The Arrow of Weakness (0:11) is a tipped arrow that, when fired from a bow, afflicts its target with the Weakness status effect for 11 seconds. This effect reduces the damage dealt by melee attacks from the afflicted entity, making it particularly useful in combat situations where reducing an opponent's attack strength is strategically advantageous. It is crafted by combining a regular arrow with a Potion of Weakness in a crafting grid or using a cauldron filled with the potion.
