Anvil Dropper

This custom challenge will summon an anvil 10 blocks above you every 2 seconds, forcing you to either seek shelter, or be on the move constantly.

To start the challenge, simply run /trigger anvil_active and start running.

This data pack was originally made for version 1.17, but it still works up to 1.20.4 (and probably later versions if you're reading this in the future).
