Well, this is my first Hardcore death of this Ladder season and it is one that leaves me scratching my head as to what exactly happened :
My Level 81 Smite / Zealot Paladin, "Phil_TheLilBoy", was doing one of his endless MF'ing / leveling runs in Lower Kurast, just like he (and my other Hell characters) have done many, many times in the past. Nothing out of the ordinary happens (OK, he did get rather hard hit by a bunch of Doom Apes but nothing that shouldn't have been easily handled.)
Then he runs up against the mob that you see in the screen shot.
What is very frustrating about this is, although the boss has Conviction, my Paladin was not engaged in combat with him, when he got one-hit-killed - he was running away from one of the other members of the boss pack.
Resists were 75 / 75 / 60 / 50, the Paladin had 1200 hit points and max block and although the boss monster was Lightening Enchanted, I don't know how one or two subordinate pack monsters could possibly have done enough damage to kill poor Phil in one hit. (Keep in mind, this is a character that, with lots of rejuves, killed Uber Diablo. And he gets one-hitted by some damn boss Zakarumite in Act III.)
(N.B. -- The Amp that you see in the picture was from my late Merc's Witchy bow, now sadly lost along with everything else because not only was I not lootable, but the game disappeared right after I was killed... I couldn't even join with my Druid to get some revenge.)
What is worse is that almost all my good melee weapons, everything from a Butcher's Pupil to various good rares, were in his stash.
This game is ridiculous... no matter how well you play, sooner or later some monster with bugged damage is going to get you.
