Good memory. 
Incorporeal Jaunt (Su): A phaser sheen can become incorporeal as a swift action. It can become corporeal again as a swift action or a standard action. Unlike most incorporeal creatures, a phaser sheen may make grapple attacks against other incorporeal creatures, and they can be grappled by other incorporeal creatures. Both the sheen and its opponents use their Charisma modifiers when performing grapple checks while incorporeal. Starting on its fourth consecutive round of corporeality, a phaser sheen must either become incorporeal or spend one charge per round.
