A datapack I made for Minecraft that adds an OP (overpowered) horse to the game.
The horse is spawned if you combine netherite leggings and a saddle in a smithing table.
Go to releases and download the latest release (v2.0-1.17)
Extract the zip and click through until you get to the next zip file.
Move the zip into .minecraft/saves/[YOUR WORLD]/datapacks
In the Minecraft console, type /reload
