Mechanic

The Mechanic is an NPC who must be saved from the Dungeon. She will randomly spawn near you while you are exploring the Dungeon. Talking to her in this state will free her, and she will wander the area until she gets killed by any nearby enemy or hazard, or until you move far enough from her. After that, she will move into an available house like any normal NPC. Note that if she gets killed, you WON'T have to unbind another one (the same with the Goblin Tinkerer and Wizard.)

Once the Mechanic has moved into a house, she will sell the following:
