Your Strength and Constitution Scores increase by +2

Some creatures possess blindsight, the extraordinary ability to use a non-visual sense (or a combination senses) to operate effectively without vision. Such senses may include sensitivity to vibrations, acute scent, keen hearing, or echolocation. This makes invisibility and concealment (even magical darkness) irrelevant to the creature (though it still can’t see ethereal creatures). This ability operates out to a range specified in the creature description.

• Blindsight never allows a creature to distinguish color or visual contrast. A creature cannot read with blindsight.
• Blindsight does not subject a creature to gaze attacks (even though darkvision does).
• Blinding attacks do not penalize creatures that use blindsight.
• Deafening attacks thwart blindsight if it relies on hearing.
• Blindsight works underwater but not in a vacuum.
• Blindsight negates displacement and blur effects.

Blindsense lets a creature notice things it cannot see, but without the precision of blindsight. The creature with blindsense usually does not need to make Perception checks to notice and locate creatures within range of its blindsense ability, provided that it has line of effect to that creature. Any opponent that cannot be seen has total concealment (50% miss chance) against a creature with blindsense, and the blindsensing creature still has the normal miss chance when attacking foes that have concealment. Visibility still affects the movement of a creature with blindsense. A creature with blindsense is still denied its Dexterity bonus to Armor Class against attacks from creatures it cannot see.

Using all of your actions this turn you travel at up to 5 times your base land speed in a straight line, you can terminate the run early but you can't turn. While running you provoke attacks of opportunity normally for passing through threatened squares. Trying to sustain the run requires con checks for every round beyond the first with a +4 per round spend running the DC starts at 15, each round spent running deals 1 con damage.

This extraordinary ability lets a creature detect approaching enemies, sniff out hidden foes, and track by sense of smell.

A creature with the scent ability can detect opponents by sense of smell, generally within 30 feet. If the opponent is upwind, the range is 60 feet. If it is downwind, the range is 15 feet. Strong scents, such as smoke or rotting garbage, can be detected at twice the ranges noted above. Overpowering scents, such as skunk musk or troglodyte stench, can be detected at three times these ranges.

The creature detects another creature’s presence but not its specific location. Noting the direction of the scent is a move action. If the creature moves within 5 feet (1 square) of the scent’s source, the creature can pinpoint the area that the source occupies, even if it cannot be seen.

A creature with the Survival skill and the scent ability can follow tracks by smell, making a Survival check to find or follow a track. A creature with the scent ability can attempt to follow tracks using Survival untrained. The typical DC for a fresh trail is 10. 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. The ability otherwise follows the rules for the Survival skill in regards to tracking. Creatures tracking by scent ignore the effects of surface conditions and poor visibility.

Creatures with the scent ability can identify familiar odors just as humans do familiar sights.

Water, particularly running water, ruins a trail for air-breathing creatures. Water-breathing creatures that have the scent ability, however, can use it in the water easily.

False, powerful odors can easily mask other scents. The presence of such an odor completely spoils the ability to properly detect or identify creatures, and the base Survival DC to track becomes 20 rather than 10.

Dense fur protects you from the cold.
