What if we had the ability to craft rare accessories from rare ingredients? For example: the zee core, dropped by Slooms, is incredibly rare and isn't used in any recipes. How about you toss in some blue shards, a few scrap metals, a zee core, and a volcanic iron, and ta-dah! You have a Zee Crest. Or perhaps some Gremlonium and other gremlin related materials combine to form a pair of Gremlin Goggles. It's a three way victory. Generally unused ingredients are used, we can actually craft accessories, and more accessories are added.
