Insanity Creatures

Crawling Horrors are neutral Monsters that become hostile when the player goes insane (Sanity Meter reaches 0). They become more easily visible the lower the players Sanity level drops. They will spawn anywhere although some only spawn at night. After they are attacked, they will take damage disappear in a puff of smoke, before reappearing, again close to the player. Once provoked, either by the player going insane or by attacking them, they chase and try to attack the player. They can be attacked with Normal Weapons, but are more effectively killed by a Dark Sword, a specialised weapon for this mob. There is also Night Armour, that reduces the damage taken from a Crawling Horror. Upon being killed, Crawling Horrors drop Nightmare Fuel. There are various types of Crawling Horrors, one who "stalks" the player by there campfire at night (This may be the shadow of the Grue, as one pair of eyes in the darkness look similar to theirs.), one who is "harmless" and disappears when the player draws near, and a large one that "roams" around everywhere.

The players Sanity Level is reduced by being around Crawling Horrors.

Trivia

 * Crawling Horrors will go straight through walls.
 * They become less and less transparent the more insane the player becomes.

Bugs

 * When reappearing, they may appear on the ocean, thus stuck.
