Recipe

how to obtain
in order to obtain recipes (without trading) you need to find recipe dungeons. the are found slightly rare in your uber trove worlds and can be immediately noticed with a recipe paper on it. After you defeat the boss you get a new recipe in you inventory. Press the left, or right key to get the recipe, or when the recipe is in your inventory press a the get it. To trade recipes go to market place and press a, instead of learning the recipe you put it in your market place item slot And it is ready for trading.

recipes vary. The sheet you get and the recipe you earn depends on where you are. (Example: neon biome neon recipe, and desert biome desert recipe.)

you also get them from mining, a rare ore might appear and when you see it probably break it to see what it has, that is a recipe ore

miners trove
miners troves gives you exact recipes for building yet still can be sold for the same. To get a miners trove simple mine ores and blow things up.

trading
the trading might vary so I will say average about 250 flux, 300 glim, and no eyes. This is completely use less but when you keep selling you might get somewhere with it. Now the megalithic update hit, so now biomes are separated. This means you can sell some items and recipes for more or less.
