Arena is pretty good, you get 2 stars and keys as you increase your win streak. The epic boss gives a good amount of armors from higher level rewards; at level 21 you get 15, 1 stars.

Otherwise you'll be stuck gathering materials from bosses and enemies. If you can, farming the wind level mini bosses on epic for the 5 pieces of crafting material a piece.This method is very good for getting 2 star armors.
