Echo Shard Weapons and Tools

A lineup of new weapons and tools made out of echo shards! Also, echo shards shouldn't just be found in chests. They should be like dripstone. I think Echo Shards hanging from the ceiling of the deep dark would make it creepier. 

Also, I have an idea about an item called the echo staff! Basically, it's just a staff made of an echo shard and copper. How it works is it can redirect sound to another location, also it can make a sonic boom similar to the attack used by the warden. All the weapons and tools made with echo shards are generally resistant to skulk blocks.
