Abnormalities is a Forge horror mod for 1.20.1 that adds entities, world corruption and random atmospheric events to a survival world.

ForgeClient and serverMIT LicenseOpen source1.20.1

What it does

Entities stalk, watch, mimic and punish the player, and terrain anomalies such as pillars, farlands and bedrock cubes can appear in the world. Random horror events trigger over time, with screen shakes and sounds that play at the master volume, so the scares are hard to avoid. The author describes the mod as built for players who want a tense, unsettling experience, and the in-game configuration screen lets a player lower spawn weights or disable specific features.

The mod is released under the MIT License, and its source code and an issue tracker are linked from the project. It runs on Forge 1.20.1 and the environment is client and server, so the server and every player need it. The config can be edited in game or through the abnormalities.toml file in the config folder.
