Steampunker

The  is a hardmode NPC added in the 1.2 update. She will only appear once the player has killed any mechanical bosses (Killing Plantera or the Golem will not trigger her spawn; it must be the Twins, Skeletron Prime, or The Destroyer) and there is a suitable House for her. Once the conditions have been fulfilled, she will move in and begin selling Items.
