Ephemeral Wither Skulls
by sui_ke
Ephemeral Wither Skulls caps how long a Wither Skull can exist, removing each skull six seconds after it appears, which helps worlds already crowded with skulls from earlier play.
What it does
The mod sets a six-second lifetime on every Wither Skull. Skulls that outlive that limit are removed, and the normal behavior of the Wither itself is left unchanged. Fabric API is required, and the mod is installed on the server, while clients may add it or leave it out.
A world that already holds a large number of Wither Skulls, including skulls saved in chunks from before the mod was added, is cleaned up when the mod loads. Removal speed depends on how many skulls are present. In the author's tests on an i7-9700 CPU, 5,000 skulls were removed instantly and 30,000 took about four minutes to clear completely. Once the mod is installed, Wither Skulls summoned with commands disappear quickly, so long-lived skull setups will not work the same way.
The mod is published for Fabric only, across 14 release versions, 1.18.2 – 1.21.5. The latest file is 1.1 for 1.21.5, published on 2025-04-14. It is released under the MIT License and is not open source.
Key features
Six-second skull lifetime
Every Wither Skull is removed six seconds after it is created, which limits how many skulls can build up.
Normal Wither behavior kept
The Wither keeps firing skulls as usual; only the time those skulls remain in the world is shortened.
Cleanup of saved skulls
Skulls already stored in saved chunks are removed when the mod loads, so an existing world is cleaned up.
Removal speed by quantity
Cleanup is quick for a few thousand skulls and takes minutes for tens of thousands, according to the author's tests.
