castlEeffct
by jr6i
castlEeffct adds more than 80 visual kill effects that play when an entity dies, client-side only, for Fabric on 1.20.1.
What it does
Kill effects appear on the client when a mob or player is defeated. The catalog lists over 80 of them, grouped into categories such as Advanced Tech and Magic and Original. Some effects bend the scene, including black hole and judgement visuals, while others are lighter, such as anvils raining down or pistons squishing their targets.
Rapid kills are tracked by a combo system, and the mod can show kill marks, floating particle text like GG, KO and REKT, and temporary glowing rings on the ground where enemies fell. Effects also change with the biome, so a kill in snow or water looks different from one in a desert. Volcanic and nature-themed effects are included. The mod is a client-side Fabric mod, so the server does not need it and players install it alone.
The mod requires Fabric API on the loader it targets. Files are published for Fabric only, and the latest build, 1.0.0, was published on 2026-06-13 for 1.20.1. The code is under All rights reserved, so the mod is not open source.
