Mechanic

The Mechanic is an NPC who must be saved from the Dungeon after killing Skeletron. 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.)

Items sold
Once the Mechanic is freed, she will sell the following:

Names
The mechanic may have any of the following names:

Note
There is NO possibility that the Mechanic is found in a world where the Skeletron is not killed. This is due to the fact that the Mechanic only spawns where normal Dungeon monsters spawn (below 0 depth) and her spawning is inside the normal spawning loop like monsters and critters, and when the Skeletron is not killed, the Dungeon Guardian will always override the spawning result.

Trivia

 * There appears to be conflict between the Mechanic and Nurse during a Blood Moon. When both are present, they have various hostile sayings that replace their standard quotes (see Quotes). During this time, the Merchant has a chance of saying, "Oh, great. I can hear (Name of Mechanic) and (Name of Nurse) arguing from here."
 * The Mechanic has a crush on the Goblin Tinkerer, as referenced by her quotes, and, also referenced by some of his quotes, he has a crush right back.
 * Apparently, the Clothier was the one who tied up and left the Mechanic in the dungeon, but he doesn't remember. Well, sort of.
