Passive Perception is a system in D&D 5e that allows players to see what other players are seeing. This system is similar to the Blind Spot system in other RPGs, but it is more specific to D&D. Passive Perception works by reading the emotions and thoughts of other players, and then using this information to determine what actions a player should take. There are two ways that passive perception can be used: as part of an action tree and as part of a passive ability. As part of an action tree, passive perception can be used to determine which abilities a player should use when they encounter an enemy or situation. For example, if a player has the Passive Perception ability and they encounter an enemy who is hiding in shadows, they can use their reaction to see if the enemy is hiding in shadows or not. If they find out that the enemy is hiding in shadows, they can then use their action to try and catch theenemy before he or she can escape. As part of a passive ability, passive perception can also be used when a player has no action available to them. For example, if a player has the Passive Perception ability and they are trying to sneak past an opponent, they may need to use their reaction time to see if their opponent is watching them from behind cover or not. If they find out that their opponent is watching them from behind cover, they can then try and take advantage of this by sneaking up on their opponent before he or she sees them coming.
