The Emerald upgrade of the Strange Rune Bow, increasing heavily its accuracy, making it the most accurate bow by far. Only obtainable in the Hidden Mines of Al-Aziz by handling a Strange Rune Bow and a Qualis Gem. The bow is not used by any troop, so its up to the player for this bow to exist.
Note: in 3.8.4 and previous versions, damage was 42, accuracy 91, speed 100, shot speed 85 and Power Draw requirement 8.
