I had thought about doing such a [pacifist] character off and on for a while... Both my priest and my rogue try not to hit anything, although there's always a chance of a misclick when trying to open a quest item with mobs fighting near it. Both of them always wield a fishing rod, so any accidental hits won't increase their weapon skills. Neither of them will do quests where they have to kill things.

I started [my undead priest] from a roleplaying point of view, based very loosely on a real German priest, Franz Reinisch, who refused to serve in Hitler's army and was executed... As a rogue is a sort of "spy" class, I Googled for a pacifist spy and found Noor Inayat Khan, a woman who was also executed by the Nazis for aiding the French resistance, so I named my rogue after her. She was the daughter of a well-known pacifist in India.
