As far as we can tell, this only happens while in the Sands (undead area ). I'm a Radiant Servant with 10 uses/rest, and all of a sudden, ALL attempts will be gone...dropping all the way down to zero. My girlfriend has similar problems in the sands with clickies being mysteriously depleted, her manyshot on timer even though she hasn't used it, and so on. No idea why this happens...nothing unusual in combat log, and my CHA isn't dropped either ( i.e. no mummy rot ). I find it hard to believe something would drop my CHA that much at once, and immediately revert to normal. Is this a glitch or some sort of de-buff being used by the baddies ? Quite the annoyance to have no bursts or divine might at random.
