Slayer's staff

The Slayer's staff is sold by Slayer Masters. It requires level 50 Magic and level 55 Slayer to wield and is required for the Magic Dart spell. The staff can can also autocast Magic Dart, Crumble Undead, and the 4 elemental Wave spells. The Slayer Staff is popular for training magic since it can autocast the Crumble Undead spell unlike other magical staves, except the Void Knight mace. Other players also use it for doing the Barrows mini-game and killing Dagannoth Kings with the Magic Dart spell. Also it is the most powerful (in damage/minute) weapon for 1 attack, so it is a popular choice for obsidian maul pures in the making (if they have 55 slayer and 50 magic).
