Caves are large underground sections of the world filled with unique features. They are so large that they are generated as whole new maps upon entering. Caves have their own artwork, terrain, and maps. Various creatures, plants, and other objects that do not appear elsewhere reside within Caves.
SpelunkingA Cave can be found underneath a Plugged Sinkhole. Upon mining the plug, an open Sinkhole appears with a rope leading down into a new Cave. Each Cave is generated just like a new world. A different loading screen (pictured above) will play while it is created. While within a Cave, time in the world above continues to pass and vice versa. Once a Sinkhole is unplugged, Batilisks (see below) can emerge at Dusk and roam the surface world.
Each Cave begins in a small circle of light with a rope hanging down and a skeleton at the bottom. The world within a Caves are affected by a Day-Night Cycle, Cycle of the Moon, and the four Seasons. Caves are always dark depending on the locations. This means that Sanity slowly drains, and in areas of complete darkness, characters are vulnerable to Charlie. Some natural light does leak in from the surface at places, however, and there are other light sources as well. When the map is opened, players will see a new set of icons and terrain specific to the underground (pictured at right).
Giants and Hounds will not spawn in caves. If a player skips a hound wave while spelunking, the wave will occur as soon as the player emerges from the cave. If a player skips the spawning of a giant, that giant might also spawn upon resurfacing (sometimes skipping the warm-up "growling" period). Staying in a cave until the season changes will prevent the previous season's giant from attacking in this manner.
Depths Worm Attacks
In lieu of Hound and giant attacks. Depths Worms will attack the player at intervals similar to the Hound wave attacks on the surface, and will increase in intensity as the days spent in the world increase. Like Hound attacks in the surface, Depths Worms will automatically target the player unless distracted by another mob.
While underground, the player may experience Earthquakes. When this happens, the screen shakes and a rumbling sound plays. Rocks, Flint, Nitre, Marble, Gold Nuggets, and sometimes Red and Blue Gems will fall from the Cave ceiling. Each of these is preceded by a small shadow and causes damage if it hits the character. Many of the items that fall during an earthquake shatter when they hit the ground, but some will remain intact. Once the earthquake ends, Slurtles and Snurtles leave their homes and roam the Cave in search of minerals to eat.
- Cave Spider
- Bunnyman / Beardlord
- Rock Lobster
- Big Tentacle
- Depths Worm
More creatures can only be found in the Ruins, below the Caves.
Some surface plants are also found in caves, such as Saplings, Evergreens, Berry Bushes, Grass, and Mushrooms. Additionally, several plants only grow underground: Light Flower, Cave Banana Tree, Fern, and Mushtree and its Red and Green counterparts. Like the aboveground versions, Berry Bushes and Grass will regenerate after a few days.
Stalagmites are a common sight in any cave, and can be mined for Rocks, Gold, and Flint. Similar looking Spilagmites are home to Cave Spiders and Spitters, which can only be destroyed with a Pickaxe. Less common are the Slurtle Mounds, whichspawn slow-moving Slurtles and rarely, Snurtles. Additionally stalactites and various rock formations can be found in the dark areas of the caves.
Nightmare Fissures can be encountered in the caves, which look like jagged cracks in the ground, with a color that changes based on the Ruins' place in the Nightmare Cycle. Like the Plugged Sinkhole to the Ruins, 2-3 Nightmare Creatures which can detect and attack the player regardless of sanity level will spawn nearby. If the player has experience with combat, and prepares/chooses his ground carefully, these monsters can be farmed for Nightmare fuel, though the constant sanity drain in the caves should ensure hostile encounters with nightmare creatures anyway.
In Don't Starve Together, the Caves received some re-balances. As of now only dedicated servers may host Caves and Sinkholes, though players may create a Caves-only normal server. Their generation algorithm has changed to be more like the surface world, having less dead-end corridors. Gunpowder no longer starts earthquakes. Light Flowers now only light up when a player approaches them, and they now have a dormant state to prevent players from exploiting their limitless light.
Currently the Caves are in beta. As such, they are incredibly unstable and subject to change.
- Caves were added in the May 21st Underground update.
- The Caves used to have giant walls making it hard for the player to see. They were later removed.
- When Caves were first released and the player died in one, they would reappear at the Sinkhole at the surface taking no reviving items to get revived. The player could retrieve the lost items, but all the food would turn into rot.
- Caves will often generate long stretches of ground that end up leading to nowhere. These can become deadly traps if the player is pursued down one.
- Maxwell quotes that he plugged up the cave entrance a long time ago, and if the player mines it open, he will state that it was a bad idea. The reason for this may be all the hostile creatures down there.
- After sleeping in a cave, the morning tune and evening tune play at the same time.
- If the player starts a fire above the ground and then goes underground, no matter how much time is spent in the cave, the same fire will still be burning upon the player's return.
- If you get killed while going up/down a sinkhole, and you have a touch stone activated or a meat effigy at the surface, then your world will forever be stuck in the loading screen.
- If you plant seeds in a farm during Winter and then go down into a cave, the crops will grow.
