Given that some circumstances prohibit any real chance of success and many actions can be completed automatically with the right time, materials, and capability a GM may rule that an action has an obvious outcome as success or failure without any check. Obvious results may bypass strict rules in favor of a reasoned outcome; i.e. a target asleep may be killed by a dagger, though the weapon could not normally kill based solely on the damage it does in combat. If unsure, consider obvious outcomes to represent an Extraordinary Success.
