How much have you grinded for one pice of glamor?

I've just completed my 20th run on Ktisis Hyperboreia trying to get the reaper chest piece.
I've seen every piece of gear multiple times now but never the chest piece. I'm starting to believe there actually isn't one in this dungeon.

What's the longest you have run a dungeon for grinding out one piece?

There are still dungeon drops I've never been able to get. The current loot system was not put in place until ShB, so in dungeons prior to then it is total RNG.

Oddly enough though, I was just running Vanaspati several times on my MNK trying to get the chest piece. I think I ran it four times because I didn't want to out level the MSQ too much trying to get it. I got nothing but accessories during those runs. Then I run it one time on my SCH, and I score the chest piece for my MNK.
