Kill Effects

Client-side cosmetic kill effects for Minecraft (Fabric).

Add visual effects whenever an entity dies, including particle bursts, fireworks, lightning, shockwaves, ghosts, sounds, and more. Create your own presets, combine multiple effects together, and customize everything through an easy in-game editor.

Works on any server and never affects gameplay.

KillFX Showcase

Features

Custom Kill Effects

Mix and match effects to create your own unique kill animations:

  • Particle Bursts
  • Fireworks
  • Visual Lightning
  • Shockwaves
  • Ghost Effects
  • Glow Flashes
  • Custom Sounds

Custom Critical Hit Particles

Replace Minecraft's default crit particles with your own PNG images.

Simply place PNG files into:

config/killfx/crit/

Then select them in-game and customize:

  • Size
  • Opacity
  • Colors
  • Rotation
  • Particle Count
  • Trails
  • Rainbow Effects
  • Random Texture Selection

Supports virtually any PNG resolution and automatically scales textures to fit your chosen particle size.

Entity Filters

Choose exactly when effects should play:

  • Any Entity
  • Players Only
  • Hostile Mobs
  • Passive Mobs
  • Custom Whitelists & Blacklists

Presets

Save, import, export, and share your favorite effect combinations.

In-Game Editor

Open the editor with:

  • K (rebindable)
  • /killfx

Customize every effect with live previews and instant updates.

100% Client-Side

No server plugins required.

Install the mod and start seeing effects immediately on any singleplayer or multiplayer world.

  • Any Death
  • Local Player Kill
  • Damaged By Local Player
  • Other Player Death
  • All Visible Deaths

Detection Methods

KillFX combines four independent systems for maximum reliability:

  • Health Monitoring
  • Entity Unload Detection
  • Death Event Tracking
  • Server Death Message Parsing

Effects work consistently even on PvP servers and plugin-heavy networks where normal death packets may never reach the client.
