The Last Kids on Earth and the Staff of Doom

There are a total of 14 armors and the improvement ranges from 200 to 700 money, which in total would be 2700 per armor and 37,800 for all the armors.

It is very sure that you will have plenty of money when you finish the game and improve all the weapons.

Don't be afraid to spend money, you will get enough to buy and upgrade everything by completing all main and side quests as well as challenges and opening chests on the map.

If you think that the money is not going to reach you, you can use the trick of the saved game in the cloud.

Sorry if my English is somewhat wrong.
