Void blade

A blade made that harnesses dark energy to slay its foes in battle. This blade would better than netherite and would have +2 blocks of reach. Also when you shift and hold right click you send out a dark wave of energy which gives you the wither effect, though this has a large cooldown and drains the blade’s duration. To craft this blade you would need echo shards, a new rare metal called scullrite which would be found rarely near bedrock, And a stick.
