Butcher's Deerhunting (Yi Xi)

A stalking entity is the core of the mod. It follows the player, disappears when the player looks away or moves off, and never lets go of its presence. The creature is meant for singleplayer worlds, though it also works in multiplayer. Its tone is intentionally unsettling, with a nausea effect of high amplitude that some players may find uncomfortable.

The mod also adds weapons and tools made from a new steel material. Players fabricate the steel themselves through processes introduced by the mod, and the tools deviate from the usual toolset design in a few ways. The entity can be defeated, but only by using the right cards and playing to its known weaknesses, so the fight depends on the player's preparation.

Worldgen adds a biome that expands the existing cherry blossom biome, along with a butcher house structure that generates in the world. The server and every player need the mod installed. It is published for NeoForge only, across 1.21.8 – 1.21.11, with 1.0.3 for 1.21.11 as the latest file, and is released under All rights reserved, so it is not open source.
