Chill Metal (Su): The ice paraelemental's chill metal power functions like the druid spell of the same name, except that it affects everything within a 30 ft. radius (DC 22). As with the spell, it takes 3 rounds for affected metal to reach the freezing stage. Once it does, it remains at that stage until the ice paraelemental takes a standard action to end the effect. The metal returns to its starting temperature 2 rounds later, just as with the spell.

Cold Subtype (Ex): Cold immunity; double damage from fire except on a successful save.

Ice paraelementals are patient combatants, often waiting for foes to come to them. Larger individuals may pretend to be flat-footed, delaying their action in hopes of luring opponents within reach of their many attacks of opportunity. (All ice paraelementals have the Combat Reflexes feat.) In any case, ice paraelementals move to maximize the number of opponents within the radius of their chill metal attack then maneuver to outlast the enemy (who has likely taking damage from freezing weapons and armor).

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).

Cold Subtype

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