The Mechanic is an NPC who sells various mechanisms, as well as Wire Cutters and Wrenches, allowing the player to construct and activate wired devices like traps and critter engines. She can be found in the Dungeon in the Cavern layer or below after killing Skeletron, where she spawns randomly as the stationary Bound Mechanic. Talking to her in this state will free her, after which she will respawn as long as a vacant house is available, even if killed.

On the  PC,  Console,  Mobile,  Old Chinese,  tModLoader, and  tModLoader Legacy versions, the Mechanic will attack nearby enemies. She will throw her Combat Wrench / Wrench like a boomerang to defend herself, dealing 11 / 16 / 19 damage at the start of the game; on the  PC,  Console,  Mobile, and  tModLoader, as players progress she will gain various stat increases. She can drop her weapon upon death.

The Bound Mechanic is one of the few entities that can be detected by the Lifeform Analyzer or its upgrades.

When submerged in Shimmer, the Mechanic will transform into her Shimmered form. This has no impact on gameplay or dialogue and is only a visual change. She can be returned to her classic look by submerging her in Shimmer again.

Quotes

Interaction quotes

"Always buy more wire than you need!" "Did you make sure your device was plugged in?" (Possibly a reference to "The IT Crowd", or a general statement made by many people in IT about "malfunctioning" devices.) "Oh, you know what this house needs? More blinking lights." When Goblin Tinkerer is present: "Hey, <Name of Player>, did you just come from <Name of Goblin Tinkerer>'s? Did he say anything about me by chance? When Arms Dealer is present: "<Name of Arms Dealer> keeps talking about pressing my pressure plate. I told him it was for stepping on." When Tavernkeep is present: "<Name of Tavernkeep> offered me a Root Beer, I told him to give it to me in a square cup." (Reference to a math joke; mathematical squares and square roots cancel each other out, therefore the result is simply beer.) When found in Dungeon: "Thanks! It was just a matter of time before I ended up like the rest of the skeletons down here." When homeless: "Hey, watch where you're going! I was over there a little while ago!" "Hold on, I've almost got wifi going down here." "But I was almost done putting blinking lights up here!" "DON'T MOVE. I DROPPED MY CONTACT." (A pun on "contact", a device that an electrical current passes through, and "contact lens") During Blood Moon: "All I want is for the switch to make the... What?!" "Oh, let me guess. Didn't buy enough wire. Idiot." "Just-could you just... Please? Ok? Ok. Ugh." (Possibly a reference to "How I Met Your Mother") "I don't appreciate the way you're looking at me. I am WORKING right now." During a Party: "Do you think anyone would mind if I wired a cake with bulbs instead of candles?" During a Windy Day: "My wires are getting tangled in this cyclone. Watch where you step!" "Oh no! There are pockets of low pressure rolling in, I must secure the power grid." During Rain: "Oh Fudge! Shorted out another outlet! I hate this weather." "If it doesn't stop raining, my wrench is going to get all rusty!" During a Thunderstorm: "Don't go outside right now while holding any of my products, you'll attract an unwanted dose of electrical power!" "Great! There goes another pump. When will the lightning stop frying my equipment?!" When in a Graveyard: "I should light up this dark and scary place to keep the monsters away." "I'd run some wire here, but the spooky dead things are in the way!"

Happiness quotes

When homeless: "I need some sort of structure to run these wires through." When far from home: "Oh, it seems I'm out of signal range! Hmm." When in a sparse area: "Perfect, no one is in the way for building infrastructure." When overcrowded: "The flickering lights are bothering me. Is there a load on the grid?" "I'm going to need a way bigger power source for THIS MANY people, I hate it!" When in the Snow biome: "I like the Snow, machines don't overheat here, and the energy flow is efficient." When in the Caverns: "I don't like the Underground, it reminds me of a traumatic experience!" When in an Evil Biome or the Dungeon: "I feel extremely uncomfortable in the Corruption/Crimson/Dungeon, as if creeping eyes are always watching me." When near the Goblin Tinkerer: "Umm... <Name of Goblin Tinkerer> makes my heart flutter, I need to get that checked!" When near the Princess: "<Name of Princess> hotwired one of my pumps, I'm super impressed!" When near the Cyborg: "I feel like I understand <Name of Cyborg> better than anyone else." When near the Arms Dealer: "I don't really like that <Name of Arms Dealer> won't leave me alone!" When near the Clothier: "I hate how <Name of Clothier> doesn't know how to treat a woman!" (Reference to the Clothier leaving her in the Dungeon) When neutral: "Everything's working correctly - oh, me? Yeah I'm fine!"

Notes

• Although the topmost corridors of the Dungeon may be accessible prior to defeating Skeletron, the Mechanic will only be found at Cavern height. Therefore, encountering her always requires defeating Skeletron, because the Dungeon Guardians spawning below zero depth will override all Dungeon spawns.
  • In a drunk world, the level at which Dungeon Guardians spawn is lower, therefore it's possible for the Bound Mechanic to be encountered before defeating Skeletron.
• The Mechanic can be housed in the underground Snow biome with the Tinkerer, without the penalty, for maximum NPC happiness. Since the Snow biome extends through the underground until it reaches the cavern layer, her preference for the Snow biome will override her dislike of the Underground.

Trivia

The Mechanic during a Party

• There appears to be conflict between the Mechanic and Nurse during a Blood Moon. 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 judging by some of the Goblin Tinkerer's quotes, he has a crush right back.
  • This is also proven by her happiness quote, "Umm... <Name of Goblin Tinkerer> makes my heart flutter, I need to get that checked!"
  • When submerged in Shimmer, both the Mechanic and the Goblin Tinkerer become green goblins.
• Rarely, the Nurse and Mechanic can both have the same name, either Kayla or Amy. This can cause the Merchant to say on a Blood Moon, "Oh, great. I can hear Kayla/Amy and Kayla/Amy arguing from here."
• The line, "<name of Arms Dealer> keeps talking about pressing my pressure plate. I told him it was for stepping on." is a vague sexual reference. The Arms Dealer is apparently hitting on the Mechanic, using innuendo, but she doesn't get the euphemism and takes his comment literally.
  • This might be the reason of the conflict between the Nurse and the Mechanic, since the Nurse has a crush on the Arms Dealer.
• During a party, when the Mechanic dons a party hat, her hairstyle is different: she wears it down instead of up in a bun. This makes sense as wearing a party hat while having hair in a bun would be cumbersome.
• Her ability to throw her wrench like a boomerang to defend herself may be a reference to Ratchet from the Ratchet & Clank games, who can do the same move.
• Some of her names, "Autumn", "Dawn", and "Ginger", are references to the color orange and thus to her red hair.
•  – According to the official game lore, the Mechanic was being forced to rebuild Cthulhu piece by piece by the Cultists, which explains the presence of all mechanical bosses. Additionally, she never finished Cthulhu's mechanical brain, which would account for BoC's lack of a mechanized counterpart.
• The Mechanic hates the Clothier, most likely because he was the one who tied her up and left her in the Dungeon, as referenced by one of his quotes.
  • Although she and the Clothier have a mutual hatred for each other, they do not appear to know why, as she only vaguely mentions that he "doesn't know how to treat a woman", while the Clothier only has vague recollections of throwing her in the Dungeon while possessed by Skeletron.
  • Her dislike of the Caverns due to "a traumatic experience" likely refers to this incident as well.

The Bestiary entry for the Mechanic: "The Mechanic was imprisoned for her aptitude in engineering. She sells wiring and tools for putting together anything imaginable."
