I did another run through Kara yesterday, though we still have to finish up the last few bosses (Illhoof, Chess, Netherspite, Prince). After downing Nightbane I was hoping to see that Nightstaff of the Everliving had dropped. Unfortunately it didn't, which is beyond me because from my sources it has the highest drop rate of all Nightbane's loot. But! I did get Stonebough Jerkin from him and also Ribbon of Sacrifice from the Big Bad Wolf! Now I just hope that Light's Justice drops from Prince when we go back to finish it.
I would be one happy tree to see that finally drop!
