This datapack adds the Echo Nail, an item found in ancient city chests that when held in your offhand increases your attack range and block breaking and placing range by 1 block.
Works for 23w51a (so far, and I cannot promise I'll give it support)
Known Issues: Since the datapack replaces the Vanilla Ancient City loot table with mine, using it with other datapacks/mods that add items to the loot table may result in some items not appearing.
