Description: Creatures with perfect smell can detect and identify non-stealthed creatures within 120 feet without needing to roll a Perception check. Detected creatures need not be within line of sight, but a line of effect must exist, and the path of that effect cannot exceed the 120 foot range. Detected creatures do not have concealment from a creature with Perfect Smell. If a creature is stealthing, the creature with Perfect Smell must make a Perception check to perceive them, with a DC equal to the stealth check result of the stealthing creature. However, Perfect Smell grants a +5 circumstance bonus to the sniffing creature's Perception checks to detect stealthed creatures. Invisibility grants no benefits to a stealthed creature against this check.
Perfect smell does not provide any knowledge of a detected creature other than its location and whether nor not it is familiar. However, it allows the detecting creature to make lore checks against unfamiliar creatures, and recognize individuals it has previously encountered.
Wind does not interfere with this ability.
A creature with perfect smell may also use the Survival skill to follow tracks by smell, making a Survival check to find or follow a track. The typical DC for a fresh trail is the lowest maneuver defense from among the creatures being tracked. The DC increases or decreases depending on how strong the quarry's odor is, the number of creatures, and the age of the trail. For each hour that the trail is cold, the DC increases by 2. Creatures tracking by keen scent ignore the effects of surface conditions and poor visibility. The ability otherwise follows the rules for the Survival skill in regards to tracking.
A creature with perfect smell that can also breathe underwater can detect and identify other creatures by scent in a 1 mile radius underwater.
