Greatest campaign derailments

[JoshuaZ]

Because in a game where the most developed mechanic is the combat system, the best response to someone using violence in self-defense is to prevent all combat from happening?

It is more doable if one is a moderate pacifist (e.g. try to end encounters without fatalities if one can). Or at least I hope so. I'm going to be playing in a PF/3.5 campaign set in Eberron soon a pacifist necromancer. She's a happy-go-lucky dread necromancer/bard. Fear effects are fun. I'm really looking forward to the first time she runs up to enemies in game and shouts "BOO!"
