Echo Shards are items found in Ancient Cities in the Deep Dark biome. They are used to craft the Recovery Compass, which is an item that helps players locate their last known death location. The Recovery Compass is crafted by surrounding a compass with eight Echo Shards on a crafting table. Echo Shards are relatively rare and can only be found in chests within Ancient Cities, with a 29% chance of spawning inside a chest. Currently, the Recovery Compass is the only use for Echo Shards in Minecraft.
