapons, presumably to defend themselves against the strange creatures within the caverns, and now the monsters from the Malaise:

• "A letter from a soldier."
• "There are two kinds of people in the world: those with loaded crossbows and those that dig."
• "... We dig."
• "We've dug for 7 months. 7 months here and still no news of the outside."
• "I hope everything is fine."

A storage room full of crystals and banners of the King contains a letter left by a watchman, which alludes to the Giant. The letter states that the Giant, who previously guarded the Castle gates, has been slain due to an unknown feud between the King and him:^[4]

• "The giant who was watching the castle gates is no more."
• "What happened between him and the King, I wonder?"
• "... I don't know what the Giant did, but judging by the spear, they must've had quite the... difference of opinion."

Trivia

• Assets for the Cavern were already present in the game files in early access, long before the biome was officially added.
• Occasionally, the Clock Tower can be visible far in the background of the level, beyond the Cavern itself.
• In a previous update, Cavern used to give the highest gear level in the game since its flawless door to Guardian's Haven would give XIII gear on 4+ BSC, 1 tier higher than its current gear level.
