Was fighting a mind flayer in Missing? Idk, cant' remember.
Favored soul, or maybe a cleric, idk. Details escape me. He casts sunburst I think. Its the one that makes the big globe thing, like celestia does sometimes. While im fighting the flayer. Or did the flayer cast it? IDK. Boom over 300 hp gone. I lived.
But hardcore being hardcore, you tend to run in the same group of people. As I leveled, this player was in my group several more times. And I could've swore that darn sunburts kept going off directly on top of me over and over and over... quest after quest after quest...
Never took damage after that one time though.
