Slender

The Slender entity appears in the world and walks toward the nearest player. Within a set distance it changes behavior: at seven blocks it applies blindness and slowness, followed by nausea, and at closer range it runs at the player and tries to kill them. Some Slenders despawn after a time, and the mod includes a variant called Slender Paranoia that is invisible and moves toward players until it collides with them.

Slenders spawn in groups of five, with one of them able to kill the player while the others only scare them. When a Slender dies it drops an item called a finger, which can be crafted into a finger stick. The stick behaves like a hoe and loses durability per use, and its recipe needs a diamond. The mod requires Geckolib, and it runs on client and server, so the server and every player need it.
