Nightmare Lights are light sources found within the Ruins. They cannot be opened or destroyed with a Hammer. Instead, the amount of light they emit depends on the current state of the Nightmare Cycle that the Ruins are in; the more extreme the magical state, the more the Nightmare Lights open up.

Nightmare Lights drain the player's Sanity when they are open and if the player is near. The actual magnitude of the drain depends on how much light is coming from the Nightmare Lights (how "open" they are). During the Warning phase they will drain 600 sanity/min, while in the Nightmare phase they will drain 900.

Shadow Creatures will appear around the lights, even if the player is not insane. The Shadow Creatures only appear during the Nightmare phase and are hostile to the player. Once the Nightmare Cycle is completely over, the creatures will despawn.

Nightmare Fissure

Nightmare Fissures are objects that appear in the Ruins and rarely in Caves, more specifically, on Stalagmite Terrain. They act identical to Nightmare Lights. Depending on the phase of the Nightmare Cycle, they emit more or less light - the greater the light radius, the higher the chance of spawning Shadow Creatures. 

Each Nightmare Fissure can spawn only one Shadow Creature at a time, either a Terrorbeak, Crawling Horror or a Lurking Nightmare. If a player attacks one of these Shadow Creatures, all nearby Shadow Creatures will attack the player in a group. Once the fissure is closed, any spawned Shadow Creatures will despawn.

When the Shadow Rift is activated, approaching a Nightmare Fissure while a Shadow Rift is active will generate a Dreadstone Outcrop surrounded by Miasma, provided there is no currently active outcrop and no others have been destroyed within the last three days. Additionally, Ink Blights will spawn when the player comes near.

After activating the Archive Switch in the Ancient Archives, multiple Nightmare Fissures will emerge at the entrance of the Lunar Grotto biome, accompanied by Nightmare Ramparts. Although these Nightmare Fissures can also spawn Shadow Creatures, they will not transform into Dreadstone Outcrops, nor will they spawn Ink Blights.

Tips

• Nightmare Lights can only spawn up to two shadow creatures per cycle, while Fissures can only spawn one.
• While wearing the Bee Queen Crown, Nightmare Lights increase sanity instead of decreasing it. Fissures are not affected by the Crown.
• The Prefabs of Nightmare Fissures in Ruins is "fissure_lower", in Stalagmite Terrain it is"fissure", and the one created by Nightmare Rampart is "fissure_grottowar".
• It is advisable to put a Sign or other item with a Map icon near the Nightmare Fissures to mark their locations, since these are the best places to farm Nightmare Fuel.

Trivia

• Nightmare Fissures were introduced in the Six Feet Under update.
• The Nightmare lights are fueled by Nightmare Fuel extracted from unknown depths below. This is a major example of the excessive use of Nightmare Fuel by the Ancients that led to their downfall.
