Shadow Creatures

Shadow Creatures are hostile mobs and hallucinations of the player. They will turn "real" if the sanity is low enough.

These are hallucinations. No mob attacks them and none of them attacks any mob expect for the player.

Crawling Horror
The crawling horror is the first shadow creature, that will spawn.

It is very slow, so easy to outrun , thought it can see the player from more then 100 blocks away and through walls.

Crawling Horrors teleport, if hitted by the player with a 85% chance.

They will growl quietly, if approached.

It will not enter water, so one can try to find an ocean to outrun it.

Boogeyman
The Boogeyman is a little bit stronger than the crawling horror.

It will always be aggressive, so there is no alert , when it spawns ( unlike Crawling horrors , who will spawn passive at the beginning )

Boogeyman can enter water and swim in it.

Boogeyman is as fast as a zombie.

Shadow Spider
Shadow Spiders are very dangerous shadow creatures, and will jump to their enemy simular to regular spiders.

Swimming Nightmare
The swimming Nightmare is a shadow creature, that only spawns on water blocks.

It can not leave the water.

The swimming nightmare will destroy a boat by contact.

They are not affected by the Trident enchantment, as they aren't aquatic mobs

Eyes
If Sanity drops under -40, Eyes will spawn in a Light Level of 5 or lower.

They can spawn at night, but also in caves. They are also able to spawn in the nether, the end and other dimensions.

They will not affect the gameplay in any way except for scaring the player.
