Good, but a few suggestions

Whenever I sell items to the blacksmith it gives me one gem every time. I think items that are higher in rarity should be sold for more gems instead of just one gem. Another idea I had would be adding different environments to the arena just to make it look better and not as dull. Other than that this is a very good game.
