As you should know, weapons and gear is randomized with some being really great and rare with mixed stats. This can be good and bad at times especially when the ghostly merchant comes by on C-level. I found an armor plate of SuperKill's set like Notors or Kintos.
One I found:
SuperKill's Plate of Evil Worship Lvl. 5
+22 Critical Chance
+12 Death Strike
Where to findEdit
Again, like any game with implicit design, you have to be persistant to accomplish what the designer has you do. I was fortunate to find this armor plate because it included a +12 DeathStrike bonus!!!
