To wield this powerful sword you must complete the Lost City quest and have level 60 attack. Upon completion of the quest you can purchase this item in the Zanaris marketplace (requires one cut diamond to enter) for 100,000gp. The Dragon Longsword's special attack is an attack that does a higher damage than an average attack. It takes up 1/4 of the Special Bar. Like all dragon items, these cannot be made by players.
Effect: Cleave is much more powerful and therefore, inflicts greater damage to your opponent.
