Scent

Prerequisites

Possess a nose.

Benefits

You can detect creatures by smell within a base range of 30 feet. If the creature is upwind, the range is doubled; if downwind, the range is halved. The base range is doubled for strong scents, such as smoke and rotting flesh, and tripled for overpowering scents, such as a skunk's musk or a troglodyte's stench. At 4th level, and every 3 levels higher, the base range is increased by 15 feet.

You cannot determine the creature's position until the creature is within 5 feet of you, but you can determine in which direction they are to you as a simple action. You can track creatures by scent using the Survival skill. The DC starts at 10, and increases by 2 for every hour since the creature has passed. The DC decreases by 5 for strong scents, and by 10 for overpowering scents. Wind speed and other scents can increase the DC, and multiple creatures with the same scent traveling together can reduce the DC. Tracking by scent ignores the effects of surface conditions and visibility.
