Heat (Ex): A fire drake's red-hot body deals 1d6 points of extra fire damage whenever it hits in melee or when grappling, during each round that it maintains a hold.

Creatures or weapons that strike a fire drake also take this damage (no save allowed).

Skills: Fire drakes have a +4 racial bonus on Search checks.

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.
