Yesterday I spent hours looting with Nayana and Des/Pirate/Grendel. I got a couple of levels (notoriety 42 and dagger 23), but as it got later and later I was certain I wasn't going to get anything good, with my luck.
But then, POW
MASTERWORK BROADSWORD! It's the best sword I've ever wielded. Thank you, mines!
(there was something else in that skull chest, but I took it before I noticed the blue letters)
