SCP-513, The Cowbell
by Zcoper
SCP-513, The Cowbell is a Forge mob mod that adds a cursed bell and the tall figure it summons, built on the SCP universe.
What it does
An old rusted cowbell can be found naturally on the ground in the world. Picking it up is safe as long as it is carried and never rung. Ringing it, which happens when a player right-clicks the bell without sneaking, emits a loud sound that applies the Curse Bell effect to nearby players. The effect is the mod's central mechanic, and the mod's own story treats the cowbell as the source of the threat.
It watches from a distance, vanishes as it approaches, and reappears elsewhere. An eerie breathing sound announces its presence, and it grows more relentless while the player tries to sleep. The mod describes only one way to break the curse, which is death, and it notes that the entity can be sealed away by placing a Gel Block to imprison it.
The mod is published for Forge only, for 1.20.1, and requires Geckolib. Every player and the server need a copy of the mod. It was made with MCreator and is published under All rights reserved.
Key features
Cursed bell
Ringing the bell without sneaking applies the Curse Bell effect to players within earshot, while picking it up and carrying it is harmless.
Tall gray figure
SCP-513-1 appears to cursed players, keeps its distance, vanishes on approach and reappears at another spot.
Sleep disruption
The entity becomes more persistent while the player sleeps, and an eerie breathing sound signals that it is close.
Spawn behavior
The entity can turn up in the overworld without special setup, and only one instance exists in the world at a time.
