Testimonials seem to be all over the place, so I logged everything when I started farming Lilith. I went blu/drk for tp suppression, and brought a thf mule for th8. Every fight was done on E.
I understand random is random, and anecdotal evidence is anecdotal, but for anyone interested, here are my results:
Fight 19: Head #1
Fight 33: Boots #1
Fight 52: Head #2
Fight 54: Body #1
Fight 56: Earring #1 (that was a nice string of drops over 5 fights, random is random)
Fight 63: Boots #2
Fight 64: Earring #2
(things slow down now that I've got a few of the drops)
Fight 99: Legs #1
Fight 118: Legs #2
(things really slow down now, main 4/5 and mule 3/5)
Fight 152: Boots #3 (brought a friend along for a few runs)
Fight 154: Body #2
Fight 161: Gloves #1
Took me a total of 161 runs to go 5/5 on my main, and 4/5 on surplus drops for my mule.
