Listen can be used to check if a player hears a certain sound they are listening for, such as discussion on which they are eavesdropping. It can also be used to see if they are paying attention to what they are listening to, such as whether or not they hear the sound of a swarm of bees approaching. It is also against a creature using stealth in the players presence

This deals with your ability to notice details or a creature using stealth in your vicinity. It measures your general awareness but also your visual acuity

Task Perception Difficulty
Notice a visible creature in plain sightEasy
Notice an obvious detailEasy
Notice that something has changedModerate
Notice a subtle or hidden detailHard
Notice a creature attempting to hide from youOpposed by Stealth

Your visual acuity is your ability to see details at a distance. The measurement 20/20 signifies normal vision, that you are able to see details at 20 feet that a normal human can see at 20 feet. 40/20 would mean that at a distance of 40 feet, you can see the same detail that a normal person sees at 20 feet

Each rank in Perception strengthens your visual acuity by 1 foot (Maximum 20). For example, a player starting with normal vision, who gains 10 ranks in Perception would have 30/20 vision. Players are assumed to start with 20/20 vision unless otherwise noted in their character description

Action: Reactive Spot checks are not part of an action
Try Again: Yes, if the target object has changed, moved, or conditions have improved since the last check
