Controlled Insomnia
by HexagonNico
Controlled Insomnia changes when phantoms spawn, so they appear only for players who have the Insomnia effect, applied by a potion brewed from eye blossom and ender eye.
What it does
Phantoms normally spawn at night on players who have gone too long without sleeping. Controlled Insomnia keeps that link but limits it: phantoms spawn only around players who carry the Insomnia effect, and a player with the effect can sleep in a bed as in vanilla. Phantoms spawn in the sky at night, one to two minutes after the effect is applied, so the threat is tied to a chosen player rather than to the clock.
The Insomnia potion is brewed from an eye blossom and an ender eye, with the recipe depending on the Minecraft version. The mod requires Fabric API on Fabric. It runs on the client and the server, so the server and every player need the mod. Files cover 1.21.1 – 1.21.10 for Fabric, Forge and NeoForge, with the latest build, 21.10.0, published for 1.21.10 on 2026-01-17.
