I have a question about Divine word. Seeing as it deafens those that fails the save against it, does that mean that a creature can't be affected by it more tthan once? Seeing as it relies on them hearing it? Am I understanding this right or is there something more to the deafend condition? 

Yes, the description says: "Each creature that can hear you...". So if a creature is defeaned, the spell has no effect at all.

That was what I thought, just wonderd if there was some sort of exception of some kind I wasen't aware of. Thanks
