Any feat of the [Elemental] type can only be taken by Outsiders and Elementals of origin on with the Elemental Planes, or with ancestors from the Elemental Planes (such as Genasi), and by creatures from other planes with a specific close affinity for an elemental plane (sources of such affinities will be labelled). All Genies, regardless of type, may also take [Elemental] Feats. Many [Elemental] feats require specific subtypes.
