Well, my friends, I have killed a PC in my campaign. It was a sad death of a faen akashic (Monte Cook's Arcana Evolved) that involved an animated Vanity. The dashing young faen and his partner was to save a sleeping damsel in distress with the other members of the party distracting the inhabitant of the home. Well, when they entered the bedroom where their quarry laid the vanity dresser attacked and scored a critical hit on the poor faen, doing massive damage and with a failed save...
Death by vanity. A sad way to go.
