This epic spell transforms all creatures in the area into incorporeal and imperceptible shadows. Non-sight-based senses are ineffective at detecting the subjects and the spell also makes all subjects invisible to all sight, including darkvision. Any gear the subjects of the spell are carrying melds into the subjects' new forms and vanishes as well, making the subjects completely invisible. The spell persists even if any of the subjects attack another creature.
