Smoke Claws (Ex): A smoke paraelemental can engulf opponents by moving on top of them. It fills the air around one opponent smaller than it is without provoking an attack of opportunity. The target must succeed at a Fortitude save (DC 29) or inhale part of the creature. Smoke inside the victim solidifies into a claw or talon and begins to rip at the surrounding organs, dealing double the paraelemental's claw damage automatically. The affected creature can attempt another Fortitude save each subsequent round to cough out the semi-vaporous menace.

Smoke paraelementals use their great speed to good effect in combat, flying circles around their land-bound foes.

Air Subtype

This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane Air. Air creatures always have fly speeds and usually have perfect maneuverability (see the section on Movement).

Fire Subtype

A creature with the fire subtype has immunity to fire. It has vulnerability to cold, which means it takes half again as much (+50%) damage as normal from cold, regardless of whether a saving throw is allowed, or if the save is a success or failure.
