Aerial Simple Template Graft
Aliens
Aerial creatures are native denizens of the Elemental Plane of Air, gas giant planets, or similar landless environments, and have unique adaptations to help them survive there.
Grafts: Add the air subtype graft (fly speed should equal creature’s fastest movement speed).
Traits: Half of the damage dealt by its natural attacks becomes electricity damage; if the creature is from the Elemental Plane of Air, it gains the extraplanar subtype when it isn’t on that plane.
