These achievements require that you complete one and then three different collections in the game. Each of the ten locations have a collection of ten items that you can complete. These items are only obtained randomly in luggage that you open and appear at a very infrequent rate. To complete a collection, you need to play on that specific location and open as many luggage as possible until you get all ten items. After reaching Level 46, you should then return to the locations where you already have the most complete collections. Continue grinding the game until you complete the collection and then move on to another location.
