Prerequisite(s): Knowledge (planes) 10 ranks
Benefit: Casting a spell augmented with this feat causes the spell to manifest in the Ethereal Plane as well as the Material Plane. This causes it to affect all incorporeal and ethereal creatures in the area of effect in addition to all material creatures in the area of effect. This metamagic feat cannot be applied to summoning spells.
