Autocast

Autocast is an ability granted by many magic weapons that can be activated on the combat screen section of the interface. This ability makes a player's attack the automatic casting of a selected spell, as opposed to manually selecting the spell and its target each time you wish to cast it. The spells that can be autocast 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.
