Is it possible for it to be based on an item's qlvl? so say a unique with a qlvl in the range of 91-99 have x% chance for Lo? The reason I say a range is cause I don't think you would want to add 100 recipes for all the Qlvls.

Being said, I'm against this idea... Imagine farming lich king.. 2~ min per run with a guaranteed qlvl of 99 each time. The value of HRs would absolutely plummet
