Well I guess it's a good thing that the DRK weapon and I wager Tank weapons can't stack Piety after all. I learned something today. With Food I reached a Piety cap. It stops increasing at 415. I'm kinda sad. With Spiced Cider HQ I could have breached 440 but no they had to be lame.

Oh well at least I had gone out of my way to acquire this information.
