Don’t Starve Together: How To Find The Ruins

The Ruins are one of the most intriguing areas of Don’t Starve, but they are also hidden deep inside the caves and are particularly hard to find. This guide will tell you all about how to easily find the ruins, what you can do inside them, and also what to watch out for when you are there.


Beware that this guide is only for Don’t Starve Together, as different rules apply for the single-player version.

How to find the Ruins

The ruins are a biome inside the caves. They are not just any biome though, but a special one with specific rules and also unique loot. As such, they are designed in a way that makes them harder to find. In every Don’t Starve Together world you play, the ruins might be somewhere else, but the rules that apply to the biome are always the same.

Don't Starve Together Sinkhole Entrance

First of all: Find the Caves. The ruins are inside the caves, so you need to go down there. The entrance is called sinkhole. For reference, check the picture to see how the entrance looks like.

Once you are inside the cave, there are certain rules that apply to finding the ruins.

You need to find a specific biome that is commonly described as the “Lichen Area”. This biome is actually already part of the ruins but doesn’t look like it. It is huge and way easier to find than the actual ruins, but it will always lead into the ruins.

The Lichen Area has its name from the gigantic amount of Lichen that you can find inside (see the picture for reference).

How the Lichen Area looks on the map

The Lichen Area can be found by looking for big swamp areas with lots of lightbulbs. This area will always connect to the Lichen Area. If you are having trouble finding a big swamp area with many lightbulbs, look for the Blue Mushroom area as it will only feature a path that connects it to the Swamp-Lightbulb-Biome.

Once you find the Lichen biome, you are already inside the ruins. To reach the actual biome with the oddities like Thulecite and the Ancient Pseudosience Station, you will need to run through the Lichen area. Be careful of the dangers that lurk inside here, such as Slurpers that will latch on to your head.

Just keep walking as it is quite the way, and eventually, you will find the strange, red ground.

Each world is different

These are general rules that should apply in all worlds, but mind that each world generated differently so it might not look exactly the same in your world. Just keep your eyes open for the signs that are mentioned in this guide and you should eventually find it. For reference, here a picture of some parts of the cave along with some of the ruins explored. You will see that they are usually quite far away.

Rules inside the ruins

One of the most important aspects of the Ruins is the Nightmare Cycle. The Ruins has its own timer like day and night (altough it is not visible) and things inside the ruins change according to the time inside the Nightmare Cycle.

There are four phases of the Nightmare Cycle: the Calm Phase, Warning Phase, Nightmare Phase, and Dawn Phase. The entire cycle lasts 600 seconds.

The most important part for you is that depending on the time of the cycle, the so-called Nightmare Lights can be open or closed. Nightmare Lights (and also Nightmare Fissures) are light sources that cannot be destroyed or opened. The kind of light they emit is however extremely dangerous as drains your sanity. Depending on the deepness of the cycle, the sanity-loss becomes higher and higher and will quickly kill you. Additionally, the Nightmare Lights spawn Shadow Creatures (like those that spawn when you are close to insane) even if you are not insane.

Nightmare Light in Don't Starve Together

The Nightmare Cycle has 4 phases:

Calm Phase

  • Active for about 360 to 450 seconds (6 to 7,5 minutes)
  • The Nightmare Lights are closed and no shadow creatures will spawn
  • The runic turf is blue
  • No ambient sound can be heard in the background

Warning Phase

  • Active for only about 90 to 180 seconds.
  • The nightmare slights start slowly opening up
  • The color of the runic turf slowly changes to grey
  • The ambient sound is barely audible
  • The ancient statues begin to glow

Nightmare Phase

Nightmare Light in the Nightmare Phase
  • The Nightmare Phase is active for about 150 to 240 seconds.
  • The Nightmare Lights have opened up completely and the Shadow
  • Creatures will spawn.
  • The ambient sound is very loud
  • The ancient statues glow very brightly
  • The runic turf glows red
  • Earthquakes have the highest chance to occur during this phase

Dawn Phase

  • Active for only 60 to 150 seconds.
  • The Nightmare Lights are still open and the Shadow Creatures will still spawn
  • The ancient statues still glow (but weaker)
  • The runic turf has gone back to grey (like in the calm phase)
  • The background sound is very low again (similar to the warning phase)

It is extremely advisable to stay away from the Fissures and Lights during the Nightmare Phase (the other non-calm phases are dangerous too though). Also, you can craft a Thulecite Medallion to check the current state.

The Ancient Pseudoscience Station

Fully repaired Ancient Pseudoscience Station

One of the most intriguing and interesting oddities of the Ruins is the Ancient Pseudoscience Station. The Ancient Pseudoscience Station is a crafting structure similar to the ones you can build yourself, except that these can only be found in the ruins and not be moved. The recipes of the Ancient Pseudoscience Station are unique and related to Thulecite, the resource that you can find around the Ruins. Also, you can only craft those items next to the Ancient Pseudoscience Station. You cannot “learn” the recipe like with other items.

There are multiple Ancient Pseudoscience Stations to be found in the Ruins. Some of them will be broken and need to be repaired, but it usually requires a big amount of Thulecite and while that can be worth it, you should definitely explore the ruins and try to look for a station that is already repaired. Usually you should be able to find one (protected by multiple Damaged Bishops). The broken station will work too though, but it will only offer half of the recipes that are possible.

The layout of the Ruins

The ruins have a multiple different biomes that are all part of it. As mentioned, the Lichen fields for example, are already considered part of the Ruins. The others are:

  • Military Biome
  • Sacred Biome
  • Village Biome
  • Wilds Biome
  • Atrium Biome

The Atrium Biome is exclusive to Don’t Starve Together and is a very complicated and unique place in the Ruins with its own rules. It is very dangerous and can leave you locked in so you need to be careful. You can enter it by killing a Large Tentacle and jumping into the Tentacle Pillar Hole that it will leave. Due to its complexity, the Atrium will be covered in a separate guide.

Conclusion

The Ruins is not just one of the most dangerous places in Don’t Starve Together, it is also one of the most rewarding. Countless unique recipes with extremely powerful items can only be crafted here. There are plenty of individual Biomes to be explored, and some bosses and unique loot to be found.

If you have not explored the Ruins yet, definitely prepare yourself accordingly and then take a dive in as it will be very well worth it.
