Or near your house, the Destroyer can MURDER your NPCs. That's why I use a Hellstone Brick Skybridge to prevent most attacks from doing damage and Crystal Storm to fend him off. So anyways, you need to forge the Mechanical Worm to summon him. But ONLY do it at night (or dusk (7:30 PM in-game time) to have enough kill time.) or else you might take thousands of damage, instantly killing you. Like all bosses, if the battle lasts until dawn (4:30 in-game time), The Destroyer will move very quick and flee, leaving you with no reward whatsoever until you defeat him.
