|The Shifty Mongoose|
My first and only PC death was in Round One of a boss fight, where my unhinged aberrant halfling sorcerer said exactly the wrong thing to a spiteful large-sized villain with a X4 crit weapon. One confirmed crit later, and he was dad from full HP with no hope of Life getting Breathed back into him.
We chose not to raise him, because I found it the most appropriate time & place for him to die, I was afraid of that character getting into the endgame, and the group wasn't cohesive at all. Two other people died in that AP (Jade Regent), and the new characters got along well.
In Kingmaker, we just got through Book One, and have had four deaths, three of which were from the same player who got bored with his character ideas (except for the first one, who left when nobody could stand him). Other players left, but their characters didn't die.
