Autocast

Autocast is an option of many Magic weapons, primarily staves that can be activated on the combat screen section of the interface. This attack option causes players to automatically cast a selected spell when they attack, as opposed to manually selecting the spell and its target each time you wish to cast it. The spells that can be autocasted vary between magic weapons, but they can be selected by clicking on the book found on the combat screen when a magic weapon with the autocast ability is selected. Once autocast has been selected, a player will continue casting spells as their default attack as long as they wield the staff and have the correct amount of runes. Regular staves, battlestaves and croziers can autocast combat spells from the standard Spellbook, the Ancient staff and the Master Wand can autocast the Ancient Magicks, and the Slayer staff can autocast Crumble undead as well as giving the ability to cast the Magic Dart spell. The Void Knight mace can autocast the Claws of Guthix spell, making it the only mace with the autocast ability, and making Claws of Guthix the only one of two God spells with the autocast ability (aside from the Staff of the Dead with Flames of Zamorak). No teleportation, alchemy, curses, or enchantment spells can be autocasted.
