Re: Ethereal Volley
I'm confused as to your reference to a feat and melee weapons. Projectiles are the only valid targets, and it makes the projectiles ghost touch. There is a psionic feat which improves your odds on hitting incorporeal targets, are you comparing to that? It seems to be a more easilly comparible to the weapon ability, or to the keen edge spell. It's a level lower than keen edge, but it's less generally usefull, and uses up a precious power known slot even on days where you don't encounter any incorporeal foes.
