Downloading

  • Find the releases section on the right panel
  • download the .jar file into your mods folder (for 1.21.11 only!!)
  • make sure you have the mods fabric api and mod menu installed

Usage

Go in game, get an axe and mace and press your stun slam hotkeys, it will automatically register inputs based on your hotbar slot.

This mod is designed with attribute swapping in mind and only counts tick perfect stun slams (for now).

The hard white lines are the times a tick happens on the client. The soft white lines at the bottom are when every client frame is rendered.

Some options are togglable with mod menu eg size.

The /stunslam toggle command can toggle HUD visiblity quickly.

Stun Slam Simulator server crashes on startup – what to do?
