For this to work you need the Origins Mod. Fabric/Forge

This is a Datapack, not a Mod.

Adds a Sandworm origin which can move faster on sand and gets blindness on stone

In the future I intend to add other origins that have a big impact on your game and beeing more of a handicap than only an upgrade to the base human
