Nightmare Fuel

Nightmare Fuel is a Refined Item used in Dark and Ancient Magic. Most Shadow Aligned mobs drop it when killed, it can be prototyped with a Prestihatitator and 4 Dark Petals, or 
Wilson can craft it from 2 Pure Horror if the player has mastered Shadow Courtier.
Mobs that drop Nightmare Fuel include:
* Shadow Creatures
* Beardlings
* Damaged Clockworks
* Shadow Splumonkeys
Objects that drop Nightmare Fuel include:
* Graves - when dug using a Shovel
* Touch Stone - when resurrected
* Ancient Statues - when mined with a Pickaxe
* Pig Heads - when hammered on a full moon
* Ornate Chests (25% chance) & Large Ornate Chests (75% chance)
Nightmare Fuel is used to craft various Magic items. It is also used to fuel Night Lights, Maxwell's Codex Umbra, the Magiluminescence and other objects. Chester can transform into Shadow Chester by placing Nightmare Fuel in each of his nine inventory slots on a Full Moon.
__NOTOC__
== Gathering ==
Nightmare Fuel is typically acquired by going insane and killing Shadow Creatures. See that article for details.
One could pick Evil Flowers and craft the fuel from Dark Petals. Picking each costs 5 sanity. Also, Evil Flowers have a negative sanity aura, so just moving to pick one costs sanity. Evil Flowers do not respawn and Homeless Bee propagation is severely limited. Each nightmare fuel crafted this way costs more than 20 sanity and many fuel are needed to craft the typical array of useful magic items. The character will need to restore their sanity multiple times during this process or end up insane and fighting shadow creatures anyway.
One could trap a number of Rabbits, lower sanity below 40% (so the Rabbits turn into Beardlings), then murder them in inventory. This yields Monster Meat and Beard Hair in addition to nightmare fuel, but murdering too many innocent creatures quickly can advance the player's naughtiness enough to spawn Krampus.
The Ruins are extremely dangerous, but filled with things that drop nightmare fuel. In , when the Nightmare Cycle ends, all of the Shadow Creatures that spawned from the Nightmare Lights in the Ruins and Nightmare Fissures in the Caves will despawn and drop Nightmare Fuel. In they tend to despawn without dropping anything and must be killed before the cycle ends in order to drop fuel.

In the Hamlet DLC, Nightmare Fuel can also be acquired by killing the Ancient Herald and a low chance from A Smashing Pot. Nightmare fuel can also be given to the End's Well for 1-3 purple gems each, as many times as you want for an endless supply of purple gems.

== Usage==
== Trivia== 
* The term "nightmare fuel" is a common phrase on the Internet used to describe works of fiction, or scenes therein, that are extremely likely to disturb and/or frighten the audience.
* When dropped on the ground, Nightmare Fuel appears as pulsing goo.
*Unlike Beardlings, Beardlords do not drop Nightmare Fuel.
*Maxwell, upon examining the Ancient Guardian, says "My my, the fuel has changed you." This implies that prolonged exposure to Nightmare Fuel can alter creatures in some significant way. This is also proven by the ability to turn Chester into his shadow form via Nightmare Fuel.
*According to Webber, Nightmare Fuel feels cold. However, according to Willow, Nightmare Fuel feels warm. This may indicate it has different properties to different people.
*In DST, Shadow Creatures no longer drop Nightmare Fuel at the end of the Nightmare Cycle. It was stated by the developers that the drops in the original game were caused by a bug and not intended.
