Just killed nightmare duriel for the first time on my summoner necro and nothing dropped but like 6 town portal scrolls. Pretty sure that isnt intended.
Not a bug.
It has always been this way. Sometimes he drops items. Sometimes he only drops Town Portal Scrolls — Anywhere from 1 to 6. I’ve never seen more than 6 though.
I don’t recall the difficulty or whether it was the first kill or not, but Dury seems to have a knack for lowsy drops. I do recall a time when 4 tps or so were the loot.
Tbh that sounds very much like Blizzard screwed up as usual, and as usual was too stupid to fix it so they left it in as a “feature”.
