Anyone know the proc rate for the "Occasionally negates MP cost" effect?

Not enough for it to be worth a couple million cruor--being serious; if you are dying enough to need AoE Reraise aura, or are having MP issues, the fight is already lost.

I would mainly use it for pugs. Don't know how many times people fail to proc and consumables are down for lengthy periods (why is it almost always darkness that never gets hit?). Plus these days curor does not translate to gil so well.

While the 10% dmg reduction and re-raise sphere won't win you any epeen contests on the parses, I believe the utility serves you better in a pug situation. Of course if you're in a LS group you really shouldn't be having issues and probably won't need to use it.
