Head Hunter

The "headhunter" datapack for Minecraft uses the 1.21+ loot table system, so player heads fall to death. It doesn't use summon but modifies the loot table of the player and allows them to get their head. This is an ideal datapack for use on multiplayer servers or custom worlds where players can collect the heads as trophies, or decoration, or for trading purposes. It's easy to install. It's compatible with newer versions of Minecraft and changes the whole dynamic on death.
