I dismissed them at first, seemed like a bit like a fetch questy kinda boring thing I didn't care about. Then I checked one right outside the ring and noticed... its "ingredient" cap was much higher... making the items much stronger. You can even make a 9km range lightning turret. Its super inaccurate so it isn't super viable, but still a good example of what you can do if you just max everything out. The railguns also look quite worth while
