what it unlocks
This is the gate on the entire steampunk furniture line, and that line is unusual because you never have to go find the material. The Steampunker sells cogs outright, so once the boiler is down the only limit on how much brass and rivet you can build is how much money you feel like spending. Compared to farming a biome for a themed wood, that is a very easy supply.
when it is available
She does not move in until Hardmode is properly underway, so this is a decorating project for a world with some history behind it. Set the boiler up somewhere permanent and central rather than in the room you happen to be working on, because you will be walking back to it constantly.
