A lightweight Minecraft datapack that Restricts End Crystals so they can only be used in the End.
Crystals are fully disabled in the Overworld and Nether, preventing crystal PvP outside the End while still allowing them where they’re needed to resummon the Ender Dragon. Made for SMPs that want more balanced combat without removing End Crystals entirely.
