For me, it was Grim Dawn's final boss during Early Access before he was nerfed. At no point in the game did I have any major trouble with anything, but apparently I would have needed more rarer resistances for him. He kept summoning more and more minions faster than I could kill them, and the minions were very strong. And he also kept spamming some magical lightning strike that could hit me anywhere. The battle site was actually quite big, but with all the minions, I had almost no room to maneuver. No matter where I went, there was an enemy upon me. I think I died like 20 times before I managed to kill him. It wasn't difficult in a fair way, it was completely unfair. So frustrating!
