Scent (Ex)

This ability allows the creature to detect approaching enemies, sniff out hidden foes, and track by sense of smell. Creatures with the scent ability can identify familiar odors just as humans do familiar sights.

The creature can detect opponents within 30 feet by sense of smell. If the opponent is upwind, the range increases to 60 feet; if downwind, it drops to 15 feet. Strong scents can be detected at twice the ranges noted above. Overpowering scents can be detected at triple normal range.

When a creature detects a scent, the exact location is not revealed—only its presence somewhere within range. The creature can take a move or attack action to note the direction of the scent. If it moves within 5 feet of the source, the creature can pinpoint that source.

A creature with the scent ability can follow tracks by smell, making a Wisdom check to find or follow a track. The typical DC for a fresh trail is 10 (no matter what kind of surface holds the scent). This DC increases or decreases depending on the strength of the quarry’s odor, the number of creatures being tracked, and the age of the trail. For each hour that the trail is cold, the DC increases by 2. The ability otherwise follows the rules for the Track feat. Creatures tracking by scent ignore the effects of surface conditions and poor visibility.
