Just plop it down and feed it mushrooms and metal. It's like a weird pet that gives you armor instead of affection.

Using the Auto Hammer in Terraria is super simple but super important for getting that sweet Shroomite gear! Just place the Auto Hammer in your crafting area like any other crafting station. Then, with Glowing Mushrooms and Chlorophyte Bars in your inventory, you can craft Shroomite Bars. Make sure you've got plenty of both because that Shroomite armor isn't gonna craft itself!

Tbh, I never found the Auto Hammer that useful. Just stick to the basics and you're golden.
