Dust battlestaff's drop rate is 1/4000 from dust devils, and I just so happened to get one during a task which made me hit 4k dust devil kc... hmm...
Those brimstone keys could've potentially pushed for over 1m and thus high value, too.

Wow... that was just terrible. Managed to get several times some junk drops that were of the same rarity or rarer as the main unique drops, but that was that.
