Your senses allow you to notice fine details and alert you to danger. Perception covers all five senses, including sight, hearing, touch, taste, and smell.
Check
Perception has a number of uses, the most common of which is an opposed check versus an opponent's Stealth check to notice the opponent and avoid being surprised. If you are successful, you notice the opponent and can react accordingly. If you fail, your opponent can take a variety of actions, including sneaking past you and attacking you.
Perception is also used to notice fine details in the environment. The DC to notice such details varies depending upon distance, the environment, and how noticeable the detail is. The following table gives a number of guidelines.
Perception is also used when a Character needs to look for something. Searching a room for something out of the ordinary or clues. A good or successful perception may be used to help find missing tracks in the wild but not used to follow them or to learn from those tracks. Just because you see foot prints in the ground doesn't mean you know who/what, when and where they are headed. That information requires a Survival check. The same goes for investigating a crime seen. Perception can be used to help look through the room if you do not have the Study skill. But being able to find things that are not obvious to a Character of its significance is not possible with using the skill.
Action
Most Perception checks are reactive, made in response to observable stimulus. Intentionally searching for stimulus is a move action.
Try Again
Yes. You can try to sense something you missed the first time, so long as the stimulus is still present.
