Start Full-Round Action

Want to take a full-round action, but only have a standard action left? The little-known "start full-round action" standard action lets you start undertaking a full-round action, which you can complete in the following round by using another standard action. You cannot use this action to start or complete a full attack, charge, run, or withdraw. This action can be handy if you want to start casting a full-round spell after taking a move action, or during a surprise round. Another option is to move, cast a full-round spell, then move again.
