An extended action is an action which takes more than an instant to resolve. For example, a character may wish to search a library for specific occult lore, repair an engine, or break down a door. The Storyteller, Revised Storyteller and Storytelling systems all contain rules for extended actions. These rules are generally only used when it is important to know how long a task takes to complete, as well as how well it is executed; time-consuming actions in which the character may take as long as she likes are resolved in the normal way. Extended actions are sometimes also contested actions.
