Back in June 2018, Bethesda promised that only cosmetic items would be sold in Fallout 76 for premium currency.
What is known
Bethesda plans to add "Repair Tools" to the store.kits”, which are useful for repairing things from your inventory or camp. They will help players avoid wasting resources and repairing items regardless of time or place. There will be two sets, but players will only be able to purchase one with premium currency. Basic Repair Kits are obtained through gameplay or for “Atoms”, but Improved Repair Kits are earned only through completing activities and so on.
However, this does not change the fact that Bethesdabegins to introduce “game donation”. In addition, in December 2018, rumors appeared about the addition of “Lunchboxes” to Fallout 76. In Fallout Shelters, they give gamers cards with characters, upgrades, and bonuses, and the leak specifically talked about bonuses to damage and experience gained.
