A hardcore death this weekend really hurt. It was my Skyfire Grenado build. An Elementalist with heavy investment all around in Lightning damage. From the Lightning pole for the Shaman to the fast Primal Strike, to Grenado from the Demolitionist with the Lightning modifier.
I was doing great in multiplayer, but because our characters were in different parts of the campaign, I had ended up skipping a part of the campaign after the Broken Hills. So after my multiplayer session with my friend was over on Friday, on Saturday I went to single player to finish that section because I hate having outstanding quests on my quest log. And when I entered the Steps of Torment (not the Skeleton key area, just the regular dungeon), I fought something that killed me really fast in one of those big bone graveyard areas. I’m still not sure what exactly killed me. My resists were fairly decent, and nothing was next to me that I saw, so it probably wasn’t melee damage.
In Hardcore I wish there was like a post-mortem screen of some kind, which at least showed you what killed you.
