Questing my then-Zealer-now-Uber-Smiter, late the other night, had to blink a few dozen times to register what was lying there. This beats the Death's Web I found years back off Baal as the rarest item that has dropped for me. Sadly I've found a total of 1 white/Eth Berserker Axe in my time playing since restart.
Have had good luck with skillers over the last ~month, this may be the best though.
Recent LK running spree to get Infinity finished up - was looking for Sur and found a Ber off a poppable (this makes my third corpse Ber from LK, Lo being the highest I've found in a actual superchest in ~2kish runs). TP Books roughly corresponding to when runes were found.
Some Pits between Key runs on my trapper
Still waiting for the Night Wings.
Despite my somewhat crazy rune luck over the last few months (Started with a Jah in July from Mephisto, and within two months or so I've made Enigma-Hoto-Fortitude--+6 CTA - Infinity - Exile - Grief, I have still to find: War Trav's, Mara's, SOJ, BK, and Tal's Armor and Amulet and even a Dual leech ring. The HR drops seem inevitable at this point, but my otherwise pumped toons are running around with bargain bin jewelry and shoes
