So let me preface that I am playing the (or close to the) latest version of DF under the stricture that my dwarves are pacifists. No killing, no violence except personal self defense. No militia. Cage traps are the only traps allowed.
A minotaur has shown up, killed a Yak and Bunny and knocked one of my dwarves unconscious. Now it's beating him in the head with a cave spider silk sock, which isn't doing much. My dwarves keep running up to feed or recover the wounded dwarf. This is putting a severe hindrance on productivity in the fortress.
What can I do? The only I have is to build a wall around the area. Is there a way I can make the minotaur my friend? Something else I can do without actually killing it?
