So maybe I wound up here earlier than I should have, but I managed to get to the point where my entire party was dead except for my main character, a paladin. It was just him, Nemnok, and Kaali who I was desperately trying to keep alive. As I'm writing this, Nemnok is at 50% health and my paladin is at full HP thanks to Exalted Endurance. Nemnok can't kill me, so I'm just sitting here waiting to whittle him down. I'll be back in an hour or two when this fight finishes up.
I'm like some sort of holy warrior who traveled to Hell and is now locked in eternal combat with his enemy.
