I've got a question about how this wondrous item works.
Dead Man's Shroud:
This dirt-stained cloak was woven in shadow from the burial shroud of a condemned murderer. It prevents nonintelligent undead from detecting you, as per the hide from undead spell. Intelligent undead can perceive you if they succeed at a DC 11 Will save. The warding is ended if you touch an undead creature, channel energy against undead, or attack any creature. Once per day as a standard action you can silently call forth the shadows bound into the shroud, rendering you invisible for 5 minutes.
What does this mean in a combat situation, does attacking a creature break the hide from undead effects of the item forever?
I would say that the warding is ended for any creatures near you, or in combat with you. I know it doesn't say that, but it seems crazy that you would lose most of the usefulness of a 6k item for one attack.
It should simply require a standard action to reboot it if you break the effect.
