Diamond weapons are slayer equipment that requires 65 Attack (or 65 Magic for the staff) and 70 Slayer to wield. They are needed to kill Metallic experiments, as normal weapons do not work against them similar to Turoths and Kurasks. Diamond weapons are commonly used to slay metal dragons, especially the ones ranging from Mithril to Dragonite. Diamond weapons include: * Diamond longsword * Diamond staff * Diamond twinhammers Diamond bolts do not count as a diamond weapon, therefore Metallic experiments can't be killed through Ranged.
