New Hidden Combat Challenge: "Conquering the Gloom"

Description:We need more ultra-hard, hidden combat achievements for end-game players. I propose a new hidden challenge advancement related to cave exploration.The Challenge: To unlock it, the player must defeat a Shadow Stalker while being completely under its continuous Blindness effect (standing within its 5-block danger zone).Why it's fun: Since the player is completely blinded, they must rely entirely on 3D game audio, listening to the stalker's creepy whispers and its helper bats' wing-flaps to aim their strikes. It would be one of the hardest and most rewarding achievements in the game, granting a massive purple challenge notification and a huge amount of XP upon completion!
