Crystal Blade

It would be a nice addition to the 1.17 caves and cliffs update to add a new weapon. My idea for this is that you could collect the amethyst crystals, and using 4 of those, make 1 refined crystal. With 3 of those, you would be able to craft a crystal scythe, which would be about as powerful as a gold sword, with 800 durability. Its nothing too special except that it is a powerful weapon against the new Warden mob. It would do almost twice as much damage against the Warden, but when you are holding it within the proximity of a warden, it would be able to sense you.
