This data pack adds a taser which you can craft in the default crafting table, along with its refills. Right click to shoot, and upon impact it will electrocute its target - it does damage, disorients it by spinning it around, and makes it drop its weapons. There is a 5 second stun duration and also a shooting cooldown.

The crafting recipes are shown in the images, but for the 1.16 version of the pack (Use the provided alternate download link), an iron bar replaces the lightning rod.
