Congratulations, inmate; you're almost there! With one more block to reap, your freedom seems closer than ever...just make sure to not get stuck! Elite Block has a ton of new features in comparison to A Block. Let's get started, shall we?
Ah, the Snow Mine. This is probably your best bet on making money quickly during your time in Elite - it has many more iron and diamond ore than you've seen thus far. An advisable strategy would be to smelt the iron you get and sell it to the shop, and make diamond shovels and pickaxes out of the diamonds you get. You can then proceed to sell these diamonds for good prices at the Player Market by finding a shop buying diamonds for a better price than the Admin Shop in Elite.
