Aerial creatures are native denizens of the Elemental Planes of Air, and they possess unique adaptations to help them survive there.
This template can be applied only to a non-outsider with none of the subtypes that follow: air, cold, earth, fire, or water. An aerial creature’s CR increases by 1 only if the base creature has 5 or more HD.
Rebuild Rules: Type gains the air subtype; Senses gains darkvision 60 ft.; Defensive Abilities gains DR and resistance to electricity as noted on the table below; Speed gains a fly speed equal to its highest speed with perfect maneuverability (maximum fly speed of 10 feet per HD); Attacks gains bonus electricity damage as noted on the table below on attacks with natural weapons and metal weapons.
