The Deflecting Hard Tear is a powerup in Shadow of the Erdtree that enhances spontaneous guard, turning the game into Sekiro by allowing players to time their blocks perfectly to avoid damage and fill up the enemy's stagger bar. It works even without a shield, making it effective with two-handed or paired weapons. It also allows for guard counters and empowered R2 attacks. The powerup is a game-changer when facing tough enemies and can help make the game easier for those struggling with its difficulty.
